The only legacy we leave with customers is our dedication and innovation

Using bridge solutions and a phased approach, PCT designs and implements legacy upgrades that enable you to integrate the latest in controllers, drive systems, and HMIs while allowing you to retain and use your existing I/O and other systems – delivering heightened manufacturing performance.  Upgrades benefit your operations by improving reliability, increasing productivity, minimizing downtime, and by reducing the time and expense required to locate and purchase antiquated spare parts.  Among PCT’s many specialties are upgrades for Automax Controls and Reliance Drives to current Siemens and Rockwell platforms.
