Company Overview
Opto 22 was founded in 1974 by engineers who designed a better solid-state relay and chose to build it in a non-corporate, flat organization. Now, 45+ years later,

we're still privately held, lean, and run by engineers. Opto 22 products are designed to run on non-proprietary communication standards like Ethernet,

the Internet Protocol (IP), MQTT, and more. Emphasis on Quality:-Opto 22 I/O, controllers, and SSRs are famous for their quality and reliability.

Customers often comment about their dusty, 20-year-old "Optos" still doing the job in the back of a factory somewhere. With this

kind of reliability, we can afford to guarantee SSRs and most I/O modules for life.
