Note (1) 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.
(2) Use a maximum current of 500 mA for each V1, V2, G1, and G2 terminal
aside from the I/O power supply terminals.
(3) When using an inductive load, such as a solenoid valve, either use a built-
in diode to absorb the counterelectromotive force or install an external di-
ode.
(4) Do not wire NC terminals.
