The 10-point model has a normal I/O delay time of 19.2 m (typical); 10-point models with short I/O delay time are not available.
The transmission signals of the 16-point PLC connector model are not compatible with those of the 10-point model. Therefore
16-point PLC connector models and 10-point models cannot be used in combination.

Note:
1. The transmission distance values stated in this table are possible if the Input or Output Link Terminal is connected to an independent
power supply. If a single power supply is connected to the Input or Output Link Terminal, the supply voltage must be 24 VDC ±10%,
in which case the transmission distance of a normal-speed model is 100 m maximum and that of a high-speed model is 50 m maximum. Refer to Power Supply on page 21 for details.
2. A shielded transmission cable or a VCTF cable with a thickness of 0.75 mm2 minimum must be used for signal transmission. If the
VCTF cable is used, however, the transmission distance will be 10 m maximum regardless of whether or not independent power
supplies for the Input and the Output Link Terminals are used.
3. The minimum input time is required for the B7A/B7AS to read an input signal.
4. For high-speed models, these values are possible without grounding the shielded line.

Note:
1. If there is a possibility of noise interference from the power supply, input, and/or output lines, add appropriate noise protection circuits. Refer to Noise Protection Circuits on page 101 for details.
2. The transmission distance values stated in this table are possible if the Input or Output Link Terminal is connected to an independent
power supply. If a single power supply is connected to the Input or Output Link Terminal, the supply voltage must be 24 VDC ±10%,
in which case the transmission distance of a normal-speed model is 100 m maximum and that of a high-speed model is 50 m maximum. Refer to Power Supply on page 36 for details.
3. A shielded transmission cable or a VCTF cable with a thickness of 0.75 mm2 minimum must be used for signal transmission. If the
VCTF cable is used, however, the transmission distance will be 10 m maximum regardless of whether or not independent power
supplies for the Input and the Output Link Terminals are used.
4. The minimum input time is required for the B7A to read an input signal.
5. Set the timer of the PLC to 0.02 s minimum if a normal-speed model is connected to the PLC.
6. For high-speed models, these values are possible without grounding the shielded line.

Be sure to turn the power OFF before performing wiring. Do not
touch the terminal block while power is supplied unless the cover is
mounted. Doing so may result in electric shock.
Be sure to apply the specified voltage to input terminals. Applying an
incorrect voltage may prevent the product from operating with its
rated performance characteristics, or may cause damage or burning.
Relay Models
Do not use the product for loads that exceed the rated values for
switching capacity (e.g., switching voltage and switching current). If
the ratings are exceeded the product may not be able to operate
with its rated performance characteristics due to factors such as
insulation failure, contact failure, or contact welding. It may even
result in damage to or burning of the relay.
The lifetime of relays varies significantly with the switching conditions. Be sure to confirm the required performance characteristics
by testing the relay under actual operating conditions, and use the
relay at a frequency at which it can perform with the required performance characteristics. Continued use of the relay in a state where it
cannot maintain the rated characteristics may eventually result in
damage to the insulation between circuits or burning of the relay.
Do not use the product in locations subject to flammable or explosive gases. Doing so may result in fire or explosion due to the arcing
that accompanies the switching mechanism and heating up of the
relay.
No-contact Output (Transistor, Power MOS FET Relay, and
SSR Output)
Do not use the product for loads that exceed the rated output current. Doing so may damage output elements and result in short-circuiting or open circuits.
When using the product for DC inductive loads, connect a diode that
will prevent reverse voltages. Not doing so may damage output elements and result in short-circuiting or open circuits.
Correct Use
Link Terminals with Relay Outputs
This Link Terminal is for relay output.
G70D-R6Rj1-B7A Link Terminals use 24-VDC G6D-1A Relays
and G70D-R6Mj1-B7A Link Terminals use 24-VDC G3DZ-2R6PL
Relays.
When replacing relays, use the yellow Relay Removal Tool at the
corner of the screw terminal (except for G7TC).
Do not mount or dismount relays with the power supplied.
Opening the Front Cover (Rotating Type):
Hold the two bottom corners of the front cover (labelled A in the diagram below), and lift upwards to open.

may result in electric shock or malfunction.
When replacing relays, use the yellow Relay Removal Tool at the
corner of the screw terminal (except for G7TC).
Relays must be inserted vertically so that the legs do not bend. Not
inserting relays properly may result in malfunction or heating.
Wiring
Be sure that terminal polarity, wiring between the transmission lines
and power supply, and the voltage specifications for I/O power supplies are correct.
Do not mount or remove connectors with the power supplied. Doing
so may result in malfunction.
Locks for Connecting Cables
Ensure that the connectors for connecting cables are securely
locked before supplying power.

