AC (24V) Input Module 5
The 1771-IN 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.
Connect Wiring to the Field
Wiring Arm Make wiring connections to the module through the 10 terminal field wiring
arm (cat. no. 1771-WA). 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.
Place the module in the card guides on the top and bottom of the
chassis that guide the module into position.
Important: Apply firm even pressure on the module to seat it
into its backplane connector .
