or Open collector of an
NPN transistor
Note: 1.
Terminals 2 and 4 (input circuit and reset circuit) are
functionally isolated.
2.
Select input transistors according to the following:
Dielectric strength of the collector
≥
50 V
Leakage current < 100
µ
A
or Open collector of
an NPN transistor
Note:
Select input transistors according to the following:
Dielectric strength of the collector
≥
50 V
Leakage current < 1
µ
A
Terminals 2 and 4 are
internally connected.
Note:
Use Relays and Switches that have high contact
reliability because the current flowing from terminals
1 or 3 is small. It is recommended that OMRON's
G3TA-IA/ID be used as the SSR.
2. Solid-state Input

Open collector of an
NPN transistor
Open collector of an
NPN transistor
Terminals 2 and 4 are
internally connected.
Note: 1.
Residual voltage in the output section of Proximity
Sensors or Photoelectric Sensors becomes less than
0.5 V because the current flowing from terminals 1 or 3
is small thus allowing easy connection.