Note:
1. The transmission distance values stated in this table are possible if the Input or Output Link Terminal is connected to an independent
power supply. If a single power supply is connected to the Input or Output Link Terminal, the supply voltage must be 24 VDC ±10%,
in which case the transmission distance of a normal-speed model is 100 m maximum and that of a high-speed model is 50 m maximum. Refer to Power Supply on page 68 for details.
2. A shielded transmission cable or a VCTF cable with a thickness of 0.75 mm2 minimum must be used for signal transmission. If the
VCTF cable is used, however, the transmission distance will be 10 m maximum regardless of whether or not independent power
supplies for the Input and the Output Link Terminals are used.
3. The minimum input time is required for the B7AH to read an input signal.
4. This is the value for the inductive noise on the transmission line measured using a noise tester. For high-speed models, it is the
value without the shield line connected to ground.

Precautions
General
Common Precautions
The B7AH performs 1-to-1 communications and does not require a
communications master. It cannot be connected to CompoBus/S
transmission paths from OMRON remote masters.
Do not use the B7AH in locations subject to corrosive gases.
When using the B7AH in locations where a large amount of static
electricity is generated (e.g., molding materials, powder, or fluid
materials conveyed along pipelines), install the B7AH at least 1 m
away from the source of the static electricity.
Line Resistance in the Transmission Path
If power and signals are transmitted together along 3-core cable,
ensure that the line resistance in the transmission path between
Link Terminals is less than 2.5 Ω. (The same value applies even if
terminal blocks, connectors, or slip rings are used at points on the
line.) If the line resistance rises to a value greater than this, the current flowing to 0 V and the line resistance will cause a large voltage
drop, preventing normal transmission and generating an error. As a
rough guide, the line resistance with a VCTF cable of thickness
0.75 mm2 will be 2.5 Ω per 100 m.
Connection to 10-point B7A Terminals is not possible because
transmission signals are not compatible.
If there is a possibility of shocks or vibration, prevent the pins being
damaged by securing the Link Terminal to the PCB using an (e.g.,
epoxy-based) adhesive.
Do not touch the pins. Doing so may cause deformation. In addition,
touching the pins in an ungrounded state may result in damage to
internal elements due to static discharge. Use an anti-static mat during work to ensure that the body is in a grounded state.
Soldering
When soldering using a soldering iron or a soldering bath, solder in
less than 5 s at a temperature not exceeding 260°C. Do not use
reflow soldering.
Cleaning
Do not use highly acidic or highly alkaline solvents to clean the PCB.
Power Supply
Be sure to use the specified power supply voltage. Do not use a
power supply that has a large ripple or intermittently generates
abnormal voltages.
Noise and Miswiring Protection Circuits
If there is a possibility of noise interference between the power supply pins (+V and –V or VDD and VSS) or at input or output pins (IN00
to IN15 or OUT00 to OUT15), or if there is a possibility of miswiring
the signal pin (SIG) and the positive power supply pin (+V or VDD),
include the protection circuits described on page 68.
Wiring
Do not wire transmission lines parallel to, and less than 10 cm away
from, lines carrying high voltages or currents. If transmission lines
are installed less than 10 cm away from potential sources of noise,
confirm that correct operation is possible before using the Link Terminal in actual operation.
Do not perform wiring with the power supply turned ON. Doing so
may cause pins to be accidentally short-circuited, resulting in damage to internal elements and communications failure.
If the SIG pin and the positive power supply pin or the VDD (+5 V)
pin are shorted during communications, the Link Terminal will malfunction and normal communications will not be possible. Confirm
that power lines are not shorted before turning ON the power.
Be sure to apply the specified power supply to the power supply pins
(positive, negative, VDD, and VSS). Applying excessive voltages
(e.g., 100 VAC) will cause the Link Terminal to malfunction and normal communications will not be possible.
Shorting (no-load state) the OUT pins of Output Link Terminals during communications will cause the Link Terminal to malfunction. Be
sure to connect a load within the specified load current range. When
measuring the current with a tester, measure with the load supplied.
Recommended Cables
Normal-speed Models
Cabtire Cables
With a single power supply connected to Input or Output Link Terminal:
0.75-mm2 VCTF cable × 3
With independent power supplies connected:
0.75-mm2 VCTF cable × 2
The following cables can also be used:
Twisted-pair Cables
(If only a single power supply is used, a conductor of thickness
0.75-mm2 min. is required.)
Transmission distance: 100 m max.
High-speed Models
Shielded Cables
Use cables for which the cross-sectional area of the conductor is at
least 0.75 mm2.

