Foxboro DM700DZ Analog I/O Expansion Module

Product Description

The Foxboro DM700DZ is a high-density analog input/output (I/O) expansion module engineered for Foxboro I/A Series and Evo™ Distributed Control Systems (DCS). It delivers a reliable interface between field instruments—such as sensors, transmitters, and actuators—and central control processors, enabling precise data acquisition and control.

Built for industrial-grade reliability, the DM700DZ supports multiple signal types including voltage, current, RTDs, and thermocouples. With up to 32 analog input channels in a compact form factor, the module integrates easily into standard Foxboro rack systems and withstands vibration, dust, and humidity in demanding environments.

The module features redundant 24 VDC power support, optional dual-module fault-tolerant operation, and onboard diagnostics for improved system monitoring, helping to minimize maintenance downtime and enhance process visibility.
