Precautions for Correct Use
•
The V1 and V2 terminals as well as the G1 and G2 terminals of the I/O power supply are not
connected internally. Supply power separately for V1-G1 and V2-G2.
•
When using an inductive load, such as a solenoid valve, either use a built-in diode for
absorbing the counterelectromotive force or install an external diode. (Refer to "A-4 Wiring
External Output Signal Lines" in Page A - 78.)
•
Do not wire NC terminals.
