DIN 48 × 48-mm Twin Timers
• Wide power supply ranges of 100 to 240 VAC and 48 to
125 VDC respectively.
• ON- and OFF-times can be set independently and so
combinations of long ON- or OFF-time and short OFF- or ON-
time settings are possible.
• Fourteen time ranges from 0.05 s to 30 h or from 1.2 s to 300 h
depending on the model to be used.
• Models with a flicker ON start or flicker OFF start are available.
• Easy sequence checks through instantaneous outputs for a
zero set value at any time range.
• Length, when panel-mounted with a Socket, of 80 mm or less.
• 11-pin and 8-pin models are available.

H3CR-H
Safety Precautions (H3CR-H)
Note: The undermentioned is common for all H3CR-H models.
■ Power Supplies
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.
■ Wiring
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 μF and a resistance
of approximately 120 Ω 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.
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.

■ Operation

An interval of 3 s minimum is required to turn on the H3CR-H after
the H3CR-H is turned off. If the H3CR-H is turned on and off
repeatedly with an interval of shorter than 3 s, abnormal heating or
burning may occur in internal elements.

After the forced reset function of the H3CR-H is activated, an interval
of 3 s minimum is required to activate the forced reset function again.
If the forced reset function is activated repeatedly with an interval of
shorter than 3 s, the internal parts of the H3CR-H may deteriorate
and the H3CR-H may malfunction.

■ Input/Output (H3CR-H@RL)
Reset
input
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.
Output
If it is required that the output be turned on repeatedly with an
interval of shorter than 3 s, consider use of the H3CR-A in mode D
(signal OFF-delay).
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.
■ 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
or go into a neutral state. If the H3CR-H is dropped, reconfirm correct
operation.
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.

Safety Precautions for All Timers
Refer to the Safety Precautions for individual Timers for precautions specific to each Timer.
• Normal operation may not be possible in locations subject to
!WARNING
sulfidizing gas, such as in sewer systems or waste incinerators.
OMRON does not market any Timers or other control devices for
operation in atmospheres containing sulfidizing gas. Seal the Timer
so that sulfidizing gas will not enter it. If sealing is not possible,
OMRON does provide special Timers with improved resistance to
sulfidizing gas. Ask your OMRON representative for details.
The following Timers contain lithium batteries that are
not explosion proof.
1. Timers with Built-in Batteries: H5L
The Timer contains a lithium battery, which may occasionally
ignite or rupture. Do not disassemble, deform under pressure,
heat to 100°C or higher, or incinerate the Timer.
Power Supply
• Be sure that the voltage applied is within the specified range,
2. Timers with Replaceable Batteries: Y92S-20 (for H5CN-M)
The battery may occasionally rupture, ignite, or leak fluid. Do
not short the positive and negative terminals. Do not charge,
disassemble, deform under pressure, or throw the battery into a
fire. If a non-specified battery is used, the battery may leak fluid
or rupture, occasionally resulting in equipment failure or minor
injury. Use only the specified battery.
otherwise the internal elements of the Timer may be damaged.
• Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly indicate its
function.
• Maintain voltage fluctuations
in the power supply within
the specified range.
Allowable
Voltage Range
!CAUTION
The following Timers contain lithium batteries that are
explosion proof.
• Use a commercial power supply for the power supply voltage input
to models with AC inputs.
Inverters with an output frequency of 50/60 Hz are available, but
the rise in the internal temperature of the Timer may result in
ignition or burning. Do not use an inverter output for the power
supply of the Timer.
• The Timers listed below cannot be directly turned ON and OFF by
using an AC 2-wire proximity sensor to turn the Timer's power
supply ON and OFF.
Timers with Built-in Batteries:H5BR, H5AN-4DM, H5S, H5F, and
H4KV
The Timer contains a lithium battery, which may occasionally
ignite or rupture. Do not disassemble, deform under pressure,
heat to 100°C or higher, or incinerate the Timer.
Use the following countermeasure when using an AC 2-wire
proximity sensor with the Timer. (The power supply circuit in the
Timer uses half-wave rectification. Only a half AC wave is supplied
to the proximity sensor, which may cause operation to be unstable.)
■ Precautions for Safe Use
Operating Environment
Applicable Models
H3Y, H3YN, H3RN, H3CA-8, RD2P, and H3CR(-A, -A8, -AP, -F, and
-G)
• Use the Timer within the ratings specified for ambient operating
temperature and ambient operating humidity for each model.
• Store the Timer with the specified temperature range for each
model. If the Timer has been stored at a temperature of less than
−10°C, allow the Timer to stand at room temperature for at least 3
hours before using it.
Countermeasure
Wire through a relay and use the relay contacts to turn the power
supply ON and OFF.
Confirm the stability of operation after making the connections.
• Use the Timer within the performance specified for water and oil
exposure for each model.
• Install protective measures (such as earth leakage breakers, wiring
breakers, or fuses) on the power supply side according to any
applicable laws or regulations.
• Do not use the Timer in locations subject to shock and vibration.
Long-term usage in such locations may damage the Timer due to
stress.
Magnetic contactors generate a shock of 1,000 to 2,000 m/s2 when
switching a load. When mounting to DIN Track, separate magnetic
contactors from the Timer so that the Timer is not subjected to
vibration and shock. Use anti-vibration rubber.
• Do not use the Timer in locations subject to excessive dust,
corrosive gases, or direct sunlight.
• Do not use organic solvents (such as paint thinner or benzine),
strong alkalis, or strong acids because they will damage the
external finish of the Timer.
• Separate the input devices, input wiring, and Timer as far as
possible from sources of noise and power lines carrying noise.
• When using the Timer in environments subject to large amounts of
static electricity (e.g., pipes carrying molding materials, powders, or
fluid materials), separate the Timer as far as possible from the
sources of static electricity.
• Do not remove the external case from the Timer.
• Do not use the Timer in locations where condensation may occur
due to high humidity or sudden temperature changes.
Condensation inside the Timer may result in malfunction or
damage to Timer elements.
• The life of internal parts may be reduced if Timers are mounted in
close proximity to each other.
• Resin and rubber parts (e.g., rubber packing) may deteriorate,
shrink, or harden depending on the operating environment (e.g.,
subjected to corrosive gases, ultraviolet light, or high
temperatures). We recommend periodic inspection and
replacement.

