Open collector of a

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

µA

or Open collector of

an NPN transistor

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 as small as approx. 10

µA. 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

terminals 1 or 3 is as small as approx. 10

µA, thus

allowing easy connection.

2. Select input transistors according to the following:

Dielectric strength of the collector

≥ 50 V

Leakage current < 1

µA
