Product Details:

FOXBORO AD202MV is a high-precision rack-mounted analog input module compatible with FOXBORO I/A Series DCS system, a reliable DCS signal card built for process automation. This module adopts conformal coated PCB assembly and reinforced shielding frame, protecting internal precision electronic circuits from vibration, dust and electromagnetic interference inside industrial control cabinets. It can be plugged directly onto the DCS rack backplane and matched with dedicated terminal base for convenient wiring and fast maintenance. The hardware is designed for stable long-time continuous operation in heavy industrial control rooms to collect various analog field signals.

This FOXBORO AD202MV DCS signal card receives multiple types of analog signals from field transmitters used to measure temperature, pressure, flow and liquid level, including 4~20mA DC current, DC voltage, RTD and thermocouple signals. It converts raw analog field signals into digital data and transmits processed digital data to the DCS host controller for real-time monitoring, historical trend recording and closed-loop PID control calculation. Every channel is equipped with independent galvanic isolation to eliminate cross-channel signal crosstalk and guarantee high-precision data acquisition. The module integrates built-in channel self-diagnosis function, which can detect open circuit, short circuit and hardware abnormalities. Once faults are detected, it sends alarm information to the DCS host system, helping maintenance engineers quickly locate faulty channels and reduce unplanned plant downtime. It supports hot swap operation, technicians can replace the module without shutting down the whole DCS system, which is critical for continuous production plants.
