Open collector of a
PNP transistor
or Open collector of an
NPN transistor
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 < 1
μ
A
or Open collector of
an NPN transistor
Terminals 2 and 4 are
internally connected.
Note:
Use Relays and Switches that have high contact relia-
bility because the current flowing from terminals 1 or
3 is as small as approx. 10
μ
A. It is recommended
that OMRON's G3TA-IA/ID be used as the SSR.
2. Solid-state Input
(Open Collector Input of an NPN Transistor)
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 termi-
nals 1 or 3 is as small as approx. 10
μ
A, thus allow-
ing easy connection.
2.
Select input transistors according to the following:
Dielectric strength of the collector
≥
50 V
Leakage current < 1
μ
A
