Abstract
Methods and apparatus provide for at least one relay with contacts transitioning from: an OFF state to an ON state in response to an ON-pulse of current through a coil in a first direction; and the ON state to the OFF state in response to an OFF-pulse of current through the coil in a second, opposite direction. A driver circuit operates to produce the ON-pulse through the coil of the relay in response to a control signal commanding the ON-state of the contacts; produce the OFF-pulse of current through the coil of the relay in response to a control signal commanding the OFF-state of the contacts; and produce the OFF-pulse of current through the coil of the relay in response to a loss of operating potential across the pair of operating power nodes.
