Abstract: A relay control circuit for use with a relay having a coil voltage input. The relay control circuit includes a first input to receive a first voltage capable of energizing the relay from a de-energized state, a second input to receive a second voltage, less than the first voltage, that is capable of maintaining the relay in an energized state, and means, responsive to a relay control signal having one of a first state and a second state, for switchably coupling the coil voltage input to the first input for a period of time sufficient to energize the relay in response to the relay control signal having the first state, and for switchably coupling the coil voltage input to the second input in response to expiration of the period of time.
