See Input and Output wiring guidelines tables for information about the functions, ratings, and requirements for the input and output terminals, and for wire sizes and cable lengths guidelines.

In addition, observe the following guidelines when wiring 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 twisted, insulated, and stranded copper wires.
  • Shielded cable is not required for input or output cables but is recommended for input and output cables that are exposed to high electromagnetic or radio frequency noise.
  • Cable runs of less than 30 m (100 ft) typically do not require an offset in the input/output software setup.
  • Cable runs over 30 m (100 ft) may require an offset in the input/output software setup.
