Basic Features
Safety and Reliability
Ultra Short Body
Isolated Power Supply and Input Circuits
The body depth has been greatly reduced. Helps in making thinner control panels.
Power supply circuit and input circuits are isolated inside the Counter/
Tachometer. Previous non-isolated counters had wiring restrictions
and could be damaged if wired incorrectly. The H7CX removes these
worries.
Note: Except 12 to 24-VDC models.
12 to 24-VDC Models with Screw Terminals: 59 mm
100 to 240-VAC Models with Screw Terminals: 78 mm*
Models with Sockets: 63.7 mm (case dimension)
* Power supply circuit and input circuits are isolated for safety and reliability.
Set Value Limit
You can set an upper limit for the set value to prevent unexpected
operation of output devices caused by setting mistakes.

Easier to Read
For better readability, the character height for the present value
display is 12 mm on models with 4 digits, the largest class in the
industry. The wide viewing angle and brightness provide excellent
visibility. The number of display segments has also been increased to
make settings easier to understand, and the present value display
can be switched between red, green, and orange so that output status
can be seen from a distance.

Output Counter
(Display example)
Note: The display color can be switched on all models except for the
H7CX-A11 and H7CX-R11.
The output counter counts the number of times the output turns ON
(alarms can be displayed and the count can be monitored in
increments of 1,000 operations). This counter is useful in managing
the service life of the Counter/Tachometer or the load.
The Easiest Operation
Operation is simplified by the
Up/Down Key for each digit
on 4-digit models and Up
Key for each digit on 6-digit
models.

The H7CX's panel surface is water-resistive (conforming to IP@6,
UL Type 4X) and so even if drops of water penetrate the gaps
between the keys, there will be no adverse effect on internal circuits.
If, however, there is a possibility of oil being present on the
operator's hands, use the Soft Cover. The Soft Cover ensures
protection equivalent to IP54F against oil. Do not, however, use the
H7CX in locations where it would come in direct contact with oil.

Protecting the Counter/Tachometer in Environments
Subject to Oil
The Front Panel is attached to the
Counter/Tachometer with tabs in
four locations. To remove the
Front Panel, open the tabs and
pull the Front Panel forward. To
attach the Front Panel, press it
onto the Counter/Tachometer so
that all four tabs lodge into the
grooves on the body of the
Counter/Tachometer.
Note: The
Waterproof
Packing is
included with
models with
screw
terminals.
Order the Waterproof Packing
separately if it is lost or damaged. The
Waterproof Packing can be used to
achieve IP66 protection.
The Waterproof Packing will deteriorate, harden, and shrink
depending on the application environment. To ensure maintaining the
IP@6, UL Type 4X waterproof level, periodically replace the
Waterproof Packing. The periodic replacement period will depend on
the application environment. You must confirm the proper
replacement period. Use 1 year or less as a guideline. If the
Waterproof Packing is not replaced periodically, the waterproof level
will not be maintained. It is not necessary to mount the Waterproof
Packing if waterproof construction is not required.

