General Description

The PVT312 Photovoltaic Relay is a single-pole, normally open solid-state relay that can replace electromechanical relays in many applications. It utilizes International Rectifier’s proprietary HEXFET power MOSFET as the output switch, driven by an integrated circuit photovoltaic generator of nove construction. The output switch is controlled by radiation from a GaAlAs light emitting diode (LED) which is optically isolated from the photovoltaic generator.
