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

To wire inputs and outputs

WARNING Do not apply line voltage (mains voltage) to the controller's ports and terminals.
The Gnd terminal is shared by the inputs/outputs to the top and bottom of it.
