Product Details:

FOXBORO DM900HU, also known as FBM26, is a high-performance DC voltage input module for FOXBORO I/A Series DCS system, designed for collecting DC discrete voltage signals in heavy industrial environments. This module adopts conformal coated PCB and reinforced metal shielding, protecting internal electronic components from vibration, dust, humidity and electromagnetic interference. It adopts plug-in rack mounting and connects to the rack backplane bus to transmit field digital signals to DCS processor. It acquires 24VDC discrete input signals from field switches and contact sensors for oil & gas, chemical, power and pulp & paper industries. Built-in continuous self-diagnosis function monitors circuit and communication status in real time, triggers alarm once faults detected, helping maintenance staff locate faults quickly and reduce unplanned plant downtime. This I/O module is widely used for system maintenance, spare parts replacement and DCS retrofit projects. Every FOXBORO DM900HU module passes strict factory testing and calibration before shipment to guarantee stable and reliable operation.
