Terminal Arrangement
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
because it offers multiple operating modes and is different from the delayed
contact for conventional timers.

Input Connections
The inputs of the H3DE-M1/-M2 are voltage (voltage imposition or open) inputs.

1. Transistor ON
Residual voltage: 1 V max.
(Voltage between terminals B
1
and A
2
must be more than
the rated "H-level" voltage (20.4 VDC min.).)
2. Transistor OFF
Leakage current: 0.01 mA max.
(Voltage between terminals B
1
and A
2
must be less than
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
OFF, voltage between terminals B
1
and A
2
must be within
the following ranges:
When contacts are ON: 20.4 to 253 VAC/DC
When contacts are OFF: 0 to 2.4 VAC/DC