Explanation of Functions
Items marked with stars ★ can be set using the DIP switch.
Input Mode (cntm)★
Prescale Value (pscl)
Set increment mode (UP), decrement mode (DOWN), or one of the
increment/decrement modes (UP/DOWN A, UP/DOWN B, or UP/
DOWN C) as the input mode.
Input modes other than UP or DOWN modes cannot be set using the
DIP switch and so use the operation keys if other modes are required.
(For details on the operation of the input modes, refer to Input Modes
and Present Value on page page 21.)
Pulses input to the counter are converted according to the specified
prescale value.
(Setting range: 0.001 to 99.999 for 6-digit models and 0.001 to 9.999
for 4-digit models.)
Example: To display the feed distance for systems that output 25
pulses for a feed length of 0.5 m in the form @@.@@ m:
1. Set the decimal point position to 2 decimal places.
2. Set the prescale value to 0.02 (0.5 ÷ 25).
Dual Count Calculating Mode ( calm)
When using as a dual counter, select either ADD (addition) or SUB
(subtraction) as the calculation method for the dual count value.
ADD: Dual count value = CP1 PV + CP2 PV
SUB: Dual count value = CP1 PV − CP2 PV
0.5 m
Output Mode (outm)★
Set the way that control output for the present value is output. The
possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H.
Output modes other than N, F, C, or K-1 cannot be set using the DIP
switch and so use the operation keys if other modes are required. The
output modes that can be set vary with the model.
(For details on the operation of the output modes, refer to Input/
Output Mode Settings on page page 22.)
One-shot Output Time (otim)★
Set the one-shot output time (0.01 to 99.99 s) for control output.
One-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is
selected as the output mode. Output times other than 0.5 s or 0.05 s
cannot be set with the DIP switch and so use the operation keys if
other settings are required.
One-shot Output 2 Time (otm2)★
Set the one-shot output time (0.01 to 99.99 s) for control output
(OUT2).
One-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is
selected as the output mode. Output times other than 0.5 s or 0.05 s
cannot be set with the DIP switch and so use the operation keys if
other settings are required.
One-shot Output 1 Time (otm1)
Set the one-shot output time (0.01 to 99.99 s) for control output
(OUT1).
One-shot output can be used only when D, L, or H is selected as the
output mode.
If the output time is set to 0.00, hold is displayed, and outputs are
held.
Counting Speed (cnts)★
25 pulses
Encoder
• Observe the following points when setting a prescale value.
Set the set value to a value less than {Maximum countable value
− Prescale value}.
Example: If the prescale value is 1.25 and the counting range is
0.000 to 999.999, set the set value to a value less than 998.749
(= 999.999 − 1.25).
If the set value is set to a value greater than this, output will not turn
ON.
• Output will turn ON, however, if a present value overflow occurs
(FFFFFF or FFFF).
Note: If the prescale value setting is incorrect, a counting error will
occur. Check that the settings are correct before using this
function.
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. When using a two-wire sensor, select NPN
input.
The same setting is used for all external inputs.
For details on input connections, refer to Input Connections on page
page 9.
Display Color (colr) (Displayed for terminal block models
(except H7CX-A11@) only.)
Set the color used for the present value.
Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2

Absolute Value Setting/Forecast Value Setting (setm)
Output ON Count Alarm Set Value (on-a)
For the 2 count output mode, an absolute value setting (abs) or
forecast value setting (ofst) can be set for set value 1.
When a forecast value is set, specify the forecast value set value (i.e.,
the deviation for the set value).
The forecast output (output 1) turns ON when the present value
reaches the forecast value.
If the forecast set value is greater than or equal to the set value, the
forecast output (output 1) will turn ON as soon as counting starts.
Set the alarm value for the output ON count.
The limit can be set to between 0 × 1000 (0 times) and 9999 × 1000
(9,999,000 times). Only the underlined values are set. The alarm will
be disabled if 0 is set.
If the total ON count of the output exceeds the alarm set value, e3
will be displayed on the Timer to indicate that the output ON count

Counter
Total and Preset Counter Operation
The H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value.
• The total counter continues to count the total
accumulated value when the present value is
reset using reset/reset 1 input (Reset Key).
• The total count value is reset when the total
reset/reset 2 input is turned ON.
If the Reset Key is pressed while the total count
value is displayed, the total count value is reset.
The present value is also reset at this time.
• The counting range of the total counter is
−99,999 to 999,999 (−999 to 9,999). The total
count value returns to 0 when it reaches the full
scale limit.

• The batch counter continues after count
completion.
• Batch output is held until batch counter reset is

• When the batch counter reset input is turned
ON, the batch count value is reset, and batch
output turns OFF.
• If the Reset Key is pressed while the batch
count value is displayed, the batch count value
is reset and batch output turns OFF. The
present value is also reset at this time.
• The count value can be incremented and
decremented.
The batch count is only incremented.
• The maximum counting speed for batch counter
operation is 5 kHz. The batch counter counts
the number of times the count reaches the set
value.
The batch count value is held at 0 during batch counter reset input.
If the batch count set value is 0, batch count will be performed but there will be no batch output.
The batch count value returns to 0 when it reaches 999,999 (9,999 for 4-digit models).
Once batch input has been turned ON, it will return to the ON state after power interruptions.
If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON.
After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch count value.
Dual Counter Operation
Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for
which output turns ON when the set value matches the added or subtracted result.
(1) Dual Count Calculating Mode = ADD
Dual count value = CP1 PV + CP2 PV

