Description
Product Description
The Foxboro FBM202 (P0926EQ) is an 8-channel thermocouple and millivolt (mV) analog input module tailored for the Foxboro I/A Series Distributed Control System (DCS). It delivers precise temperature measurements by accepting a wide variety of standard thermocouple types (J, K, T, etc.) and low-level mV signals. Each input channel is galvanically isolated, ensuring high noise immunity and preventing interference between channels.
A dedicated isolated RTD reference junction channel provides accurate cold-junction compensation for thermocouple inputs, enhancing overall measurement reliability. The module employs high-accuracy sigma-delta A/D conversion, making it ideal for critical temperature-monitoring applications in oil refining, chemical processing, power generation, and other industrial sectors requiring precise thermal control.
The FBM202 supports both baseplate and DIN-rail termination assemblies, and its rugged design withstands harsh environmental conditions. The module is hot-swappable and field-replaceable, allowing seamless maintenance without disrupting system operation.
