In addition to the wiring guidelines in the following
table, observe these guidelines when wiring
controller inputs and outputs:
• Run all low-voltage wiring and cables separate
from high-voltage wiring.
• All input and output cables, regardless of wire
size or number of wires, should consist of
stranded, insulated, and twisted copper wires.
• Shielded cable is not required for input or output
cables.
• Shielded cable is required for input and output
cables that are exposed to high electromagnetic
or radio frequency noise.
• Inputs or outputs with cables less than 30 m
(100 ft) typically do not require an offset in the
software setup. Cable runs over 30 m (100 ft) may
require an offset in the input/output software
setup.
