4) Sink logic type
In this logic, a signal switches on when a current flows out of the corresponding signal input terminal.
Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output
signals.

When using an external power supply for transistor output, use terminal PC as a common to prevent
misoperation caused by undesirable current. (Do not connect terminal SD of the inverter with terminal
0V of the external power supply. When using terminals PC-SD as a 24VDC power supply, do not install
the power supply in parallel outside the inverter. Doing so may cause misoperation due to leakage
current.)
