Product Details:

FOXBORO FBM201 is an 8-channel galvanically isolated analog input fieldbus module for FOXBORO I/A Series DCS system. It receives 0-20mA signals from pressure, level and flow transmitters, converting analog field readings into digital data for the DCS controller. Each channel adopts independent channel isolation and sigma-delta ADC for high precision measurement. The PCB uses conformal coating 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 loop break and signal abnormality, triggers alarms to help technicians quickly troubleshoot transmitter wiring faults. FBM201 supports hot swap and is widely used for DCS maintenance, spare parts replacement and system retrofit projects. Every FOXBORO FBM201 module passes factory testing and calibration before shipment.
