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 leakage current. (Do not connect terminal SD of the inverter with terminal 0V of
the external power supply.)
