The following table shows the terminal arrangement and wiring for the
Remote Terminal’s output connector.

Function
number
1 VCC (V) (External device power supply, + terminal)
2 GND (G) (External device power supply, – terminal)
3 OUT (Output)
4
Note 1. Terminals 3 and 4 are connected internally, so external devices should be
connected to terminal 1 (+24 V) and either terminal 3 or 4.
2. The BS– and BS+ terminals of the communications power supply (including
the I/O power supply) cannot be supplied from a flat cable, so they must
be supplied separately.
3. When inductive loads such as solenoids and valves are used, either use
loads with built-in diodes that absorb the back-electromotive force or connect
a diode externally.
