Control Technology Inc. designs and manufactures process control and factory automation equipment. Founded in 1980 and based in Knoxville, Tennessee, the company originally produced specialty modules for TI, Omron, Allen-Bradley and Siemens, including what was the automation market’s first TCP/IP module. Today, CTI develops its own line of process control products aimed at manufacturers worldwide, emphasizing systems that are straightforward to operate, easy to integrate, and reliable across successive generations.

Its offerings include control solutions that remain compatible with the TI/Siemens 505 PLC lineage and integrate with a range of motors, drives, and HMI/SCADA systems. The Janus PAC line is designed to maintain backward compatibility with 505-series equipment while providing modern programming and communications capabilities to support sustainable operations and long-term system life. In 2021 the company announced a 16-channel isolated RTD input module for its 2500 Series Classic I/O.
