Located in Tennessee, USA, CTI has been designing and manufacturing industrial automation products since 1980 at its Knoxville facility.

Since the beginning of the 2000s, thanks to its SERIE 2500®, CTI has ensured the durability of the TI505® and SIMATIC®505 ranges in complete transparency for its industrial users, since the production of these ranges has been stopped by the original manufacturers.

The 2500® Series is a compatible replacement for older Simatic® 505 automation systems, while incorporating many enhancements in functionality and performance.

The 2500 Series products include a full range of CPUs, power supplies, bases, remote base controllers, digital and analog I / O and many communication solutions.

CTI 2500 Series products are constantly evolving and are installed in factories of large industrial companies worldwide.
