FBM207b P0916JS I/O Interface Module

The Foxboro FBM207b, part number P0916JS, 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 for contact sensing applications. Each input channel is galvanically isolated, protecting the control system from field-side electrical faults and ground loops. As a main-type Fieldbus Module, it independently connects to the redundant 2 Mbps Fieldbus, ensuring continued communication even if one Fieldbus path fails. The FBM207b is widely deployed in oil and gas, chemical processing, power generation, and water treatment facilities for equipment status monitoring, alarm handling, and sequence-of-events recording.
