All Opto 22 products are designed, manufactured, and supported in the U.S.A. from our Temecula, California headquarters and factory
Emphasis on Quality
Opto 22 I/O, controllers, and SSRs are famous for their quality and reliability. Customers often comment about their dusty, 40-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.
Making Automation Simple
Because we're engineers, we know what it's like to lose an idea because it's too hard to implement. Designing and integrating automation systems can be frustrating. We simplify your job with open standards, easy-to-use software, clear documents, and how-to videos.
