Solid State Relays
About Opto 22 Solid State Relays
In 1974, Opto22 introduced the first liquid epoxy-filled line of power solid-state relays (SSR). This innovation in SSR design greatly improved the reliability and reduced the cost of manufacturing. At that time, they also incorporated 100% testing under full-load conditions of every relay they manufactured.
Opto 22 offers a complete line of SSRs, from the rugged 120/240/380-volt AC Series to the small footprint MP Series, designed for mounting on printed circuit boards. All Opto22 SSRs feature 4,000 volts of optical isolation. All are UL recognized, and most are CSA certified. The innovative use of room-temperature liquid epoxy encapsulation, coupled with Opto22’s unique heat-spreader technology, are key to mass producing the world’s most reliable solid-state relays.
