H3DK Datasheet, PDF (22/30 Pages) Omron Electronics LLC – Solid-state Timers

H3DK-H
*1. DC ripple: 20% max. (A single-phase, full-wave rectifying power supply can be connected.)
*2. Refer to DC Power Consumptions (Reference Information) on page 27 for DC power consumptions.
*3. 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.

parts): 1.5 kV for 24-VAC/DC and 48-VAC/DC models, 4.5 kV for all other
models.
Noise immunity

1-ns rise): ±1.5 kV (between power supply terminals)
Static immunity
Malfunction: 4 kV, Destruction: 8 kV
Vibration ^{Destruction 0.75-mm single amplitude at 10 to 55 Hz for 2 h each in 3 directions}
resistance _{Malfunction 0.5-mm single amplitude at 10 to 55 Hz for 10 min each in 3 directions}
● Installation Pitch and Output
Switching Capacity (Reference
Values)
The relation between the installation pitch
and the load current is shown in the fol-
lowing graph. (Except for the H3DK-GE)
If Timer is used under load conditions that
exceed the specified values, the tempera-
ture inside the Timer will increase, reduc-
ing the life expectancy of internal parts.

The Timer operates as soon as the Timer is turned ON. The
Timer starts timing when the power is turned OFF and the output
is turned OFF when the time set on the dial elapses.
