Foxboro P0400DA FBM Analog Input Module 8 Channels

Product Overview

The Foxboro P0400DA is an analog input Fieldbus Module designed for the Foxboro I/A Series DCS platform. Moreover, it provides stable and accurate acquisition of current loop signals from field instruments in continuous process environments.

This module supports eight independent 0–20 mA analog input channels, allowing efficient integration of multiple transmitters within a compact footprint. Therefore, it plays a critical role in reliable data collection for distributed control systems.

Each channel accepts two-wire analog sensor inputs, which simplifies field wiring and reduces installation complexity. In addition, the module architecture supports long-term operation in electrically noisy industrial environments.

Although discontinued by the original manufacturer, this model remains widely deployed in legacy I/A Series systems. Therefore, it is commonly sourced for system expansion, maintenance, and lifecycle replacement projects.
