Relationship between Input and Power
Supply Circuits (except for H3CR-A8E)
The H3CR-A (except for H3CR-A8E) uses transformerless power
supply. When connecting a relay or transistor as an external signal
input device, pay attention to the following points to prevent shortcircuiting due to a sneak current to the transformerless power supply.
If a relay or transistor is connected to two or more Timers, the input
terminals of those Timers must be wired properly so that they will not
differ in phase, otherwise the terminals will be short-circuited to one
another.

Relationship between Input and Power
Supply Circuits (H3CR-A@/-A@S)
An appropriate input is applied to the input signal terminals of the
H3CR-A@/-A@S when one of the input terminals is short-circuited
with the common terminal (terminal 2) for the input signals. Never
use terminal 10 as the common terminal for this purpose, otherwise
the internal circuit of the Timer will be damaged.
If a relay or transistor is connected to two or more Timers, the input
terminals of those Timers must be wired properly so that they will not
be different in phase or the terminals will be short-circuited to one
another (refer to the figures below).

*1 Power terminal 2 is a common terminal that is also used for the
input signal. Do not use terminal 10 as a common terminal as
this will damage the internal circuitry.
*2 If a relay or other load is connected here, high voltage will be
applied to the input terminal and damage the internal circuitry.
• The transistor output of the H3CR-A@S is isolated from the internal
circuitry by a photocoupler, and can therefore be used either as an
NPN output type or a PNP (equivalent) output type.
Relationship between Input and Power
Supply Circuits (H3CR-AP)
When using the timer in an environment where considerable noise
occurs, keep the input signal source device, timer unit, and wiring as
far away as possible from the source of the noise. It is also
recommended that shielded wire be used for the input signal wiring
as a countermeasure for noise.
Common to All H3CR-A Models
With the H3CR-AP, input wires must be as short as possible. If the
floating capacity of wires exceeds 1,200 pF (approx. 10 m for cables
with 120 pF/m), the operation will be affected. Pay particular
attention when using shielded cables.
The H3CR-A@S transistor output is isolated from the internal
circuitry by a photocoupler. Therefore, either NPN or PNP output is
possible.

circuit
Since the input circuit and the power supply circuit are configured
independently, the input circuit can be turned ON or OFF irrespective
of the ON/OFF state of the power supply.
It must be noted that a voltage equivalent to the power supply voltage
is applied to the input circuit.

• Wide power supply ranges of High Voltage 100 to 240 VAC/100
to 125 VDC and Low Voltage 24 to 48 VAC/12 to 48 VDC.
• ON- and OFF-times can be set independently and so
combinations of long ON- or OFF-time and short OFF- or ONtime settings are possible.
• Twenty-four time ranges from 0.05 s to 300 h depending on the
model to be used.

Safety Precautions (H3CR-H)
Note: The undermentioned is common for all H3CR-H models.
■ Power Supplies
■ Wiring
The H3CR-H has a large inrush current; provide sufficient power
supply capacity. If the power supply capacity is too small, there may
be delays in turning ON the output.
With the H3CR-H@RL, for the power supply of an input device, use an
isolating transformer, of which the primary and secondary windings are
mutually isolated and the secondary winding is not grounded.
The H3CR-H has a high impedance circuit. Therefore, the H3CR-H
may not be reset if the H3CR-H is influenced by inductive voltage. In
order to eliminate any influence of inductive voltage, the wires
connected to the H3CR-H must be as short as possible and should
not be installed alongside power lines. If the H3CR-H is influenced by
inductive voltage that is 30% or more of the rated voltage, connect a
CR filter with a capacitance of approximately 0.1 F and a resistance
of approximately 120 or a bleeder resistor between the power
supply terminals. If there is any residual voltage due to current
leakage, connect a bleeder resistor between the power supply
terminals.

An appropriate input is applied to the input signal terminal of the Timer
when the input terminal for the input signal is short-circuited. Do not
attempt to connect any input terminal to any terminal other than the input
terminal or to apply voltage across other than the specified input
terminals or the internal circuits of the Timer may be damaged.
The H3CR-H@RL uses transformerless power supply. When
connecting a relay or transistor as an external signal input device,
pay attention to the following points to prevent short-circuiting due to
a sneak current to the transformerless power supply.
If input is made simultaneously from one input contact or a transistor
to the H3CR-H and a Timer whose common input terminals are used
as power terminals, such as the H3CR-A, a short-circuit current will
be generated. Either input through isolated contacts, or isolate the
power supply for one of the Timers.