The CP2 present value is reset when reset 2
input is turned ON.
• If the Reset Key is pressed while the dual count

is displayed, all of the present values are reset
and outputs turn OFF. At this time, counting is
not possible for CP1 or CP2 inputs.
OUT1, OUT2
Note: The above is for when the output mode is K-2.
SUB mode can be used only when K-2, D, L,
or H is selected as the output mode with
6-digit models.
Note: 1. Counting is not possible for CP1 during reset 1 input. CP2 will not be affected. The dual count value will be calculated based on a CP1 present value of 0.
2. Counting is not possible for CP2 during reset 2 input. CP1 will not be affected. The dual count value will be calculated based on a CP2 present value of 0.
3. The counting range for the dual count value is −99,999 to 999,999 (0 to 9,999 for 4-digit models).
The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999 (0 to 9,999 for 4-digit models).
If a present value exceeds 999,999 (9,999 for 4-digit models), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting
will stop.

Tachometer Output Mode (totm)★
Set the output method for control output based on the comparison
value. Upper and lower limit (HI-LO), area (AREA), upper limit (HI-HI),
and lower limit (LO-LO) can be set.
(For details on the output modes, refer to Output Mode Settings and
Operation on page page 34.)
N: Number of pulses per revolution
d: Diameter of rotating body (m)
πd: Circumference (m)
d: Diameter

• Observe the following points when
setting a prescale value.
Set the set value to a value less than {Maximum countable value −
Prescale value}.
Example: If the prescale value is 1.25 and the counting range is
0.000 to 999.999, set the set value to a value less than 998.749 (=
999.999 − 1.25).
If the set value is set to a value greater than this, output will not turn
ON.
* Output will turn ON, however, if a present value overflow occurs (FFFFFF or FFFF}.
Note: If the prescale value setting is incorrect, a counting error will
occur. Check that the settings are correct before using this
function.
Averaging Method (avgt) (Only for Tachometer Operation)
A simple average or moving average can be selected for the
averaging. With the moving average method, the average of the
measurement values is displayed each sampling cycle, in contrast to
a simple average, with which the the average of the set number of
samples is displayed.
Number of Averaging Times (avgn)★
Decide the decimal point position for the measurement value, OUT1
set value, and OUT2 set value.
Flickering display and output chattering can be prevented using
average processing. Average processing can be set to one of four
levels: no average processing, 2 times (i.e., the average of 2
measurement values), 4 times, 8 times, or 16 times.
The measurement cycle will be equal to the sampling cycle multiplied
by the average processing setting (i.e., the number of times).
Average processing enables stable displays even for fluctuating input
signals. Set the optimum number of times for the application.
Prescale Value (pscl)
Auto-zero Time (auto0)
Counting Speed (cnts)★
Set the maximum counting speed (30 Hz/10 kHz) for CP1 input.
If contacts are used for input signals, set the counting speed to 30 Hz.
Processing to eliminate chattering is performed for this setting.
Decimal Point Position (dp)
It is possible to display the rate of rotation or the speed of a device or
machine to which the H7CX is mounted by converting input pulses to
a desired unit.
If this prescaling function is not used, the input frequency (Hz) will be
displayed.
It is also possible to specify time (seconds) as the display value. Refer
to Display Unit on page page 31 for details.
The relationship between display and input is determined by the
following equation. Set the prescale value according to the unit to be
displayed.
Displayed value = f × α
f: Input pulse frequency (number of pulses in 1 second)
α: Prescale value

The display can be force-set to 0 if there is no pulse for a certain
period of time. This time is called the auto-zero time. Set the auto-zero
time to a time slightly longer than the estimated interval between input
pulses. Accurate measurement is not possible if the auto-zero time is
set to a time shorter than the input pulse cycle. Setting a time that is
too long may also result in problems, such as a time-lag between
rotation stopping and the alarm turning ON. The auto-zero time is not
applied to pulse width measurements.
Startup Time (stmr)
To prevent undesired outputs resulting from unstable inputs
immediately after the power supply is turned ON, it is possible to
prohibit measurement for a set period of time, the startup time.
It can also be used to stop measurements and disable outputs until
the rotating body reaches the normal rate of rotation, after the power
supply to the H7CX and rotating body are turned ON at the same time.

