Table 1 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 1, 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.
