Product Details:

FOXBORO FBM212 is a high-density 14-channel galvanically isolated thermocouple and millivolt differential input fieldbus module for FOXBORO Compact 200 I/A Series DCS. It receives low mV signals from multiple thermocouple types and integrates a dedicated built-in RTD channel for accurate cold junction compensation. Each channel adopts differential input design and high precision ADC to convert tiny mV signals into temperature data for the FCP controller. 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 sensor burnout and wire break faults, triggers alarms so technicians can quickly locate temperature loop issues. FBM212 supports hot swap and redundant module pair configuration, widely used for DCS maintenance, spare parts replacement and system retrofit projects. Every FOXBORO FBM212 module passes factory testing and calibration before shipment.

FBM212 is high-density thermocouple measuring card, different from 8-point FBM202 thermocouple module. Its 14 measuring points greatly save cabinet space for multi-point furnace and reactor temperature monitoring. The integrated cold junction compensation reduces measurement deviation caused by ambient temperature fluctuation. It can match P0916BV field terminal assembly and dedicated shielded cable for thermocouple wiring. It is widely used for boiler, incinerator and chemical reactor temperature monitoring in power and petrochemical plants, and can replace old high-density thermocouple input cards on legacy I/A DCS systems. Every FOXBORO FBM212 module passes factory testing and calibration before shipment.
