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. 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.)
