8 Electromechanical Relay Contact Output Module
The 1771-OW16 module is a modular component of the 1771 I/O system
requiring a properly installed system chassis. Refer to publication 1771-IN075
for detailed information on acceptable chassis, proper installation, and
grounding requirements. Limit the maximum adjacent slot power dissipation
to 10W maximum, or derate the module in accordance with the derating curve
in the specifications section of this installation instruction.
Connect Wiring to the Field
Wiring Arm Make wiring connections to the module through the field wiring arm (cat. no.
1771-WN). The arm pivots on the I/O chassis to connect with terminals on
the front of the module and acts as a terminal strip. The wiring arm allows the
module to be removed from the chassis without disconnecting the wiring.
1. Make certain all power is removed from the module before making
wiring connections.
2. Swing the wiring arm up into position on the front of the module. The
locking tab on the module will secure it into place.
Attach the wiring arm (1771-WN) to the horizontal
bar at the bottom of the I/O chassis.
The wiring arm pivots upward and connects with
the module so you can install or remove the
module without disconnecting the wiring.

WARNING
When you connect or disconnect the wiring arm with field
side power applied, an electrical arc can occur. This could
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazrdous
before proceeding.
WARNING
If you connect or disconnect wiring while field side power
is applied, an electrical arc can occur. This could cause an
