Product Details:

FOXBORO FBM202 is an 8-channel galvanically isolated thermocouple and millivolt input fieldbus module for FOXBORO Compact 200 I/A Series DCS system. It accepts low mV signals from multiple types of thermocouples including K, J, T, R, S and B, and integrates one dedicated RTD channel for cold junction compensation. Each channel uses 16-bit sigma-delta ADC for precise temperature conversion. The PCB is conformal coated to resist vibration, dust, humidity and electromagnetic interference in harsh industrial environments. It communicates with FCP controller over redundant 2Mbps fieldbus. Built-in continuous self-diagnosis detects thermocouple burnout and circuit faults, triggers alarms for technicians to quickly locate wiring issues. FBM202 supports hot swap and is widely used for DCS maintenance, spare parts replacement and system retrofit projects. Every FOXBORO FBM202 module passes factory testing and calibration before shipment.

FBM202 is specially designed for high-temperature thermocouple measurement, equipped with built-in cold junction compensation to eliminate manual compensation wiring errors. Its channel-to-channel isolation prevents cross-channel noise interference in multi-point furnace temperature monitoring. It supports burnout detection to alert operators when thermocouple wires break, avoiding misleading temperature readings. It is widely used in boiler, incinerator and high-temperature reactor temperature monitoring and serves as spare replacement for legacy I/A DCS thermocouple input cards. Every FOXBORO FBM202 module passes factory testing and calibration to guarantee reliable process control performance.