Peak/bottom Hold Enabled (dhld)
This function records the peak and bottom (i.e., minimum) after
counting starts (after turning ON the power supply or changing the
configuration selection mode or function setting). The peak value is
also held when the power supply is interrupted.
OUTY2
Set the hysteresis for when
the output turns OFF.
Output OFF Delay (offd)
This function delays the timing for turning OFF comparative output by
a certain time.
The ON time can be held for the set time if the comparative result
changes in a short time.
Operation will continue and outputs will not change when holding the
value.
Set Value Upper Limit (pl-h)
Set the upper limit for the set value when it is set in run mode. The
limit can be set to between 1 and 999999.
Output Allocation (otst)
When using an H7CX-AU@-N model as 2-stage counter, each output
can be flexibly allocated to either stage 1 or 2.

Pulse Cycle Measurement/Pulse Width Measurement
(calm)
Set the measurement mode to pulse cycle measurement or pulse
width measurement.
With pulse cycle measurement, the number of pulse cycles that occur
in 1 s is measured.
With pulse width measurement, the ON time for one pulse is
measured.
An input OFF period of at least 20 ms is required for pulse width
measurement.
If there is no input pulse during pulse width measurement, the
previously measured value will be held.
Display Unit (unit)
When pulse cycle measurement is used, set the display unit to Hz
(hertz) or s (seconds).
Counting Interval (intv)
If the measurement speed is 10 kHz when pulse cycle measurement
is used, set the measurement interval to 200 ms or Cont (10 ms min.).

The mounting panel thickness should be 1 to 5 mm.
To allow easier operation, it is recommended that
Adapters be mounted so that the gap between
sides with hooks is at least 15 mm (i.e., with the
panel cutouts separated by at least 60 mm).
It is possible to horizontally mount Timers side by
side. Attach the Flush Mounting Adapters so that
the surfaces without hooks are on the sides of the
Timers. If Counters/Tachometers are mounted side
by side, however, water resistance will be lost.

Protecting the Timer in Environments Subject to Oil
The H7CX's panel surface is water-resistive (conforming to IP@6,
UL Type 4X) and so even if drops of water penetrate the gaps
between the keys, there will be no adverse effect on internal circuits.
If, however, there is a possibility of oil being present on the
operator's hands, use the Soft Cover. The Soft Cover ensures
protection equivalent to IP54 against oil. Do not, however, use the
H7CX in locations where it would come in direct contact with oil.
Hard Cover

Connection Sockets
Refer to Connection Sockets on page page 13 for details.
Optional Products for Track Mounting
Refer to Optional Products for Track Mounting on page page 14 for details.
42
Order the Waterproof Packing separately if it is lost or damaged.
The Waterproof Packing can be used to achieve protection equivalent
to IP66.
(The Waterproof Packing will deteriorate, harden, and shrink
depending on the application environment. To ensure maintaining the
NEMA4 waterproof level, periodically replace the Waterproof
Packing. The periodic replacement period will depend on the
application environment. You must confirm the proper replacement
period. Use 1 year or less as a guideline. If the Waterproof Packing is
not replaced periodically, the waterproof level will not be maintained.)
It is not necessary to mount the Waterproof Packing if waterproof
construction is not required.

