Output wiring
To size output wiring, consider the following:
•
Total loop distance from the controller to the controlled device
NOTE
Include the total distance of actual wire. For 2-conductor wires, this is twice the cable length.
•
Acceptable voltage drop in the wire from the controller to the controlled device
•
Resistance (Ohms) of the chosen wire gauge
•
Maximum current (Amps) the controlled device requires to operate
