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. Connect one terminal of your 2-wire input device to terminals 0 thru 7.
Use stranded 14 or 16 AWG (2.0-1.5mm
2
) to minimize the voltage drop
over long cable distances.
ATTENTION
Remove power from the 1771 I/O chassis backplane and
field wiring arm before removing or installing the 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.
IMPORTANT
The field wiring arm terminal identification number is not
the same as the number of the bit which controls that
output
