Key Features
- 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
- Through continuous manufa
