PLC Module P0400DA FBM01

The Foxboro P0400YD, designated as the FBM03, is an 8-channel Resistance Temperature Detector (RTD) input interface module for the I/A Series Distributed Control System (DCS). It is specifically designed to accept Platinum and Nickel RTD sensors, performing the signal conversion required to interface the electrical resistance signals from field RTDs to the redundant Fieldbus. Each channel supports 2-, 3-, or 4-wire RTD configurations within a 0 to 320 ohm resistance range. The FBM03 executes an Analog Input application program with configurable options for Analog Input Resolution, Fieldbus Switching Enable, and Fieldbus Switching Time. As a main-type FBM, it independently connects to the redundant Fieldbus, ensuring continuous communication even if one Fieldbus path fails .

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.
