Safety Precautions
●Refer to Safety Precautions for All Timers.
Note: The following is common for all H3DK models.
Switching arcs or relay heating may cause fire or
explosion. Do no t 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 fre-
quency and number of o peration s. Chec k b oth 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 ther-
mal switch in the loa d ci rc ui t.
Do not remove the external case.
Minor electric shock, fire, or equipment failure
may sometimes occur. Do not disassemble, mod-
ify, or repair the Timer or touch any in ternal parts.
• 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 malfunc-
tion or damage to components. Check the application environ-
ment.
• Store the Timer within the rated ranges given for the Timer
model you are using. If the Timer is stored below −20°C, allo w
it to warm up for three hours at room temperature before turn-
ing 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 expo-
sure given fo r t he Tim e r m o de l yo u ar e us ing.
• 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 elec-
tricity, 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 compo-
nents 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 t he ti med o ut cond itio n f or a lon g peri od of
time at high temperatures, internal components (such as elec-
trolytic capacitors) may deteriorate quickly.
• The exterior of the Timer ma y be damage d by organic solvents
(such as thinners or benzene), strong alkali, or strong acids.
• For Timers with AC power input, use a commercial power sup-
ply for the power supply voltage. Although some inverters give
50/60 Hz as the output frequency, do not use an inverter out-
put 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 sub-
ject 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. Depend ing on th e operati ng environme nt, th e indica-
tors and plastic parts may deteriorate faster than expected,
causing the indicators to fail. Periodically perform inspections
and replacements.
Caution Precautions for Safe Use
H3DK
26
●Changing Switch Settings
Do not change the time uni t, time sca le, opera ting mode, or INI T/
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 Dismoun tin g
• Although there are no particular mounting restrictions, the
Timer should be mounted as horizontally as possibl e.
• When mounting the Timer on a mounting Track, loosen the
two hooks, press the Timer onto the Track, and then insert the
hooks.
• When removing the Timer, pull out the two hooks, and then
remove the Timer from the Track
• It will be easier to mount and dismount the Timer if a distance
of 30 mm or more is provided between the bott om of the Timer
and other equipment.
●Power Supply
• The power supply can be connected to the power input termi-
nals 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 isolat ed and the secondary winding is not grounded.
(H3DK-M1 and H3DK-M2 only)
• The H3DK-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 Cir-
cuits (H3DK-M1/-M2)
• 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 dif f erent in p hase o r the t ermin als wi ll be short-
circuited to one another. Always use the same power supply
phases.
●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 volt age 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 t hem to malfu nction . We recom-
mend 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.

●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 Ti mer is inf luence d by i ndu ctiv e volt age tha t
is 30% or more of the rated voltage, connect a CR filter with a
capacitance of approximately 0.1 µF and a resistance of approx-
imately 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 H3DK-H may malfunction if it is used as shown below. Do
not use the H3DK-H in these ways.
Timer Repeatedly Ti mes Out in Cycles of 3 s or Less
In the above case, use the H3DK-M2/-M1 in D mode (signal
OFF delay).
●DC Power Consumptions (Reference Information)
●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 o f the T imer. (Ot herwise , the i nt ernal ci rcui ts o f 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 fail-
ure between circuits, burning of the control output relay, or
other problem will eventual ly 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 afte r the p ower turns OFF.
• Error in the operation time of the Timer is given as a percent-
age 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 Tim er with the set time set as c lose as poss ible to th e
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 reset-
ting 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.
• The power supply terminals and input terminals are not iso-
lated. There is basic insulation between the power supply ter-
minals 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 insula-
tion, and other factors.

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
for clerical, typographical or proofreading errors or omissions.
