Foxboro FBM207b P0914WH Contact Sense Input Module

The Foxboro FBM207b, part number P0914WH (also referenced as RH914WH), is a 16-channel Contact Sense Input Interface Module for the I/A Series and Foxboro Evo Distributed Control Systems. It functions as a 16-channel contact sensor, with each channel accepting a 2-wire input from a pair of dry contacts or solid-state switches. The module provides 24 V DC contact wetting voltage directly from the FBM, eliminating the need for external power supplies in contact sensing applications . Each input channel is fully galvanically isolated from other channels and ground, protecting the control system from field-side electrical faults, ground loops, and cross-channel interference. As a main-type Fieldbus Module, it independently connects to the redundant 2 Mbps Fieldbus, ensuring continued communication even if one Fieldbus path fails .
