Abstract
One example includes a relay device that is comprised of a galvanic isolation barrier, a protection control and power extractor, and an electronic switch. The galvanic isolation barrier is coupled to an input of the relay device and receives a switch control signal and outputs another switch control signal. The protection control and power extractor is coupled to an output of the galvanic isolation barrier. The protection control and power extractor extracts power from a power supply coupled to the relay device. The protection control and power extractor is responsive to the other switch control signal and generates a protection signal in response to a determination of an operating parameter of the relay device. The protection control and power extractor further outputs an electronic switch device signal based on the generated protection signal.
