Who We Are

Opto 22's hardware products are widely recognized and highly regarded in the automation industry for their innovation, quality, and reliability. All products are manufactured at our 160,000-square-foot factory, adjacent to corporate headquarters in Temecula, California.

We ship more than half a million products per month, and each is individually tested before we send it to you. That's why we're confident in guaranteeing all optically isolated solid state relays and most I/O modules for life.
