Foxboro FBM238 P0927AF High-Density Discrete I/O Interface

Product Description

Integrated Discrete I/O for Foxboro DCS Environments

The Foxboro FBM238 (Part Number P0927AF) is a high-density Discrete Input/Output module designed for the I/A Series and EcoStruxure Foxboro Distributed Control System (DCS). This module provides a dual-function interface, featuring 24 discrete input channels for voltage monitoring and 8 discrete output channels for switching field devices. By combining input monitoring and output control into a single unit, the FBM238 optimizes rack space and simplifies the control architecture for complex process automation tasks.

Industrial-Grade Reliability and Precision

Engineered to operate in the most demanding industrial sectors, the FBM238 P0927AF supports Sequence of Events (SOE) recording with millisecond resolution, allowing engineers to track the exact timing of status changes for critical safety interlocks and alarms. Each channel is galvanically isolated from the system bus to ensure signal integrity and protect internal DCS circuitry from field-side transients. With a ruggedized hardware design rated for temperatures ranging from -40 °C to +70 °C, this module is specifically built for long-term deployment in harsh, unconditioned environments common in oil, gas, and power generation facilities.