Operation
Note: The undermentioned is common for all B7A-series Link Terminals.
Connection of B7A and Programmable Controller
Each terminal of the B7A should be used for only single signal transmission without a transmission host. Therefore the B7A cannot be connected to OMRON’s SYSMAC BUS Remote I/O System. To transmit signals from the B7A to a PLC, connect the B7A’s terminals to an I/O Unit
mounted on the PLC.
Refer to B7A-series Models with PLC Connectors and Connecting PLCs on page 39 for details.

Peripheral Circuits of Modular Model
Input Interface Circuit
The modular model has a minimum ON discrimination voltage of 2.2
V and a maximum OFF discrimination voltage of 0.8 V, which are
suitable for TTL circuits. If sensors are used for input, the following
input circuits are required.
Two-wire DC Sensor Input
If a two-wire DC sensor is used for input, current limit resistor R1 and
leakage current diverter R2 are required as shown in the diagram
below. The following table lists R1 and R2 values for the E2E-XD-N
Two-wire DC Proximity Sensor (with a current leakage of 0.8 mA
maximum, a residual voltage of 3 V maximum, and a minimum control output current of 3 mA).
Input with B7A and Common Power Supply
(12 to 24 VDC) (10-point Modular Model only)
The 10-point modular model has an input voltage range of 0 to 5
VDC. If a common power supply is connected, current limit resistor
R3 is required as shown in the diagram below. Use the following formula to calculate the value of R3.
R3 =

Transmission Errors and Output Signals
Transmission errors occur in the following cases:
•
•
•
•
When the signal or 0-V wire is disconnected.
When the signal is influenced by high-level external noise or the
signal is excessively deformed because the length of the
transmission path is more than the permissible distance.
When the supply voltage to the Link Terminals are not within the
operating voltage range (12 to 24 V ±10%).
Immediately after the Link Terminals are turned on.
(An error is reset within 300 ms after the power is turned on.)
Output Signals
HOLD: When an error occurs, the output signals just before the occurrence of the error will be maintained.
LOAD OFF: When an error occurs, all output signals will be turned
OFF.
Automatic Reset
When the error is corrected, the Link Terminals will automatically reset themselves.

