Product Details:

FOXBORO FBM19 is an 8-channel 4-20mA analog output fieldbus module for FOXBORO I/A Series DCS system. It receives control output values from the DCS controller and converts digital signals into 4-20mA analog signals to drive positioners, analog transmitters and variable signal indicators. This module adopts galvanic channel isolation and conformal coated PCB, protecting electronic components from vibration, dust, humidity and electromagnetic interference in harsh industrial environments. It communicates with DCS controller over redundant HDLC fieldbus. Built-in continuous self-diagnosis monitors signal open circuit and output faults, triggers alarms for technicians to quickly locate wiring and instrument issues and reduce plant downtime. FBM19 supports hot swap and is widely used for DCS maintenance, spare parts replacement and system retrofit projects. Every FOXBORO FBM19 module passes factory testing and calibration before shipment.

FBM19 generates standard 4-20mA analog control signals for valve positioners, the core control interface for regulating control loops. Each channel can independently set output values, delivering precise modulation of control valves to adjust pressure, flow and liquid level. Its high accuracy analog output ensures stable closed-loop control for continuous process plants, and serves as direct spare replacement for aging analog output cards on legacy I/A DCS systems. Every FOXBORO FBM19 module passes factory testing and calibration to guarantee reliable process control performance.
