8440-2082 Functional Description 

The Woodward 9907-1200 CPC-II Current-To-Pressure Converter is a specific model of the CPC-II (Current-to-Pressure Converter), an electrohydraulic control module designed for demanding industrial environments. It operates as a critical interface, converting a standard (4 to 20) mA electrical input signal into a precise and stable 10-bar hydraulic control pressure. This core functionality makes the module essential for accurately positioning steam and fuel valves, as well as controlling single-acting servos on steam turbines, ensuring reliable and efficient turbine operation.

Engineered for both performance and serviceability, the 9907-1200 Woodward Electro-hydraulic converters integrates key components like a brushless actuator, a rotary hydraulic valve, and a pressure sensor within a robust housing. This compact design allows for direct manifold mounting, simplifying installation. The electronic PCB assembly is easily accessed by removing the top cover, facilitating straightforward wiring and maintenance. These features highlight the practical design philosophy behind the module.

For configuration and real-time tuning, the CPC-II Current-To-Pressure Converter Woodward 9907-1200 Woodward is supported by a PC-based service tool. This allows for dynamic adjustments to optimize its performance within the control loop. The device is certified for use in Zone 2 hazardous areas, confirming its suitability for challenging operational environments. The reliability of the module is a cornerstone of its design, ensuring long-term stability in critical control applications.

As a simplex (non-redundant) unit, the PLC Module 9907-1200 Woodward provides a high-integrity solution for a wide range of turbine control needs. Its precise pressure regulation is fundamental to maintaining safe and efficient turbine operation. For applications requiring higher availability or safety certifications, Woodward offers fully redundant models, but the standard 9907-1200 PRESSURE REGULATING VALVE CONTROL remains a versatile and trusted component in industrial automation and power generation systems worldwide.