Precautions
Note: The undermentioned is common for all B7A-series Link Terminals.
General
Modular Models
Each terminal of the B7A-series should be used for only single signal transmission without a transmission host. The B7A-series cannot be connected to OMRON’s SYSMAC BUS Remote I/O System.
Avoid places subject to corrosive gasses or continual shock and/or
vibration.
If high-level electrostatic discharge is generated at the installation
site (e.g., for transfer of a molding material, powder, or liquid through
a pipe), separate the Link Terminals as far as possible from the
source of the electrostatic discharge.
If the Input and Output Terminals are connected via a three-conductor cable to transmit signals with a single power supply (i.e., the
power supply is connected directly to one of the Link Terminals and
indirectly to the other), the transmission distance greatly varies with
the diameter of the cable. This is due to the potential difference between the current on the 0-V transmission wire and on the 0-V I/O
transmission line caused by the resistance of the cable. By increasing the diameter of the cable (decreasing its resistance), the transmission distance can be increased. By reducing the resistance of
the transmission path to 2.5 Ω or less for example (i.e., increasing
the thickness of the wire to 1.25 mm2 or more), a transmission distance of 160 m will be achieved.
It is recommended that a switch for minute loads be connected to
the 16-point screw terminal model because there is a contact input
current of only 3 to 6 mA to the model from the connected switch or
relay.
The Output Terminal has an error of 300 ms maximum after the Output Terminal is turned on. The user should be well aware of this before using error outputs.
Note: The 10-point and 16-point models cannot be connected to
each other because their transmission signal data formats
are not compatible.
Soldering (with an soldering iron or in a soldering tab) must be completed within 5 s at a temperature of 260°C or less.
The supply voltage must be within the operating voltage range. Do
not use a power supply which generates irregular voltages or large
ripples.
Do not apply a strong acidic or alkaline solvent to the printed circuit
board for removal of the flux. The module of the B7A 10-point model
is not of closed-mold construction. The solvent must not remain on
the bottom of the module after the module is cleaned. The module of
the B7A 16-point model is of closed-mold construction.
The input and output circuits are not insulated. If Link Terminals are
influenced by external noise, use photocouplers to insulate the I/O
circuits.
Screw Terminal Models
Apply a torque of 0.78 to 1.18 N S m to tighten wiring terminals.
Hold both edges of the terminal cover to open it.
If the Input or Output Terminal is mounted to a panel with screws,
apply a torque of 0.59 to 0.98 N S m to tighten the screws.
Terminals with PLC Connector Models
Apply a torque of 0.78 to 1.18 N S m to tighten wiring terminals.
Be sure to disconnect the connector unit from the PLC’s I/O connector unit when wiring the screw terminals in order not to impose excessive force on the PLC’s I/O connector unit.
Use the B7A in combination with a PLC correctly, otherwise the B7A
may be damaged. The following are correct combinations.
B7A Input Unit and PLC Output Unit
B7A Output Unit and PLC Input Unit
Wiring
Separate the transmission lines from high voltage or power lines as
far away as possible and do not wire the transmission lines in parallel with high voltage or power lines. If Link Terminals are used near a
device that generates noise, make sure that the Link Terminals do
not malfunction due to the noise generated from the device.
Make sure to turn off the Link Terminals while wiring in order to avoid
a short-circuiting accident that may damage the internal element(s)
of the Link Terminals.
Link Terminals will malfunction if the SIG terminal is short-circuited
with one of the power terminals or Bjj terminal. Before turning the
power on, make sure that the SIG terminal is not short-circuited with
these terminals.
Before checking the insulation resistance of the transmission path,
disconnect the wires from the Link Terminals.
If the OUT terminal and positive power terminal of the Output Link
Terminal is short-circuited during signal transmission, the Link Terminal will malfunction. Apply an appropriate load between these terminals.
When measuring the current, use a multimeter without disconnecting the load.

Precautions
General Precautions
Be careful when touching the B7AP-S1 Power Coupler during operation because the surface temperature of the B7AP-S1 Power
Coupler will rise approximately 20°C after the B7AP-S1 Power Coupler starts power transmission. The surface temperature varies with
the load of the sensing device connected to the B7AP-M1 Power
Coupler and the transmission distance.
Do not subject the head of the B7AP-S1 or B7AP-M1 Power Coupler to excessive shock with hard objects.
Correct Use
Handling
Use the B7AP-S1 and B7AP-M1 Power Couplers with the available
B7A Link Terminals. Refer to page 21, B7A Models.
The M7E-12jj Display Unit, M7E-20jj Display Unit, and B7A
Link Terminals with an I/O delay time of 3 ms cannot be used with the
B7AP-S1 or B7AP-M1 Power Coupler.
Use the LOAD-OFF model for the B7A Output Unit to be connected
to the B7AP-S1. When using a model that allows selection of error
processing, set to the LOAD-OFF mode. This turns OFF signals
right before an occurrence of a transmission error and prevents unexpected signal transmission when the transmission error is
cleared.
Separate the Power Couplers 8±1.5 mm min. away from each other.
The distance between the Power Couplers on standby must be 30
mm or more.
30 mm min.
Do not use the B7AP-S1 or B7AP-M1 Power Coupler outdoors unless it is properly protected.
The B7AP-S1 and B7AP-M1 Power Couplers are products meeting
the requirements of IP67. The B7AP-S1 or B7AP-M1 Power Coupler cannot be, however, used in water or oil.
Keep the heads of the B7AP-S1 and B7AP-M1 Power Couplers free
from dust, otherwise improper signal or power transmission may result between the Power Couplers.
Mounting
Do not supply power to the B7AP-S1 or B7AP-M1 Power Coupler
while connecting the Power Couplers to the B7A Link Terminals.
Connect the Power Couplers to the B7A Link Terminals correctly,
otherwise the internal circuits of the Power Couplers may be damaged.
The SIG terminal must not contact with the power supply terminals,
otherwise the internal elements may be damaged and normal transmission may not be possible.
Use nuts and serrated toothed washers and tighten the nuts to
mount the B7AP-S1 and B7AP-M1 Power Couplers. The tightening
torque applied to each of the nuts must be 39 N S m maximum. The
mounting position will change and improper signal or power transmission may result between the Power Couplers if the nuts are not
tightened properly.
