Terminal Wiring Guidelines, Functions, Ratings, and Requirements
Input and Output Wiring Guidelines
Table 3
provides information and guidelines about the functions, ratings, and requirements for the controller input
and output terminals; and references guidelines for determining proper wire sizes and cable lengths.
In addition to the wiring guidelines in
Table 3
, 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 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.
