Opto 22 celebrates 50 years!
I have a hard time believing it's been 50 years since my dad and mom started Opto 22. My dad, Bob Engman, was an engineer who helped develop a better way to manufacture solid state relays. ... As we celebrate our 50th anniversary, I want to thank all of you, our customers, integrators, and distributors, for everything you do: using our products, telling us what works—and what doesn't—and sharing your ideas for features you need. With your help we've taken this 50-year journey from highly reliable SSRs to state-of-the-art Edge Programmable Industrial Controllers. -Mark Engman
