Foxboro P0400DA FBM01 I/A Series Input Module

The Foxboro P0400DA, designated as the FBM01, is an 8-channel analog input interface module for the I/A Series Distributed Control System (DCS). Each channel accepts a 2-wire analog sensor input, such as a 4 to 20 mA transmitter or a self-powered 20 mA source. The module performs the signal conversion required to interface electrical input signals from field sensors to the redundant Fieldbus. As a main-type FBM, the module independently connects to the redundant Fieldbus, ensuring continued communication even if one Fieldbus path fails. Introduced as part of the foundational I/A Series platform, the FBM01 has been widely deployed in continuous process industries for pressure, flow, level, and temperature transmitter signal acquisition.