Explanation of Functions
Basic Functions
Input Mode
The mode can be switched between tachometer mode and AMDcompatible mode.
Tachometer Mode
Use this mode to measure the pulse frequency (Hz).
AMD-compatible Mode
Use this mode to measure the pulse cycle (s).
Cycle (s)
Counting Speed
Set the maximum counting speed (30 Hz/10 kHz) for input. If contacts
are used for input signals, set the counting speed to 30 Hz.
Processing to eliminate chattering is performed for this setting.
Output Mode
Set the output method for control output based on the comparison
value.
Upper and lower limit (HI-LO), area (AREA), upper limit (HI), and
lower limit (LO) can be set. For the H7CX-RW@, the upper limit (HIHI) and lower limit (LO-LO) can be set. (For details on the operation
of the output modes, refer to Output Mode Settings on page page 49.)
Averaging Method (avgt)
Simple averaging (SMP) or a moving average (MV) can be selected
for the averaging method.
With a moving average, the average measurement value is displayed
every sampling cycle or pulse cycle, in contrast to simple averaging,
for which the average value is displayed for the set number of
samples.
Number of Averaging Times
Flickering display and output chattering can be prevented using
average processing. Average processing can be set to one of four
levels: no average processing, 2 times (i.e., the average of 2
measurement values), 4 times, or 8 times.
For a measurement frequency of 5 Hz or higher using a tachometer,
the average will be equal to the sampling cycle (200 ms) multiplied by
the averaging setting (i.e., the number of times).
For less than 5 Hz, the frequency will be measured when the input
pulse comes. Average processing produces a stable display even for
fluctuating input signals. Set the optimum number of times for the
application.
If AMD-compatible mode is used, the measurement cycle will be
measured when the input pulse is received. The output will change,
however, when the comparison value is exceeded even if averaging
is enabled.
NPN/PNP Input Mode
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. When using a two-wire sensor, select NPN
input.
The same setting is used for all external inputs.
For details on input connections, refer to Input Connections on page
page 40.
Advanced Functions
Decimal Point Position (dp)
Decide the decimal point position for the measurement value and
comparison value.
Prescale Value (pscl)
It is possible to display the rate of rotation or the speed of a device or
machine to which the H7CX is mounted by converting input pulses to
a desired unit.
If the default prescaling value (1,000) is used, the input frequency
(Hz) will be displayed.
The relationship between display and input is determined by the
following equation. Set the prescale value according to the unit to be
displayed.
Displayed value = f × α

α: Prescale value

N: Number of pulses per revolution
Example: In order to display the rate of rotation for a machine that
outputs 5 pulses per revolution in the form @@.@ rpm:
1. Set the decimal point position to 1 decimal places.
2. Using the formula, set the prescale value (α) to
1/N × 60 = 60/5 = 12.

d: Diameter

body (m)
• Observe the following points when
setting a prescale value.
Set the set value to a value less than {Maximum countable value
− Prescale value}.
Example: If the prescale value is 1.25 and the counting range is
0.000 to 999.999, set the set value to a value less than 998.749
(= 999.999 − 1.25).
If the set value is set to a value greater than this, output will not turn
ON.
Note: If the prescale value setting is incorrect, a counting error will
occur. Check that the settings are correct before using this
function.
Auto-zero Time (auto0)
It is possible to make the settings so that the frequency will be forceset to 0 if there is no pulse for a specified period of time. This time is
called the auto-zero time.
Note: Set the auto-zero time to a time slightly longer than the
estimated interval between input pulses. It will not be
possible to make accurate measurements if the auto-zero
time is set to a time shorter than the input pulse cycle.
Setting a time that is too long may also result in problems,
such as a time-lag between rotation stopping and the
alarm turning ON.

H7CX-R@-N
Startup Time (stmr)
Key Protect Level (ypt)
In order to prevent undesired output resulting from unstable input
immediately after the power supply is turned ON, measurement can
be prohibited for a set time at startup.
It can also be used to stop measurement and disable output until the
rotating body reaches the normal rate of rotation, after the power
supply to the H7CX and rotating body are turned ON at the same time.
Set the key protect level.
Refer to Key Protect Level on page page 48.

