Reply to "MTH Scaletrax 45-1028 ITAD – Are the NO and NC Relay Contacts supposed to provide power or ground?"

Why not swap "HOT" and "GROUND" wires powering the ITAD? It's AC so the ITAD electronics does not know the difference.

Then, the COM output to your accessory will be "HOT" and the NO/NC outputs to your accessory will be "GROUND" thereby conforming to your "standard activation methodology".