On the H3CR-F@, do not set both the ON set dial and OFF set dial to
the lowest settings. Doing so may damage the contacts.
■ Others
If the H3CR-H is dropped or experiences some other kind of shock,
because a latching relay is used for output, contacts may be reversed

Time Setting Ring/Panel Cover for H3CR-A/-G
There are two types of Panel Covers (Y92P-48GL, and Y92P-48GB),
all of which are available in two colors. Use the most suitable type of
Panel Cover with the design of the scaling plate according to the
application.
To lock the set time, you can lock the setting dial by using a Y92S-27
Setting Ring and a Y92P-48GL/-48GB Panel Cover. This will help to
prevent the set time from being changed accidentally.
To restrict the set time range, you can restrict the rotating range of
the setting dial by using a Y92S-28 Setting Ring and a 92P-48GL/48GB Panel Cover. Use them to restrict the upper and lower limits of
the setting range.
Refer to Using the Time Setting Ring for H3CR-A/-G on page 53 for
the procedure to attach the Setting Ring.
The Flush Mounting Adapter Y92F-70/Y92F-71 for H3CR-G, Y92F73/Y92F-74 for H3CR-A or the Protective Cover cannot be used.
Note: The Time Setting Ring/Panel Cover cannot be used for H3CRF model or H3CR-H model.

Do not use the Timer in the following locations.
•
•
•
•
•
Locations with radical temperature changes.
Locations with high humidity that may result in condensation.
Locations with excessive vibration or shock.
Locations with corrosive gas or dust.
Locations where the Timer is exposed to sprayed water, oil, or
chemicals.
Pay the utmost attention not to make mistakes in polarity when wiring
the Timer.
Do not connect anything to terminals that are not used.
Risk of internal element damage if a voltage that exceeds the rating
is applied.
Using a surge absorber is recommended if surge voltages occur.
Used for general mandatory action precautions for
which there is no specified symbol.
CAUTION
Risk of fire and explosion due to arcing and relay heat
generation that accompanies switching. Do not use in an
environment where flammable or explosive gas is present.
The H3CR series uses a transformer-less power
supply. Exercise full caution as there is a risk of
electrical shock if input terminal is touched when
power voltage is applied.
The H3CR Series uses a transformerless power supply. Do not touch
the input terminals while the supply voltage is applied, otherwise an
electric shock may be received.
Verify that the power and output LEDs (LCD) are operating normally.
In some usage environments, the LEDs/LCD/ resin components may
deteriorate faster than normal, resulting in display failure. Inspect and
replace regularly.
When disposing of this product, follow the procedures for disposal of
industrial waste that apply in your region.
Verify that the product is the desired product before use.
Exercise caution as the outer casing of the timer may be immersed in
organic solvents (thinner, benzene, etc.), strong alkali, or strong
acids.
Precautions for Correct Use
The service life of the output relay varies widely
depending on switching capacity and switching
conditions. Use only within the rated load and
electrical life count, based on actual conditions of use.
Risk of contact sticking and burning if used past the
service life. Always use a load current that does not
exceed the rating, and if a heater is used, use a thermal switch in the
load circuit.
Do not remove the outer casing.
Changing the Setting
Do not change the time unit, time range, or operation mode while the
Timer is in operation, otherwise the Timer may malfunction.
The time unit and time range can be set with the respective selectors
turned clockwise or counterclockwise.
The selectors are of notched so that they will snap when they are
properly set. Do not set the selectors midway between notches,
otherwise the Timer may break or malfunction.
Do not use H3CR-A models (except for H3CR-A@S) in flicker mode
at the lowest selector setting, or H3CR-F models at the lowest
selector setting. Doing so may result in damage to contacts.

H3CR
Power Supplies
Others
A DC power supply can be connected if its ripple factor is 20% or
less and the mean voltage is within the rated operating voltage range
of the Timer.
If the Timer is mounted to a control board, dismount the Timer from
the control board or short-circuit the control board circuitry before
carrying out a voltage withstand test between the electric circuitry
and non-charged metal part of the Timer. This protects the internal
circuitry of the Timer from damage.
An AC power supply can be connected to the power input terminals
without regard to polarity. A DC power supply must be connected to
the power input terminals as designated according to the polarity of
the terminals.
Make sure that the voltage is applied within the specified range,
otherwise the internal elements of the Timer may be damaged.
Connect the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value at once, otherwise the
Timer may not be reset or a timer error may result.
Be aware that the operating voltage will rise by 5% if the rated
voltage is applied to the Timer continuously while the ambient
temperature is close to the maximum permissible ambient
temperature.
The power supply circuit of any H3CR-A model (except for H3CRA@S), H3CR-F 100-to-240-VAC model, and H3CR-G model is a
switching circuit. If the power line connected to the power supply
circuit has a transformer with high inductance, a counterelectromotive voltage will be induced by the inductance. To suppress
the voltage, apply a CR filter to the power supply line.
Apply the power voltage at once through the switch and relay
contacts. If not applied at once, power reset may not take place or
time-up may occur.
When the power is turned on, a rush current (refer to your OMRON
website) may flow briefly and the timer may not start if there is
insufficient power capacity. Use a power supply with sufficient
capacity.
If the timer is left for an extended time at high temperature in the
time-up state (internal relay ON), the internal components
(electrolytic capacitors, etc.) may deteriorate faster than normal. For
this reason, use in combination with a relay, and avoid leaving in the
time-up state for an extended time (for example, one month or
longer).

