AD202MV analog input module for Foxboro I/A Series DCS, 8-channel thermocouple and mV signal acquisition, channel isolation, replacement spare part for process automation.

Product Overview

• Part No: AD202MV
• Brand: FOXBORO
• Category: I/A Series Thermocouple Millivolt Analog Input Module

AD202MV is an 8-channel low-level analog input module for Foxboro I/A Series distributed control system. It is designed to acquire millivolt signals and multiple types of thermocouple temperature signals from field sensors. It converts weak analog signals into digital data for controller calculation and monitoring. It supports channel-to-channel isolation to reduce interference in industrial environments. It adopts single-slot rack mounting structure, widely used for DCS maintenance, system retrofit and upgrade projects.
