Collection: Honeywell TDC 2000/3000 Series

Legacy systems that still power critical processes. The Honeywell TDC 2000/3000 series distributed control systems (DCS) were the workhorses of industrial automation for decades - and many are still running today in refineries, chemical plants, and power facilities worldwide. While Honeywell has transitioned to the advanced Experion PKS platform, we provide the replacement parts, modules, and expertise to keep your TDC systems operational. Whether you need immediate spares or are planning a phased migration to Experion, we support both your current operations and your future upgrade path.
