Note: 1. The relay R2 can be set to either instantaneous or time-limit contact using the switch located on the bottom of the Timer.
2. DC supply voltage does not require the designation of polarity.
3. The contact symbol for the H3DE is indicated with
contact for conventional timers.
■ Input Connections
The inputs of the H3DE-M1/-M2 are voltage (voltage imposition or open) inputs.

Voltage Input Signal Levels
1. Transistor ON
Residual voltage: 1 V max.

the rated "H-level" voltage (20.4 VDC min.).)
2. Transistor OFF
Leakage current: 0.01 mA max.
(Voltage between terminals B
the rated "L-level" voltage (2.4 VDC max.).)
Use contacts that can adequately switch 0.1 mA at each
voltage to be imposed. (When the contacts are ON or
Contact
input OFF, voltage between terminals B
the following ranges:
When contacts are ON: 20.4 to 253 VAC/DC
When contacts are OFF: 0 to 2.4 VAC/DC
