مقدمة المنتج
The وودوارد 9907-1200 CPC-II (Current to Pressure Converter) is a high-performance electro-pneumatic transducer designed for precise valve actuator control in industrial, power generation, and turbine control applications. It translates electrical current input signals into proportional pneumatic output, enabling accurate valve positioning for optimal engine or turbine performance.
The CPC-II model is the successor to وودوارد’s original CPC line, with advanced features, higher reliability, and broader compatibility with electronic control systems. Built to withstand harsh operating environments, it supports high-speed response, excellent repeatability, and flexible installation options.
This converter is typically used in conjunction with وودوارد controllers such as the 505, 723, and Micronet systems, forming a core part من closed-loop turbine control architectures.
