Product Details:

FOXBORO AD198GV is a rack-mounted analog input module for FOXBORO I/A Series DCS system, a high-performance DCS signal card built for process automation. This analog input module is a plug-in PCB card assembled with precision electronic circuits, equipped with shielding structure to protect internal components from vibration, dust and electromagnetic interference inside industrial control cabinets. It can be directly installed on the DCS rack backplane, supporting fast installation and convenient maintenance. The hardware is designed for continuous long-term operation in heavy industrial control rooms to collect analog measurement signals from field instruments.

This FOXBORO AD198GV DCS signal card receives analog current and voltage signals from field transmitters for temperature, pressure, flow and liquid level measurement. It converts raw analog field signals into digital data and transmits processed data to the DCS host controller for real-time monitoring, historical recording and closed-loop PID control calculation. Each channel supports independent signal conditioning, which effectively reduces signal distortion and measurement deviation. The module integrates built-in channel fault diagnosis function, which can detect open circuit, short circuit and hardware abnormality. Once faults are detected, the module sends alarm information to the DCS host system, helping maintenance engineers quickly locate faults and reduce unplanned production 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.
