Remote Terminals
Section 5-1
Note
The BS+ and BS
−
terminals of the communications power supply (including
the I/O power supply) cannot be supplied from the communications cable, so
they must be supplied separately.
The following diagram shows the terminal arrangement and wiring for the 16-
output Relay-mounted Remote Terminals (SRT
@
-ROC16 and SRT
@
-ROF16).
Note
1.
There are two each of the COM2 and COM3 terminals, and two each of
the COM4 and COM5 terminals. When power is supplied to all the termi-
nals at once, wiring the COM terminals can be simplified by short-circuiting
the central COM terminals.
2.
The maximum carry current for each terminal from COM0 to COM7 is 3 A.
When power is supplied to all the terminals at once, the total carry current
for the COM terminals connected together must not exceed 3 A.
3.
The BS+ and BS
−
terminals of the communications power supply (includ-
ing the I/O power supply) cannot be supplied from the communications ca-
ble, so they must be supplied separately.
