4) Sink logic type and source logic type
• The sink logic type is a logic where a signal turns 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 sig-
nals.
• The source logic type is a logic where a signal turns 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 col-
lector output signals.

When using an external power supply for transistor output
• Sink logic type
Using terminal PC as a common terminal prevents a
malfunction 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 a
power supply in parallel in the outside of the inverter.
Doing so may cause a malfunction due to undesir-
able current.)
• Source logic type
Use terminal SD as a common to prevent a malfunc-
tion caused by undesirable current.
