Abstract
A relay controller for connecting a power source includes at least one relay having at least two contacts. The relay controller includes a processing device operable to selectively switch the relay contacts, and a feedback circuit adapted to identify an actual state of the relay contacts. The processing device is configured to recognize a fault contact condition of a disparity between an expected state of the relay contacts and the actual state of the relay contacts. The processing device is also configured to responsively communicate information relating to the relay fault condition.
