Safety Precautions
● Refer to Safety Precautions for All Timers.
Note: The following is common for all H3DK models.
Caution
Switching arcs or relay heating may cause fire or
explosion. Do not use the Timer in the presence of
inflammable or explosive gases.
The H3DK Series uses a transformerless power
supply system. An electrical shock may occur if
an input terminal is touched while power is being
supplied.
The inrush current will depend on the type of load
and may influence the contact switching frequency and number of operations. Check both the
rated current and the inrush current, and allow
leeway in the circuit design.
The life of the output relay largely depends on the
switching current and other switch conditions.
Consider the actual application conditions and do
not exceed the rated load or electrical life. If the
output relay is used beyond its service life, the contacts
may fuse or burning may occur. Also, never exceed the
rated load current. When using a heater, also place a thermal switch in the load circuit.
Do not remove the external case.
Minor electric shock, fire, or equipment failure
may sometimes occur. Do not disassemble, modify, or repair the Timer or touch any internal parts.
Precautions for Safe Use
• Use ferrules to wire the H3DK. If stranded wires are used, wire
scraps may enter the Timer, possibly shorting the circuits.
• Rapid changes in temperature or high humidity may cause
condensation in Timer circuits, possibly resulting in malfunction or damage to components. Check the application environment.
• Store the Timer within the rated ranges given for the Timer
model you are using. If the Timer is stored below −20°C, allow
it to warm up for three hours at room temperature before turning ON the power supply.
• Use the Timer within the ambient operating temperature and
ambient operating humidity ranges given for the Timer model
you are using.
• Use the Time within the characteristics for water and oil exposure given for the Timer model you are using.
• Do not use the Timer in locations subject to excessive dust,
corrosive gas, or direct sunlight.
• Do not use the Timer in locations subject to vibration and
shock. Long-term exposure may damage the Timer due to
stress.
• Separate the Timer from any sources of excessive static electricity, such as forming materials and pipes carrying power or
liquid materials.
• Maintain the variations in the power supply voltage to within
the specified allowable range.
• If a voltage that exceeds the rating is applied, internal components may be destroyed.
• Wire all terminals correctly.
• Use only the specified wires for wiring.
Applicable wire gauge: AWG18 to AWG22
• Install and clearly label a switch or circuit breaker so that the
operator can quickly turn OFF the power supply.
• If the Timer is left in the timed out condition for a long period of
time at high temperatures, internal components (such as electrolytic capacitors) may deteriorate quickly.
• The exterior of the Timer may be damaged by organic solvents
(such as thinners or benzene), strong alkali, or strong acids.
• For Timers with AC power input, use a commercial power supply for the power supply voltage. Although some inverters give
50/60 Hz as the output frequency, do not use an inverter output as the power supply for a Timer. Doing so may result in
smoking or burning due to internal temperature increases in
the Timer.
• Use the same type of wiring for all Timer wiring.
• When disposing of the Timer, observe all local ordinances as
they apply.
• The Timer may not operate properly in locations that are subject to sulfide gas, such as in sewers or incinerators. Products
that are suitable for operation in sulfide gas are not available
for OMRON Timers or general control devices. Seal the Timer
to isolate it from sulfide gas. If the Timer cannot be sealed,
OMRON can make special products with resistance to sulfide
gas for some Timers. Ask your OMRON representative for
details.
• Confirm that the power and output indicators are operating
normally. Depending on the operating environment, the indicators and plastic parts may deteriorate faster than expected,
causing the indicators to fail. Periodically perform inspections
and replacements.

Precautions for Correct Use
● Changing Switch Settings
Do not change the time unit, time scale, operating mode, or INIT/
TIME switch while the Timer is in operation. Doing so may result
in malfunction. Turn OFF the power supply before changing the
setting of any switch.
● Mounting and Dismounting
• Although there are no particular mounting restrictions, the
Timer should be mounted as horizontally as possible.
• When mounting the Timer on a mounting Track, loosen the
two hooks, press the Timer onto the Track, and then insert the
hooks.

A2
• The input circuit and the power supply circuit are configured
independently. The input circuit can be turned ON and OFF
without considering the ON/OFF state of the power supply.
A voltage equivalent to the power supply voltage is also
applied to the input circuit.
• 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 shortcircuited to one another. Always use the same power supply
phases.

• The power supply can be connected to the power input terminals without considering polarity.
• A DC power supply can be connected if its ripple factor is 20%
or less and the average voltage is within the allowable voltage
fluctuation range of the Timer.
• For the power supply of the input device, use an isolating
transformer in which the primary and secondary windings are
mutually isolated and the secondary winding is not grounded.

• When using the Timer in an area with excessive electronic
noise, separate the Timer and input device as far as possible
from the noise sources. It is also recommended to shield the
input signal wiring to prevent electronic interference.
• The external impulse voltage entering across the power supply
terminals has been checked against a ±1.2×50 µs standard
waveform according to JEC-210, Impulse Voltage/Current
Test, of The Institute of Electrical Engineers of Japan. Surge
or noise superimposed on the power supply may damage
internal components or cause them to malfunction. We recommend that you check the circuit waveform and use surge
absorbers. The effects on components depend on the type of
surge and noise that are generated. Always perform testing
with the actual equipment.
H3DK
● Wiring
The H3DK-H acts like a high-impedance circuit. Therefore, the
Timer may not reset if it is influenced by inductive voltage. To
eliminate inductive voltage, the wires connected to the Timer
must be as short as possible and should not be installed parallel
to power lines. If the Timer 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.

EN/IEC Standard Compliance
• Refer to the datasheet for the H3DK for cable selection and
other conditions for compliance with EMC standards.
• The power supply terminals and input terminals are not isolated. There is basic insulation between the power supply terminals and output terminals.
• If double or reinforced insulation is required, use the double or
reinforced insulation defined in IEC 60664 that is suitable for
the maximum applied voltage for the clearance, solid insulation, and other factors.
•
metal parts of the Timer. (Otherwise, the internal circuits of the
Timer may be damaged.)
The H3DK-H uses a latching relay for the output. Shock, such
as dropping the H3DK-H during shipment or handling, can
cause the output contacts to reverse to the neutral position.
Check the output status with a tester before using the H3DKH.
The life expectancy of the control output contacts is greatly
affected by switching conditions. Always confirm operation
using the actual conditions and equipment before using the
Timer and make sure that the number of switching operations
presents no problems in performance. If Timer application is
continued after performance has deteriorated, insulation failure between circuits, burning of the control output relay, or
other problem will eventually occur.
If the power supply voltage is gradually increased, a power
reset may occur or the Timer may time out. Use a switch,
relay, or other device with contacts to apply the power supply
voltage all at once.
Make sure that residual voltage or inductive voltage is not
applied after the power turns OFF.
Error in the operation time of the Timer is given as a percentage of the full-scale time. The absolute value of the error will
not change even if the set time is changed. Therefore, always
use the Timer with the set time set as close as possible to the
full-scale value of the set time range.
When switching a microload, check the specified minimum
load given for the Timer model you are using.
When setting the operating time, do not turn the dial beyond
the scale range.
If better accuracy is required in the set time, adjust the dial
while measuring the operation time.
If the Timer is reset immediately after timing out, make sure
that the circuit configuration allows sufficient resetting time.
Errors will occur in the sequence if there is not sufficient resetting time.
When directly switching a DC load, the switching capacity will
be lower than when switching an AC load.

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.

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

test conditions, and the user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations

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
