Input Signal (NPN)
■
When using an external power supply
Input signals are treated as active when the photocoupler is ON.
When using an external power supply, the input signals become active when the input pin and the
external power supply ground are ON.
■
When using an internal power supply (optional)
Input signals are treated as active when the photocoupler is ON.
When using an internal power supply, the input signals become active if the input pin and the
COM- pin are shorted.
If connecting a two-wire external device, such as a sensor, use one which has a leakage current
of no more than 0.3 mA. If you use a device with a leakage current of more than 0.3 mA, it may
not turn OFF.
Caution
Do not assign wiring other than the wiring specified above.
Assigning the wrong wiring can damage the internal circuits.
