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