Field Wiring Arms
Wiring to and from user I/O devices connects to a separate Field Wiring Arm
for each I/O module. The Field Wiring Arm is a terminal strip that pivots up
and down for quick, easy insertion and removal of I/O modules (Figure 2.7)
without disturbing filed wiring. This aids in start-up and troubleshooting by
shortening the time needed to replace I/O modules, thus decreasing down-time.
Cat. No. 1771-WA Field Wiring Arms are shipped with the I/O Chassis (one for
each I/O Module slot). This Field Wiring Arm is used with most I/O modules.
if a certain module requires a different Field Wiring Arm, it is shipped with that
module. In this case, use the Field Wiring Arm that comes with the module.
