General Description
The PVT422 Series Photovoltaic Relay is a dualpole, normally open solid-state relay that can replace electromechanical relays in many applications. It utilizes International Rectifier’s HEXFET power MOSFET as the output switch, driven by an integrated circuit photovoltaic generator of novel construction. The output switch is controlled by radiation from a GaAlAs light emitting diode (LED) which is optically isolated from the photovoltaic generator.
