A MOSFET relay is a fully functional alternative to an electromechanical relay. Omron’s expanded range of MOSFET relays (type G3VM) set the benchmark in Solid State Relays (SSRs). These products are manufactured using the latest advances in automated production and include a variety of improved construction technologies within the areas of the input LED, PDA (Photo Diode Array used as photocoupler) and MOSFET chips used in the load switching circuit.
