Product Description
Foxboro P0904BS Invensys I/A Series FBM204 Analog Input/Output Module
Product Overview
- The Foxboro P0904BS, also known as the FBM204, is an Analog Input/Output Module from the Invensys I/A Series (now part of Schneider Electric's EcoStruxure Foxboro DCS). This module is designed to interface with analog field devices, such as sensors and actuators, to acquire and process 0–20 mA signals (including 4–20 mA) for both input and output operations. It is used in industrial automation applications, including oil and gas, chemical processing, and power generation, for precise process monitoring and control within the I/A Series control system.
