Manufacturer Code: OPTO22

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, 40 years later, we're still privately held, lean, and run by engineers. Our flat organization fosters individual responsibility, quick response to customers' needs, and fast development of cutting-edge products. Open Standards Opto 22 products are designed to run on non-proprietary communication standards like Ethernet and the Internet Protocol (IP). Open standards and commercially available technologies decrease the cost of automation and open up data for use where it's needed. Over the years we've had a hand in promoting industry standards. Red-white-yellow-black modules - standard developed by Opto 22 In 1978 we developed the red-black-yellow-white I/O module color-coding scheme, still the standard today. In 1982 we introduced Optomux, which soon became an industry standard protocol. In 1995 we started the OPC task force (later the OPC Foundation) with four other founding members, to develop standards for interoperability among vendors' products. In 1998 we introduced the first commercial Ethernet-based I/O unit. Emphasis on Quality Opto 22 employee inspects products for 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. Made and Supported in the U.S.A. Since all our products are manufactured and individually tested at our headquarters in Temecula, California, we control quality from the ground up. So we also give you FREE pre-sales engineering help, free hands-on training, and free product support from experienced engineers.
