Sink logic and source logic
●
In sink logic, a signal switches on when a current flows from the corresponding signal input
terminal. Terminal SD is common to the contact input signals. Terminal SE is common to
the open collector output signals.
●
In source logic, a signal switches on when a current flows into the corresponding signal input
terminal. Terminal PC is common to the contact input signals. Terminal SE is common to
the open collector output signals.
