DC (20-60V) Input Module Cat. No. 1771-ICD Series B

Publication 1771-5.29 – February 2000

You can change the position of these keys if system redesign and
rewiring makes insertion of a different module necessary.

Installing the Input Module

To install the dc input module in your series B or later 1771 I/O
chassis, follow the steps listed below.

!

ATTENTION: Remove power from the 1771 I/O
chassis backplane and field wiring arm before
removing or installing an I/O module.

Failure to remove power from the backplane or wir-
ing 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.

1. Turn off power to the I/O chassis.

2. Place the module in the plastic tracks on the top and bottom of the

slot that guides the module into position.

3. Do not force the module into its backplane connector. Apply firm,

even pressure on the module to seat it properly.

4. Snap the chassis latch over the top of the module to secure its

position.

5. Connect the wiring arm to the module.

6. Make wiring connections to the field wiring arm as indicated in

“Connecting Wiring to the Input Module.”

!

ATTENTION: Proper polarity must be observed
with dc power connections. Reverse polarity, or
application of ac voltage could damage the module.

Connecting Wiring to the Input Module

Connections to the input module are made to the field wiring arm
(cat. no. 1771-WH) shipped with the module. Attach the wiring arm
to the pivot bar on 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 wires.
