Claim:
1. A relay comprising: a first terminal; a second terminal; a third terminal; a fourth terminal; separable contacts electrically connected between said first and second terminals; an actuator coil comprising a first winding and a second winding, the first winding electrically connected between said third and fourth terminals, the second winding electrically connected between said third and fourth terminals; a processor; an output; a first voltage sensing circuit cooperating with said processor to determine a first voltage between said first and second terminals; and a second voltage sensing circuit cooperating with said processor to determine a second voltage between said third and fourth terminals, wherein said processor is structured and provided with logic that configures said processor to determine that said separable contacts are closed when the first voltage does not exceed a first predetermined value and the second voltage exceeds a second predetermined value and to responsively output a corresponding status to said output.
