The FOXBORO RH914TR (also known as FBM217) is a 32-channel discrete (digital) input module for the Foxboro I/A Series (Schneider Electric) distributed control system (DCS). It serves as a critical interface for acquiring on/off (discrete) signals from field devices such as switches, pushbuttons, and solenoid valves. Featuring optical isolation and support for multiple voltage levels, it ensures reliable signal detection and electrical protection in industrial environments