Correctly Handling Input Signals
Other Precautions
• Confirm that you have the correct model before using it.
Malfunction due to noise may occur if input wiring is placed in the
same duct or conduit as power lines or high-voltage lines. Separate
input wiring from power lines and wire them in a separate system.
Also, use shielded cables, use metal conduits, and keep wiring
distances as short as possible.
• Be sure that all terminals are wired correctly.
• Always test the output status with a tester before using a Timer with
a built-in keep relay (e.g., the H3CR-H and H3DE-H). Shock
resulting from dropping the Timer during transport or handling may
cause the output contacts to reverse or to be in a neutral status.
• Leaving the Timer with outputs ON at a high temperature for a long
time may hasten the degradation of internal parts (such as
electrolytic capacitors). Use the Timer in combination with relays
and avoid leaving the Timer with the output turned ON for an
extended period of time (e.g., for more than a month).
Timers with Relays
• Do not connect a load that exceeds contact ratings, such as the
switching capacity (contact voltage or contact current). Insulation
faults, contact welding, contact faults, and other failures to achieve
specified performance may occur and the relay may be damaged or
may burn.
Reference Example (Use the Timer as shown below.)
• Continued use with deteriorated performance may ultimately result
in insulation breakdown between circuits or relay burning. The life
of the built-in relay is greatly affected by switching conditions.
Before using the Timer, test operation under actual application
conditions and confirm that the switching frequency presents no
problems in performance.

• Electrical life depends on the type of load, switching frequency, and
ambient environment. Observe the following precautions when
using the Timer. When switching a DC load, contact transfer may
cause the contacts to stick or may cause contact failure. Confirm
applicability and consider using a surge absorbing element. When
switching at high frequencies, heat generated by arcing may cause
contacts to melt or may cause metal corrosion. Consider
connecting an arc absorbing element, reducing the switching
frequency, or lowering the humidity.
• Be sure that only a qualified worker (e.g., an electrical engineer)
performs electrical work for the Timer.
• The surge current depends on the type of load, which also affects
contact switching frequency and the number of operations. Check
the rated current and the surge current, and design the circuits with
sufficient margin.

• Arcing when switching and relay heating may result in ignition or
explosion. Do not use the Timer in atmospheres subject to
inflammable or explosive gases.
• Contact faults may occur. Do not use the Timer in atmospheres
subject to sulfidizing gas, chloride gas, or silicon gas.
• The switching capacity for DC voltage loads is lower than that for
AC voltage loads.
Timers with Non-contact Outputs
• Short faults or open faults may occur due to destruction of the
output element. Do not use the Timer for a load that exceeds the
rated output current.
• Short faults or open faults may occur due to destruction of the
output element from reverse electromotive force. When using the
Timer for a DC inductive load, always connect a diode as a
countermeasure against reverse electromotive force.
