I/O Circuit and Wiring diagrams

PNP output type

PNP output type I/O circuit diagram
  • S1,S2
Switch S1
Test input / Large multi-purpose indicator input
ON : Vs –2.5 V to Vs
OFF : Open
Switch S2
Frequency setting input
Frequency 1 setting: Open
Frequency 2 setting: +V

Notes:

1) If the large multi-purpose indicator input wiring (Orange) is connected to +V, the orange LED lights on. When they are disconnected, the orange LED lights off.
2) Vs is the applying supply voltage.

NPN output type

NPN output type I/O circuit diagram
  • S1,S2
Switch S1
Test input / Large multi-purpose indicator input
ON : 0 to +2.5 V
OFF : Open
Switch S2
Frequency setting input
Frequency 1 setting: Open
Frequency 2 setting: +V

Note:

If the large multi-purpose indicator input wiring (Orange) is connected to 0V, the orange LED lights on. When they are disconnected, the orange LED lights off.

Connection example

Basic wiring: Min. operation only

This is the general configuration using one set of the emitter and receiver facing each other. The control output (OSSD) turns OFF if the light is interrupted, while it automatically turns ON if receive the light.

Control unit SF-C13 wiring diagram (Control category 2)

PNP output type: Min. operation only

Connect the safety light curtain control output OSSD to S1 and make a short-circuit between S2 and S3.

Control unit SF-C13 wiring diagram (Control category 2) PNP output type: Min. operation only

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.

NPN output type: Min. operation only

Connect the safety light curtain control output OSSD to S4 and make a short-circuit between S2 and S3.
