History

Opto 22 was founded in 1974 as a manufacturer of solid state relays. The company soon expanded its offerings to include a variety of computer-based industrial automation, remote monitoring, and data acquisition products. In 1978, Opto 22 developed the first computer-based plug-in I/O modules, and created the Yellow-Black-White-Red color scheme used to identify digital AC input, digital AC output, digital DC input, and digital DC output modules respectively. In 1982, the company created Optomux, a serial-based I/O system using the
