I/O Circuit and Wiring diagrams

ST4-C11

In case of PNP output
・Set the output polarity selection switch to the PNP side.

In case of PNP output

Notes:

1) The left diagram is when using manual reset. If automatic reset is used, disconnect the lead from X2 and connect it to X3. In this case, a reset (RESET) button is not needed.
2) Use a momentary-type switch as the reset (RESET) button.
3) Emission halt input is for stopping emission when open, and emitting when short-circuited. If not using the test button, short-circuit T1 and T2.
KA, KB: Force-guided relay or magnetic contactor

In case of NPN output
・Set the output polarity selection switch to the NPN side.

In case of PNP output
・Set the output polarity selection switch to the PNP side.

In case of PNP output
When using the normally open (NO) contact switch as a muting sensor, wire as shown in the figure below.
