Descripción

Overview

The Foxboro AD207AU is a high-density analog input module for Foxboro I/A Series DCS, providing up to 32 analog channels for versatile signal acquisition. It supports voltage, current, RTDs, and thermocouples, delivering precise measurements for large-scale automation and continuous process monitoring in demanding industrial environments.

Operating Principle

The AD207AU integrates analog signal conditioning, high-accuracy A/D conversion, and communication within a compact, rugged module. Each input channel can be configured for the specific sensor type, offering flexibility across diverse automation setups. Redundant 24 VDC power and optional dual-module fault-tolerant configurations enhance reliability for mission-critical systems. Some supplier sub-variants are listed as dual-channel analog isolator/converters, offering rapid response and DIN-rail mounting for specialized applications.
