internal circuitry. The following diagram shows the terminal arrangement and
wiring for the SRT
@
-OD08S.
The following table shows the terminal arrangement and wiring for the
Remote Terminal’s output connector.
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 (includ-
ing 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 con-
nect a diode externally.
