Remote Terminals
Section 5-1
Internal Circuits
The following diagram shows the internal circuits for all of the Relay/Power
MOS FET Relay-mounted Remote Terminals (SRT
@
-ROC08/ROC16 and
SRT
@
-ROF08/ROF16).
Terminal Arrangement
and Wiring
Install the following M3 crimp terminals on the signal wires and connect to the
terminal block.
Note
Tighten the terminal block screws to the specified tightening torque of
0.5 N
⋅
m.
The following diagram shows the terminal arrangement and wiring for the 8-
output Relay-mounted Remote Terminals (SRT
