Multi-range, Multi-mode Timer
H3DK-M/H3DK-S
• Multiple time ranges and operating modes let you cover a wide
range of applications.
• The time-limit DPDT output contacts can be changed to time-limit
SPDT and instantaneous SPDT output contacts using a switch.
• Sequence checks are easily performed by setting an instanta-
neous output to 0.
• Start signal control for the H3DK-M.

When using a 24-VDC power supply voltage, there will
be an inrush current of approximately 0.25 A. Allow for
this inrush current when turning ON and OFF the
power supply to the Timer with device with a solid-
state output, such as a sensor.
DC ripple: 20% max.
The power consumption is for mode A after the Timer
times out.
For the H3DK-M@, the maximum power consumption
is given, including the current consumed by the input
circuit.
Refer to
DC Power Consumptions (Reference Infor-
mation)
on page 27 for DC power consumptions.
The control output ratings are for one H3DK operating
alone. If you operate two or more Timers side by side,
refer to
Installation Pitch and Output Switching Capac-
ity (Reference Values)
on the next page.
125 VDC: 0.15 A max. with resistive load, 125 VDC:
0.1 A with L/R of 7 ms.

The relation between the installation pitch
and the load current is shown in the follow-

If Timer is used under load conditions that
exceed the specified values, the tempera-
ture inside the Timer will increase, reducing
the life expectancy of internal parts.

There is no start input.
The output is turned ON/OFF according to the operating mode when the value
that is set on the dial is reached. *
* If the INST/TIME switch on the front of the Timer is set to INST on the H3DK-M2/-S2, relay R2 will
operate as instantaneous contacts and will turn ON/OFF in synchronization with the power supply.
