FOXBORO FBM202 P0926EQ – Isolated Thermocouple/mV Input Field Module
Product Overview
The FOXBORO FBM202 P0926EQ is an 8-channel isolated field input module engineered for Foxboro I/A Series distributed control systems. It specializes in collecting thermocouple and millivolt signals from field industrial sensors, delivering accurate temperature and low-voltage process data to the main control system. This hardware solves common industrial pain points including signal crosstalk, inaccurate temperature sampling and weak anti-interference performance in process environments. With built-in cold junction compensation and full channel isolation design, it maintains stable data acquisition for chemical, power and oil & gas process control loops.

Installation and Maintenance
Install the module on a standard I/A Series rack and lock the fixed bracket to ensure stable backplane connection. Complete field thermocouple wiring strictly following channel specifications to avoid reverse connection or short circuit. Keep the installation area dry and ventilated to prevent dust accumulation on circuit boards. Conduct routine inspection of terminal tightness and signal stability every quarter. Perform professional calibration annually to sustain long-term sampling accuracy, and replace aging modules promptly to avoid data deviation.
