Woodward | 9907-1200 | CPC-II Current to Pressure Converter
The 9907-1200 CPC-II is an electrohydraulic pressure-regulating valve control designed for precise steam turbine valve control. It uses an accurate internal pressure sensor and a PID controller to regulate the positioning of single-acting steam turbine governor valves.
Features
- Pressure Control: Accepts a 4–20 mA pressure demand signal to accurately control oil pressure and position single-acting steam turbine governor valves.
- Redundancy: Configurable to accept redundant pressure demand inputs from one or two controllers.
- Failsafe Mechanism: Internal valve-return-spring forces the CPC to a failsafe position, ensuring safe closure of turbine control valves in the event of an internal unit failure.
- Robust Design: Features a strong actuator, corrosion-resistant materials, a single moving rotary valve, and a self-cleaning port design.
Specifications
- Dimensions: 163 × 38 × 58 mm
- Weight: 0.35 kg
- Input Voltage: +24 VDC at 1 A
- Operating Temperature Range: -40°C to 70°C
- Humidity Standards: 20 to 55°C at 95% for 48 hours
- Display Type: Two-line x 24 characters
- Enclosure Type: IEC 60529, IP56
