The relays are constructed as a multi chip - Ground start hybrid device. Actuation control is via an infrared LED. The - Ground fault protection output switch is a combination of a photodiode array with Instrumentation MOSFET switches and control circuity. Industrial controls AGENCY APPROVALS UL1577: file no.
