Description
Overview
The Foxboro AD202MR is a pneumatic control module designed for proportional regulation within Foxboro I/A Series distributed control systems. It is ideal for environments where pneumatic operation is preferred over electrical signals, including hazardous locations, explosion-risk areas, or remote sites without reliable power.
Operating Principle
The AD202MR employs a force-balance mechanism to provide precise and stable control. It receives a standard pneumatic input signal and generates a proportional output to drive valves or other pneumatic actuators. The design ensures consistent loop performance while eliminating the need for electrical power.
