Woodward 8901-457 CPC-II Current-to-Pressure Converter
- Manufacturer: Woodward
- Model/Part Number: 8901-457
- Description: CPC-II Current-to-Pressure Converter, 10 bar, 4_20 mA Input, Marine-Approved, for Steam Turbine Fuel Valve Control
Overview
- The Woodward 8901-457 is a CPC-II (Current-to-Pressure Converter) designed to convert a 4_20 mA control signal into a proportional hydraulic output pressure (up to 10 bar) to position steam turbine fuel valves. It is marine-approved for use in harsh environments, such as marine propulsion, power generation, and industrial steam turbine applications, providing precise and reliable valve control.
