Sink logic and source logic
• In the 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 the 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.
• When using an external power supply for transistor output
Sink logic
Use terminal PC as a common terminal, and perform
wiring as shown below. (Do not connect terminal SD of the
inverter with the terminal 0 V of the external power supply.
When using terminals PC-SD as a 24 VDC power supply,
do not install an external power supply in parallel with the
inverter. Doing so may cause a malfunction in the inverter
due to undesirable currents.)
Source logic
Use terminal SD as a common terminal, and perform
wiring as shown below. (Do not connect terminal PC of the
inverter with terminal +24 V of the external power supply.
When using terminals PC-SD as a 24 VDC power supply,
do not install an external power supply in parallel with the
inverter. Doing so may cause a malfunction in the inverter
due to undesirable currents.)
