Terminal Wiring Guidelines, Functions, Ratings, and Requirements
Input and Output Wiring Guidelines
Table 5 and Table 6 provide information and guidelines about the functions, ratings, and requirements for the
controller input and output terminal guidelines for determining proper wire sizes and cable lengths.
In addition to the wiring guidelines in Table 5 and Table 6, use 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, must consist of stranded, insulated, and
twisted copper wires.
• Shielded cable is not required for input or output cables.
• It is best practice to use shielded cable 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.
