Sink logic/source logic (When an external power supply is used)

The P24/PLC terminal is used to connect to an external power supply or to insulate a terminal from other input or output terminals. Use the slide switch SW1 to switch between sink logic and source logic configurations.

Note: Be sure to connect the 0V terminal on the external power supply to the CC terminal on the inverter.

*When OUT1 is used as a pulse output terminal (when SW4 is in the PULS position), the circuit shown below is always formed regardless of the logic selected (sink or source) and the power supply used (internal or external power supply). !
