Introduction to WOODWARD 9907-1200
9907-1200 Product Overview
The WOODWARD 9907-1200, widely recognized as the CPC-II (Current-Pressure Converter II), is a high-performance electro-hydraulic interface module engineered for industrial turbine and hydraulic control systems. As a critical bridge between electronic controllers and hydraulic actuators, it specializes in converting standard 4-20mA current signals into proportional, stable pressure outputs—directly driving steam/gas turbine valves, pipeline control valves, and servo systems to ensure precise regulation. This module is a trusted replacement for legacy models like 9907-1105 and 9907-1100, widely deployed in power plants (for generator frequency stabilization), oil & gas pipelines (for valve control), and marine propulsion systems. Its rugged IP67-rated housing resists oil contamination (complying with ISO 20/16 standards) and extreme temperatures, while a 100,000-hour MTBF ensures long-term reliability. Fully compatible with WOODWARD 505/505E governors, it supports diverse communication interfaces for seamless integration into DCS platforms, enabling remote monitoring and calibration.
