Below is the 2 most common wiring diagrams.
With all relays operating on 48v or +/-24v max current draw is 18mA per GO between RC pcb + any LED or lamp current.
Control voltage can be changed to 5v to 52v or +/-2.5v to +/-34v by 3 resistor changes and the 2 relay changes from to 5v or 12v or 24v types.
When ordering let us know what standard power rails you have and we can setup the kit with correct parts to work for your setup perfectly.
I will add more wiring schematics for other voltages as needed.