If the total ON count of the output exceeds the alarm set value, e3
will be displayed on the Timer to indicate that the output ON count
alarm value was exceeded. Refer to Self-diagnostic Function on page
page 48 for information on the e3 display.
ON Count Alarm Set Values for Outputs 1 and 2 (OUT1
and OUT2) (on1a and on2a)
This function records the peak and bottom (i.e., minimum) values
after counting starts (after turning ON the power supply or changing
the configuration selection mode or function setting).
The peak value is also held when the power supply is interrupted.
Set the ON count alarm values for the outputs 1 and 2.
The limit can be set to between 0 × 1000 (0 times) and 9999 × 1000
(9,999,000 times). Only the underlined values are set. The alarm will
be disabled if 0 is set.
If the total ON count of instantaneous output 1 or 2 exceeds the alarm

Safety Precautions for All H7CX Series (Common)
CAUTION
Do not allow pieces of metal, wire clippings, or fine
metallic shavings or fillings from installation to enter
the product. Doing so may occasionally result in
electric shock, fire, or malfunction.
Minor injury due to explosion may occasionally occur.
Do not use the Counter where subject to flammable or
explosive gas.
Fire may occasionally occur. Tighten the terminal
screws to the rated torque.
H7CX terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 N·m)
P2CF Socket terminals: 4.4 lb-in (0.5 N·m)
Minor injury due to electric shock may occasionally
occur. Do not touch any of the terminals while power
is being supplied. Be sure to mount the terminal cover
after wiring.
The life expectancy of the output relay varies
considerably according to its usage. Use the output
relay within its rated load and electrical life
expectancy. If the output relay is used beyond its life
expectancy, its contacts may become fused or there may be a
risk of fire. Also, be sure that the load current does not exceed
the rated load current and when using a heater, be sure to use a
thermal switch in the load circuit.
Minor electric shock, fire, or malfunction may
occasionally occur. Do not disassemble, modify, or
repair the Counter or touch internal components.
Precautions for Safe Use
• The panel surface of the H7CX-A/-R is water-resistant (conforming
to NEMA4, IP66, UL Type 4X (Indoor Use Only). To protect the
internal circuits from water penetration through the space between
the H7CX and operating panel, waterproof packing is included.
Attach the Y92F-30 Adapter with sufficient pressure with the
reinforcing screws so that water does not penetrate the panel.
0.5 to 1 mm
It is recommended that the
space between the screw
head and the Adapter be
0.5 to 1 mm.
• When mounting the Counter to a panel, tighten the two mounting
screws alternately, a little at a time, so as to keep them at an equal
tightness. If the panel screws are tightened unequally, water may
enter the panel.
• Store the Counter at the specified temperature. If the Counter has
been stored at a temperature of less than
−10°C, allow the Counter to stand at room temperature for at least
3 hours before use.
• Mounting the Counter side-by-side may reduce the life
expectancies of internal components.
• Use the Counter within the specified ranges for the ambient
operating temperature and humidity.
• Do not use in the following locations:
• Locations subject to sudden or extreme changes in temperature.
• Locations where high humidity may result in condensation.
• Do not use the Counter outside of the rated ranges for vibration,
shock, water exposure, and oil exposure.
• Do not use this Counter in dusty environments, in locations where
corrosive gasses are present, or in locations subject to direct
sunlight.
• Install the Counter well away from any sources of static electricity,
such as pipes transporting molding materials, powders, or liquids.
52
• Internal elements may be destroyed if a voltage outside the rated
voltage range is applied.
• Be sure that polarity is correct when wiring the terminals.
• Separate the Counter from sources of noise, such as devices with
input signals from power lines carrying noise, and wiring for I/O
signals.
• Do not connect more than two crimp terminals to the same
terminal.
• Up to two wires of the same size and type can be inserted into a
single terminals.
• Use the specified wires for wiring. Applicable Wires: AWG 18 to
AWG 22, solid or twisted, copper
• Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly indicate its
function.
• When the Counter is operated with no-voltage input (NPN input),
approximately 14 V is output from the input terminals. Use a sensor
that contains a diode.
Sensor
Diode
0V
Input
• Use a switch, relay, or other contact so that the rated power supply
voltage will be reached within 0.1 seconds. If the power supply
voltage is not reached quickly enough, the Counter may
malfunction or outputs may be unstable.
• Use a switch, relay, or other contact to turn the power supply OFF
instantaneously. Outputs may malfunction and memory errors may
occur if the power supply voltage is decreased gradually.
• When changing the set value during operation, because the H7CX
uses a constant read-in system, output will turn ON if the set value
is equal to the present value.
• When changing the comparison value during operation, because
the H7CX uses a constant read-in system, the output status will
change if the comparison value is changed to a value on the other
side of the present value. (when using as a tachometer)
• If the set value and present value are both 0, the output will turn
ON for the default setting. The output will turn OFF during a reset
operation. (when using as a counter)
• When the power is turned ON using the factory settings, the output
will turn ON after 999.9 s if no pulses are received as count input.
• Do not use organic solvents (such as paint thinners or benzine),
strong alkali, or strong acids. They will damage the external finish.
• Confirm that indications are working normally, including the
backlight LED, and LCD. The indicator LEDs, LCD, and resin parts
may deteriorate more quickly depending on the application
environment, preventing normal indications. Periodic inspection
and replacement are required.
• The waterproof packing may deteriorate, shrink, or harden
depending on the application environment. Periodic inspection and
replacement are required.
H7CX-@-N
Precautions for Correct Use
• H7CX models with a 12 to 24-VDC power supply use a
transformer-free power supply method in which the power supply
terminals are not isolated from the signal input terminals. If a nonisolating DC power supply is used, unwanted current paths may
occasionally burn or destroy internal components depending on
the wiring. Always check the wiring sufficiently before use.
• An inrush current of approx. 10 A will flow for a short time when the
power supply is turned ON. If the capacity of the power supply is
not sufficient, the Counter may not start. Be sure to use a power
supply with sufficient capacity.
• Maintain voltage fluctuations in the power supply within the
specified operating voltage range.
• When turning the power ON and OFF, input signal reception is
possible, unstable, or impossible as shown in the diagram below.
Power ON
supply OFF
200 ms 0 to 90 ms

