Product Description
Foxboro P0902XB Invensys I/A Series FBM42 Contact/DC Input/Output Module
Product Overview
- The Foxboro P0902XB, also known as the FBM42, is a Contact/DC 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 high-level contact and DC voltage signals for both input and output operations in industrial processes. It is used in applications such as oil and gas, chemical processing, and power generation to monitor high-voltage discrete signals (e.g., switches, relays) and control devices (e.g., high-power solenoids, actuators) within the I/A Series control system. The FBM42 is similar to the FBM41 but supports higher voltage and current ratings for more demanding applications.