Mounting Direction
There are no restrictions to the mounting direction.
Precautions for EN61812-1
Conformance
The H3CR Series as a built-in timer conforms to EN61812-1
provided that the following conditions are satisfied.
Make sure that no voltage is applied to any terminals before
dismounting the Timer from the Socket.
The output section of the H3CR is provided only with basic isolation.
The H3CR itself is designed under the following conditions:
• Overvoltage category III
• Pollution degree 2
• Isolation
Operation parts: Reinforced isolation
With clearance of 5.5 mm and creepage distance of 5.5 mm at
230 VAC
Output: Basic isolation (See note)
With clearance of 3 mm and creepage distance of 3 mm at
230 VAC
Note: The 11-pin model ensures basic isolation by itself and also
ensures basic isolation with the 11-pin model mounted to the
OMRON P2CF-11-@ or P3GA-11 Socket.
Connect the two output contacts different in polarity to the loads so
that they will be the same in potential.

BUYER ACKNOWLEDGES THAT IT ALONE HAS DETERMINED THAT THE
PRODUCTS WILL SUITABLY MEET THE REQUIREMENTS OF THEIR
INTENDED USE. Omron further disclaims all warranties and responsibility of
any type for claims or expenses based on infringement by the Products or otherwise of any intellectual property right. (c) Buyer Remedy. Omron’s sole obligation hereunder shall be, at Omron’s election, to (i) replace (in the form
originally shipped with Buyer responsible for labor charges for removal or
replacement thereof) the non-complying Product, (ii) repair the non-complying
Product, or (iii) repay or credit Buyer an amount equal to the purchase price of
the non-complying Product; provided that in no event shall Omron be responsible for warranty, repair, indemnity or any other claims or expenses regarding
the Products unless Omron’s analysis confirms that the Products were properly handled, stored, installed and maintained and not subject to contamination, abuse, misuse or inappropriate modification. Return of any Products by
Buyer must be approved in writing by Omron before shipment. Omron Companies shall not be liable for the suitability or unsuitability or the results from the
use of Products in combination with any electrical or electronic components,
circuits, system assemblies or any other materials or substances or environments. Any advice, recommendations or information given orally or in writing,
are not to be construed as an amendment or addition to the above warranty.
See http://www.omron247.com or contact your Omron representative for published information.
Limitation on Liability; Etc. OMRON COMPANIES SHALL NOT BE LIABLE
FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES,
LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY
WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS
BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY.
Further, in no event shall liability of Omron Companies exceed the individual
price of the Product on which liability is asserted.
Indemnities. Buyer shall indemnify and hold harmless Omron Companies and
their employees from and against all liabilities, losses, claims, costs and
expenses (including attorney's fees and expenses) related to any claim, investigation, litigation or proceeding (whether or not Omron is a party) which arises
or is alleged to arise from Buyer's acts or omissions under these Terms or in
any way with respect to the Products. Without limiting the foregoing, Buyer (at
its own expense) shall indemnify and hold harmless Omron and defend or settle any action brought against such Companies to the extent based on a claim
that any Product made to Buyer specifications infringed intellectual property
rights of another party.
Property; Confidentiality. Any intellectual property in the Products is the exclusive property of Omron Companies and Buyer shall not attempt to duplicate it
in any way without the written permission of Omron. Notwithstanding any
charges to Buyer for engineering or tooling, all engineering and tooling shall
remain the exclusive property of Omron. All information and materials supplied
by Omron to Buyer relating to the Products are confidential and proprietary,
and Buyer shall limit distribution thereof to its trusted employees and strictly
prevent disclosure to any third party.
Export Controls. Buyer shall comply with all applicable laws, regulations and
licenses regarding (i) export of products or information; (iii) sale of products to
“forbidden” or other proscribed persons; and (ii) disclosure to non-citizens of
regulated technology or information.
Miscellaneous. (a) Waiver. No failure or delay by Omron in exercising any right
and no course of dealing between Buyer and Omron shall operate as a waiver
of rights by Omron. (b) Assignment. Buyer may not assign its rights hereunder
without Omron's written consent. (c) Law. These Terms are governed by the
law of the jurisdiction of the home office of the Omron company from which
Buyer is purchasing the Products (without regard to conflict of law principles). (d) Amendment. These Terms constitute the entire agreement between
Buyer and Omron relating to the Products, and no provision may be changed
or waived unless in writing signed by the parties. (e) Severability. If any provision hereof is rendered ineffective or invalid, such provision shall not invalidate
any other provision. (f) Setoff. Buyer shall have no right to set off any amounts
against the amount owing in respect of this invoice. (g) Definitions. As used
herein, “including” means “including without limitation”; and “Omron Companies” (or similar words) mean Omron Corporation and any direct or indirect
subsidiary or affiliate thereof.
Certain Precautions on Specifications and Use
1. Suitability of Use. Omron Companies shall not be responsible for conformity
with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron will provide applicable third party certification documents identifying
ratings and limitations of use which apply to the Product. This information by
itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application
or use. Buyer shall be solely responsible for determining appropriateness of
the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equipment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or property. Please know and observe all prohibitions of use applicable to this Product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT

OVERALL EQUIPMENT OR SYSTEM.
Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Omron’s representative at any time
to confirm actual specifications of purchased Product.
Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors or omissions.
