Opto 22 manufactures hardware and software products that link all kinds of electrical, mechanical, and electronic devices and machines to networks and computers.

Opto 22 controllers, I/O (input and output modules), solid-state relays, and software are used for industrial automation, remote monitoring, data acquisition, and machine-to-machine (M2M) applications.

Opto 22 products make it possible for you to use your normal business computer systems to monitor, control, and get data from all the devices and machines that are important to your business.

Opto 22 products translate the data between computers and other machines. This translation works easily and inexpensively because Opto 22 designs its products to run on non-proprietary communication standards like Ethernet and the Internet Protocol (IP).

Atel Electronics is a distributor of Opto 22 products in Poland.
