h3de-s Omron Corporation, h3de-s Datasheet - Page 6

• Manufacturer Part Number: h3de-s
• Description: Solid-state Timer
• Manufacturer: Omron Corporation

■ 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.
■ 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
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
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
