Product Details:

FOXBORO DM400YR, also known as FBM15, is a 120VAC I/O expander module for FOXBORO I/A Series DCS system, used to expand discrete signal channels for field control equipment in heavy industrial environments. This module adopts conformal coated PCB and metal shielding housing, protecting internal electronic components from vibration, dust, humidity and electromagnetic interference. It is plug-in rack design and connects to rack backplane bus to expand I/O capacity of main FBM modules. It supports 120VAC digital input and output signal expansion 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 expander module is widely used for system maintenance, spare parts replacement and DCS retrofit projects. Every FOXBORO DM400YR module passes strict factory testing and calibration before shipment to guarantee stable and reliable operation.
