A relay includes a first terminal, a second terminal, a third terminal, a fourth terminal, separable contacts electrically connected between the first and second terminals, an actuator coil comprising a first winding and a second winding, the first winding electrically connected between the third and fourth terminals, the second winding electrically connected between the third and fourth terminals, a processor, an output, a first voltage sensing circuit cooperating with the processor to determine a first voltage between the first and second terminals, and a second voltage sensing circuit cooperating with the processor to determine a second voltage between the third and fourth terminals. The processor determines that the 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 responsively outputs a corresponding status to the output.
