Opto 22

American Opto 22 Company is a world-leading technology product manufacturer that provides high-quality hardware and software solutions for connecting real-life devices with computer networks..Its customer applications include data acquisition, enterprise management, remote monitoring and control, industrial automation, SCADA.Opto 22 was one of the first companies to recognize and provide system solutions for connecting networks, computers and real-world devices..Currently, there are over 80 million devices connected to the Opto 22 system around the world.Opto 22's products have become a good choice for global system integrators due to their high reliability, easy connection to various existing industrial control equipment, and high overall cost performance...

Opto 22 was founded in 1974 by engineers who designed better solid state relays and chose to manufacture in a non-corporate flat organization.Our flat organization fosters individual responsibility, rapid response to customer needs, and rapid development of cutting-edge products.Now, nearly 50 years later, we are still privately owned, lean and run by engineers..

Product Range.

Relays, solid state relays, modules, PLCs, controllers, power supplies.

open standards.

Opto 22 products are designed to run non-proprietary communications standards such as Ethernet, Internet Protocol (IP), MQTT, etc...

Open standards and commercial technologies reduce automation costs and open data for use when needed..

For many years we have been driving the development of industry standards..

In 1978, we developed the red-black-yellow-white I/O module color coding scheme that remains the standard today..

In 1982, we introduced Optomux, which quickly became the industry standard protocol..

In 1995, together with four other founding members, we formed the OPC Working Group (later the OPC Foundation) to develop interoperability standards between vendor products..

In 1998, we introduced the first commercial Ethernet I/O unit..

In 2013, we developed the groov series of products based on open source technologies (including Linux and Node-RED)..

Pay attention to quality.

Opto 22 I/O, controllers and SSRs are known for their quality and reliability.Customers often comment that their dusty, 20-year-old "Optos" are still working behind the scenes of a factory somewhere.With this level of reliability, we offer a lifetime warranty on our SSRs and most I/O modules..

Made and supported in the USA.

Since all of our products are made and individually tested at our headquarters in Temecula, California, we control quality from the ground up.That's why we also offer you free pre-sales engineering assistance, free online training, and free product support from experienced engineers..

Your advantages in automation.

Because we are engineers, we know what it's like to lose an idea because it was too difficult to implement.Designing and integrating automation systems can be frustrating.We give you a working advantage with open standards, easy-to-use software, clear documentation and how-to videos..
