Foxboro FBM202 Thermocouple/mV Input Interface Module

Overview

The Foxboro FBM202 is a high-performance Thermocouple/mV Input Interface Module designed for use within the Foxboro I/A Series control systems. This module offers precise temperature measurement capabilities by providing eight thermocouple input channels and one isolated RTD reference junction compensation channel. Each thermocouple/mV input channel supports a wide range of thermocouple types, ensuring compatibility with various temperature ranges.

The Foxboro FBM202 also includes thermocouple burnout detection, which helps identify faulty or disconnected thermocouples. Each input channel is galvanically isolated, protecting the system from electrical noise or ground loops and ensuring reliable signal conversion and communication.

Key Features

Multiple Input Channels: Supports 8 thermocouple input channels and 1 RTD reference junction compensation channel for flexible configurations.
Wide Temperature Compatibility: Accepts standard thermocouples for diverse temperature ranges, making it suitable for a variety of industrial applications.
Thermocouple Burnout Detection: Ensures continuous monitoring and fault detection by alerting the system to thermocouple failures (up-scale burnout detection).
Galvanic Isolation: Provides electrical isolation between channels and ground, minimizing noise interference and ensuring high signal integrity.
Durable Design: Built to withstand harsh industrial environments, offering reliable performance even in challenging conditions.
