Product Details:

FOXBORO FBM207C is a 16-channel galvanically isolated 48VDC contact sensing discrete input fieldbus module of FOXBORO Compact 200 I/A Series DCS. It supplies built-in 48VDC wetting voltage to detect open and closed status of field mechanical contacts, such as breaker auxiliary contacts, valve limit switches and safety interlock switches. Each channel has independent channel-to-channel and channel-to-ground isolation up to 600V. The module features configurable debounce time (4ms,8ms,16ms,32ms) to filter contact bounce noise and avoid false state triggers. The PCB adopts 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 circuit faults and abnormal channel status, triggers alarms for technicians to quickly locate wiring or switch failures. FBM207C supports hot swap and redundant module pair configuration, widely used for DCS maintenance, spare parts replacement and system retrofit projects. Every FOXBORO FBM207C module passes factory testing and calibration before shipment.

FBM207C is the 48VDC contact sensing model of FBM207 family, different from FBM207 wide voltage version and FBM207B 24VDC variant. Its higher 48V wetting voltage works well for contact points with high contact resistance caused by oxidation or dust, maintaining stable status detection. It can match dedicated termination assemblies like RH917GY for complete signal connection. It is commonly used for high-reliability safety interlock and shutdown system status feedback in petrochemical and power plants, and serves as direct replacement for aging 48V contact input cards on legacy I/A DCS systems. Every FOXBORO FBM207C module passes factory testing and calibration to guarantee reliable process control performance.
