Wire the 1755-IF8 Analog
Input Module
This module features 8 single-ended analog inputs or 4 differential
analog inputs. Two-wire or four-wire transmitters can be used. The
devices cannot be powered from the GuardPLC module. An external
power supply is required for all analog transmitters. Single-ended
transmitters connect between the Ix
+ and I- terminals. For example:
pins 1 and 2, 3 and 4, 5 and 6. Differential transmitters connect
between Ix+ and x- terminals. For example, pins 1 and 10, 3 and 12, 5
and 14.
All reference poles (I-) are internally connected.
