Foxboro (Schneider Electric)

Foxboro, founded in 1908 in Foxborough, Massachusetts, wrote foundational chapters of process control history: the company pioneered pneumatic controllers, introduced the first fully electronic distributed control system with its I/A Series in 1987, and built a measurement portfolio of differential pressure transmitters that refineries relied on for decades. After passing through Invensys, Foxboro became part of Schneider Electric's EcoStruxure Process Expert portfolio, and its I/A Series distributed control platform continues to run chemical plants, refineries, gas processing and power stations worldwide, with Schneider continuing development under the EcoStruxure Foxboro DCS branding. The Foxboro measurement line — pressure, temperature, flow and level transmitters, and magnetic flowmeters — remains in production and in service, valued for ruggedness and long calibration stability. Schneider Electric's stewardship adds cybersecurity, remote operations and analytics capabilities around the classic DCS. For plants with a legacy Foxboro installed base, the brand's continuity under a major global supplier is reassuring: migration paths, spare parts and engineering support remain available through Schneider's global channel. Foxboro thus bridges a century of control engineering heritage with current digital plant architectures.