Load current (mA)
• Inrush current generated by turning ON or OFF the power supply
may deteriorate contacts on the power supply circuit. Turn ON or
OFF to a device with the rated current of more than 10 A.
• The capacity of the external power supply is 100 mA at 12 V. When
using a 24 VAC/12 to 24 VDC power supply, reduce the load with
the power supply voltage, as shown in the following diagram (DC
power supplies only).
100
• Attach the front panel when using the Counter. The tabs in the
middle of each of four sides secure the front panel to the main
body. To remove the panel, widen the four tabs and pull the panel
toward you.
To mount the panel, fit all four tabs correctly into the grooves on the
main body.

Conformance to EN/IEC Standards
• When conforming to EMC standards, refer to the information
provided in this datasheet for cable selection and other conditions.
• This is a class A product. In residential areas it may cause radio
interference, in which case the user may be required to take
adequate measures to reduce interference.
• H7CX-A@-N: Basic insulation is provided between power supply
and input terminals, between power supply and output terminals,
and between input and output terminals. (However, no insulation is
provided between the power supply and input terminals for the
H7CX-A@D-N.)
• H7CX-R@-N: Basic insulation is provided between power supply
and input terminals and between input and output terminals.
• When double insulation or reinforced insulation is required, apply
double insulation or reinforced insulation as defined in IEC 60664
that is suitable for the maximum operating voltage with clearances
or solid insulation.
• Connect the input and output terminals to devices that do not have
any exposed charged parts.

Power supply voltage (VDC)
• If the prescale value setting is incorrect, a counting error will occur.
Check that the settings are correct before using this function.
• Make sure that all settings are appropriate for the application.
Unexpected operation resulting in property damage or accidents
may occur if the settings are not appropriate.
• Do not leave the Counter for long periods at a high temperature
with output current in the ON state. Doing so may result in the
premature deterioration of internal components (e.g., electrolytic
capacitors).
• EEPROM is used as backup memory when the power is
interrupted. The write life of the EEPROM is 100,000 writes. The
EEPROM is written at the following times:
• When the power supply is turned OFF
• When switching from Configuration Selection Mode or Function
Setting Mode to Run Mode
• Dispose of the product according to local ordinances as they apply.
