DC (10–30V) Output Module 7

Publication 1771-IN036C-EN-P - July 2002

WARNING

When you connect or disconnect the wiring arm

with field power applied, an electrical arc can

occur. This could cause an explosion in hazardous

location installations. Be sure power is removed

or the area is nonhazardous before proceeding.

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

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.

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 wiring.

ATTENTION

The field wiring arm terminal identification

number is not the same as the number of the bit

which controls that output.

I/O Module Groups

Each module condenses two full module groups (32 outputs) into

each I/O chassis slot. For example:

Module group 1 = inputs 00 through 17

Module group 2 = inputs 00 through 17 (module group 2

represents the second set of outputs).

Terminals 1 through 20 represent module group 1. Terminals 21

through 40 represent module group 2. Terminals 10, 20, 30 and 40

are DC common and terminals 1, 11, 21 and 31 are DC power.
