6 Isolated 24V dc Output Module
The 1771-OQ 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 15.5W maximum.
Connect Wiring to the Field
Wiring Arm Make wiring connections to the module through the field wiring arm (cat. no.
1771-WF). 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.

1771-WF
The wiring arm pivots upward and connects with the
module so you can install or remove the module
without disconnecting the wires.
Attach the wiring arm (1771-WF) to the horizontal bar
at the bottom of the I/O chassis.
ATTENTION
Remove power from the 1771 I/O chassis backplane and
field wiring arm before removing or installing the I/O
module.
• Failure to remove power from the backplane or wiring
arm could cause module damage, degradation of
performance, or injury.
• Failure to remove power from the backplane could
cause injury or equipment damage due to possible
unexpected operation.
IMPORTANT
The field wiring arm terminal identification number is not
the same as the number of the bit which controls that
output
