Research Summary

A PhotoMOS optically isolated relay is a solid-state relay that uses a photovoltaic MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) to achieve electrical isolation between the input and output circuits. Unlike traditional electromechanical relays, PhotoMOS relays use light signals to control the switching of the MOSFET, eliminating the need for physical contacts. The input side of the relay is optically coupled to the output side through a transparent insulation layer. When an LED on the input side is energized by an external control signal, it emits light that activates the photovoltaic MOSFET on the output side, allowing current to flow through the relay. PhotoMOS relays offer advantages such as fast switching speed, long operational life, and high resistance to shock and vibration. They find applications in areas where electrical isolation is critical, such as in medical equipment, telecommunications, and industrial control systems, providing a reliable and durable solution for signal switching and control.
