AC (120/240V) Output Module 7
Publication 1771ĆIN031B-EN-P - November 2002
You make 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
Turn the power to the chassis off before
connecting or disconnecting any wiring. Turn off
power to the I/O chassis before inserting the
module into the chassis.
•
Failure to remove power from the backplane
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. 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.
3. Make your connections to the field wiring arm as shown in the
connection diagram. (Use the label on the front of the wiring arm
to identify your 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 = outputs 00 through 17
Module group 2 = outputs 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 1, 11, 21 and 31 are
ac high (L1).
