Product Details:

FOXBORO FBM201C is an 8-channel galvanically isolated analog input fieldbus module of FOXBORO Compact 200 I/A Series DCS. It accepts 0-5VDC voltage signals from voltage transmitters, potentiometers and displacement sensors. Each channel uses independent sigma-delta ADC to convert voltage readings into digital data for FCP controller. The PCB is conformal coated to resist vibration, dust, humidity and electromagnetic interference in harsh industrial environments. It communicates over redundant 2Mbps fieldbus. Built-in continuous self-diagnosis detects open circuit and over-range voltage faults, triggers alarms so technicians can quickly troubleshoot sensor wiring issues. FBM201C supports hot swap and is widely used for DCS maintenance, spare parts replacement and system retrofit projects. Every FOXBORO FBM201C module passes factory testing and calibration before shipment.

FBM201C is designed for direct 0-5V voltage signal acquisition, differing from FBM201 current and FBM201B millivolt versions. Its high input impedance avoids loading effects on low-power voltage transducers. Channel-to-channel isolation eliminates ground loop noise between different measurement points. It is commonly used for valve position feedback and linear displacement monitoring on refining and power plant DCS systems, and acts as spare replacement for legacy I/A DCS voltage input cards. Every FOXBORO FBM201C module passes factory testing and calibration to guarantee reliable process control performance.
