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.

*1. 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.
*2. DC ripple: 20% max.
*3. The power consumption is for mode A after the
Timer times out.
For the H3DK-M@, the maximum power consump-
tion is given, including the current consumed by the
input circuit.
*4. Refer to DC Power Consumptions (Reference In-
formation) on page 27 for DC power consumptions.
*5. The control output ratings are for one H3DK oper-

Note 2. When power is supplied in flicker ON start mode, the OFF indicator lights momentarily. This, however, has no effect on the performance of the Timer.

*1. 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.
*2. DC ripple: 20% max.
*3. Refer to DC Power Consumptions (Reference Information) on page 27 for DC power consumptions.
*4. 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 Capacity
(Reference Values) on the next page.
*5. For the H3DK-GE, approx. 6 A of inrush current will flow when the power supply is turned ON. When selecting the device connected to the Timer, allow leeway in
the current ratings.
