Input and output wiring guidelines
Table 2 provides information and guidelines about
the functions, ratings, and requirements for the
expansion module input and output terminals, and
references guidelines for determining proper wire
sizes and cable lengths.
In addition to the wiring guidelines in Table 2,
observe the following guidelines when wiring
expansion module 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 recommended for input
and output cables that are exposed to high
electromagnetic or radio frequency noise.
• Inputs/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.
