Safety Precautions
Refer to Safety Precautions for All Timers.
Format of Warning Indications
Meaning of Graphic Symbols for Ensuring Product Safety
Switching arcs or relay heating may cause fire or
explosion. Do not use the Timer in the presence of
inflammable or explosive gases.
The H3DT 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.
• 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.
• Use the Timer within the ambient operating temperature and
ambient operating humidity ranges given for the Timer model you
are using.
• Do not use or store a Timer in the following locations.
• Locations subject to water, oil, or chemicals
• Outdoor locations or under direct sunlight
• Locations subject to dust or corrosive gases (sulfurizing gases,
ammonia, chloride gas, silicon gas, etc.)
• Locations subject to vibration and large shocks
• Locations subject to wind and rain
• Locations subject to insects or small animals
• Each switch has a snap mechanism that secures the switch at
given positions. Set each switch to one of these positions. Do not
set a switch midway between two positions. Malfunction or failure
could result from an improper setting.
• 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.
• The terminal block may be damaged if you insert a screwdriver in
the release hole with excessive force.
• Do not wire anything to the release holes.
• Do not tilt or twist a flat-blade screwdriver while it is inserted into a
release hole on the terminal block. The terminal block may be
damaged.
• Insert a flat-blade screwdriver into the release holes at an angle.
The terminal block may be damaged if you insert the screwdriver
straight in.
• Do not allow the flat-blade screwdriver to fall out while it is inserted
into a release hole.
• Do not bend a wire past its natural bending radius or pull on it with
excessive force. Doing so may cause the wire disconnection.
• Do not insert more than one wire into each terminal insertion hole.
• To prevent wiring materials from smoking or ignition, use the wiring
materials given in the following table.
Note: Please use Ferrules with UL certification (R/C).
• Use only the specified wires for wiring.
• When wiring the terminals, allow some leeway in the wire length.
• 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.
• 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.
Be sure you understand the contents of this document and handle the
Timers according to the instructions provided.
Changing Switch Settings
Do not change the time unit, operating mode, or INIT/ TIME switch
while the power is being supplied to the Timer. 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.
• To mount the Timer to a DIN Track, hook the Timer onto the DIN
Track and press the Timer in the direction of the arrow until you
hear it lock into place.
• To remove the Timer, insert a screwdriver into the hook on the top
or bottom and pull out the hook to release the Timer.
• It will be easier to mount and dismount the Timer if a distance of 30
mm or more is provided between the bottom of the Timer and other
equipment.
Screw Mounting
1. Pull out the two hooks on the back of the Timer to the outside until
you hear them click in place.
2. Insert M3 screws into the hook holes and secure the Timer.
Power Supply
• 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.
(H3DT-N and H3DT-L only)
• The H3DT-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.
Relationship between Input and Power Supply
Circuits (H3DT-N/L)
• 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 short-circuited to
one another. Always use the same power supply phases.
•
The power supply circuits for H3DT-series Timers use switching
mode. Therefore, if there is a transformer or other device with a large
inductance component on the power supply line, the inductance will
cause a reverse voltage. If that occurs, insert a CR filter in the power
supply line to reduce the reverse voltage.
Environment
• 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.
• The Timer may be be affected by incoming radio wave
interference. Do not use the Timer near radio wave receivers.
• Do not use the Timer in circuits with waveform distortion. Error will
be large due to waveform distortion.
• Do not install the Timer immediately next to heat sources.
Wiring
1. Connecting Wires to the Push-In Plus Terminal Block
Part Names of the Terminal Block
Connecting Wires with Ferrules and Solid Wires
Insert the solid wire or ferrule straight into the terminal block until the
end touches the terminal block.
If a wire is difficult to connect because it is too thin, use a flat-blade
screwdriver in the same way as when connecting stranded wire.
Connecting Stranded Wires
Use the following procedure to connect the wires to the terminal block.
1. Hold a flat-blade screwdriver at an angle and insert it into the
release hole. The angle should be between 10° and 15°.
If the flat-blade screwdriver is inserted correctly, you will feel the
spring in the release hole respond.
2.
With the
flat-blade
screwdriver still inserted into the release hole,
insert the wire into the terminal hole until it strikes the terminal block.
3. Remove the flat-blade screwdriver from the release hole.
Checking Connections
• After the insertion, pull gently on the wire to make sure that it will
not come off and the wire is securely fastened to the terminal block.
• To prevent short circuits, insert the stripped part of a stranded or
solid wire or the conductor part of a ferrule until it is hidden inside
the terminal insertion hole. (See the following diagram.)

