Hardware Description
Chapter 4
4Ć2
The module draws power for its internal circuitry and communicates with the
programmable controller through the 1771 universal I/O chassis. You make all
other connections through the wiring arm terminals. Cable length can be up to
200 feet for these connections, depending on the gauge used. See Chapter 5 for
wiring guidelines. Figure 4.2 shows the wiring arm terminals for both control
loops.

The input and output terminals of each of the module’s control loops are in four
groups. Each group is electrically isolated from the 1771 backplane and from
the three other groups:
transducer interface terminals
discrete input terminals
