What are the cable specifications for wiring controller inputs to field devices.

Issue

What are the cable specifications for wiring controller inputs to field devices.

Environment

  • Inputs
  • Cable
  • Sensors
  • End devices

Cause

There is no specification for IO field wiring.


 

Resolution

The line drop produced by cable resistance should be taken into account when choosing the wire gage for Input devices.

It is good practice to run a shielded cable for analog inputs simply because it give you a way to drain off any externally induced voltage.
