Solid-State Relays Features Rugged, epoxy encapsulation construction 4,000 volts of optical isolation Subjected to full load test and six times the rated current surge before and after encapsulation Unique heat-spreader technology Guaranteed for life Opto 22 Power Series SSR improvements and the same 100% testing policy established over 40 years ago, Opto 22 is still recognized today for the very high quality and reliability of all our solid-state relays. Solid-State Relays Overview In 1974, Opto 22 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, we also incorporated into our manufacturing process 100% testing under full load conditions of every relay we produced. By 1978, Opto 22 had gained such a reputation for reliability that we were recognized as the world’s leading manufacturer of solid-state relays. Through continuous manufa...
