channel-to-channel isolation is required.
You make connections to the module through the 1771-WN field
wiring arm shipped with the module. The arm pivots on the chassis
to connect with the 40 terminals on the front of the module. The
wiring arm allows the module to be removed from the chassis
without disconnecting 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.
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 associated with that input.
You should identify the labels on the wiring arm with the name or
number of the device connected at each terminal.
