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 that the
PWR terminal is designed for safety purposes to work always in source logic mode, regardless of the setting of SW1.

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).
