FBM204 P0914SY I/O Interface Module

The Foxboro FBM204, part number P0914SY, is a compact 4-channel isolated analog Input/Output module for the I/A Series and EcoStruxure Foxboro Distributed Control Systems. It combines four 0-20 mA analog input channels and four 0-20 mA analog output channels on a single Fieldbus Module, enabling simultaneous process measurement and final control element actuation from one rack slot . As a main-type Fieldbus Module, the FBM204 independently connects to the redundant 2 Mbps Fieldbus, ensuring continued communication even if one Fieldbus path fails. The module is widely deployed in oil and gas, chemical processing, power generation, and water treatment facilities for analog control loops where both monitoring and actuation are required in close proximity .