Removing Wires from the Push-In Plus Terminal Block
Use the following procedure to remove wires from the terminal block.
The same method is used to remove stranded wires, solid wires, and
ferrules.
1. Hold a flat-blade screwdriver at an angle and insert it into the
release hole.
2. With the flat-blade screwdriver still inserted into the release hole,
remove the wire from the terminal insertion hole.
3. Remove the flat-blade screwdriver from the release hole.
3. Recommended Ferrules and Tools
Recommended ferrules
Note: 1. Make sure that the outer diameter of the wire coating is
smaller than the inner diameter of the insulation sleeve of
the recommended ferrule.
2. Make sure that the ferrule processing dimensions conform
to the following figures.
Recommended Flat-blade Screwdriver
Use a flat-blade screwdriver to connect and remove wires.
Use the flat-blade screwdriver from below the list.
The following table shows manufacturers and models as of 2015/Dec.
If you wire crossovers and connect terminal blocks in parallel, a large
current will flow. Make sure that the current does not exceed 10 A.
• Do not connect anything to unused terminals.
• Wire all terminals correctly.
• Check all wiring before you turn ON the power supply to the Timer.
• The H3DT-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.
Operating Frequency
• The H3DT-H may malfunction if it is used as shown below. Do not
use the H3DT-H in these ways.
Timer Repeatedly Times Out in Cycles of 3 s or Less
In the above case, use the H3DT-N/L in D mode (signal OFF
delay).
•
If you use Flicker Mode and set the dial on the H3DT-F to the minimum
setting, the contacts may be damaged. Avoid this type of application.
Options
• Use the Y92A-D1A for the Front Cover.

Other Precautions
• If the Timer is mounted on a control panel, dismount the Timer from
the control panel before carrying out a voltage withstand test
between the electric circuits and non-current-carrying 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 H3DK-H.
• 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.
• 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.
• Do not install the Timer in any way that would place a load on it.
• When cleaning the Timer, do not use thinners or solvents. Use
commercial alcohol.
• If better accuracy is required in the set time, adjust the dial while
measuring the operation time.
• Do not construct a circuit for the H3DT-H that would allow
overcurrent and burning to occur if the NO, NC and SPDT contacts
are short-circuited. Arcing may generate short-circuiting between
contacts if there is short-circuiting because of conversion to the
MBB contacts caused by asynchronous operation of the NO and
NC contacts, the interval between the NO and NC contacts is
small, or a large current is left open.
• 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.
• Refer to the datasheet for the H3DK for cable selection and other
conditions for compliance with EMC standards.
Precaution on EN Standard Compliance
The H3DT complies with EN 61812-1 when it is built into a panel, but
observe the following handling methods to ensure compliance with
the requirements of this standard.
Wiring
Overvoltage category III
Pollution degree 2
• Open-frame Device
• If basic, double, or reinforced insulation is required, use the basic,
double, or reinforced insulation defined in IEC 60664 that is
suitable for the maximum applied voltage for the clearance, solid
insulation, and other factors.
• The power supply terminals and input terminals are not isolated
from each other.
• There is basic insulation between the power supply terminals and
output terminals.
• There is basic insulation between the input terminals and output
terminals.
• The operating section must have reinforced or double insulation.
• The sides of the case are not isolated.
• Connect the output contacts (contacts with different polarity) so
that they reach the same potential.
Recommended Replacement Periods and Periodic Replacement
as Preventive Maintenance
The recommended replacement period for preventive maintenance is
greatly influenced by the application environment of the product. As a
guideline for models that do not have a Maintenance Forecast
Monitor, the recommended replacement period is 7 to 10 years.* To
prevent failures that can be caused by using a product beyond its
service live, we recommend that you replace the product as early as
possible within the recommended replacement period. However,
realize that the recommended replacement period is for reference
only and does not guarantee the life of the product.
Many electronic components are used in the product and the product
depends on the correct operation of these components to achieve
product functions and performance. However, the influence of the
ambient temperature on aluminum electrolytic capacitors is large, and
the service life is reduced by half for each 10°C rise in temperature
(Arrhenius law). When the capacity reduction life of the electrolytic
capacitor is reached, the product may fail. We therefore recommend
that you replace the product periodically to minimize product failures
in advance.
*The following conditions apply: rated input voltage, load rate of 50%
max., ambient temperature of 35°C max., and the standalone
mounting method.
This product model is designed with a service life of 10 years
minimum under the above conditions.

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 Prod-
uct 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 equip-
ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop-
erty. Please know and observe all prohibitions of use applicable to this Prod-
uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
3. Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitabil-
ity 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 require-
ments. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial 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.
5. Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
