Reliable hardware, easy-to-use software, and people you can talk to.
We make automation simple.

Opto 22 manufactures products for industrial automation, remote monitoring, data acquisition, process control, discrete manufacturing, energy monitoring, and SCADA.

Our products include industrial I/O systems, programmable automation controllers (PACs), industrial control software, and solid state relays.

Industrial I/O Systems—SNAP I/O processors with distributed intelligence offer a more efficient system. SNAP I/O modules for analog control and digital control are guaranteed for life.

Programmable Automation Controllers (PACs)—PACs merge the best features of industrial PLCs, DCSs, RTUs, and PCs. Featuring industrially hardened construction, distributed intelligence, communication options, and open standards, PACs are suited to all kinds of industrial control and monitoring applications.

Industrial Control Software—Easy-to-use flowchart-based control software, a full-featured HMI, and OPC and database connectivity. See the PAC Project software suite.

Solid state relays (SSRs)—SSRs are the workhorses of the modern world, and ours are famous for their reliability. Most Opto 22 SSRs are guaranteed for life.
