Introduction to WOODWARD 9907-1199
9907-1199 Product Overview
The WOODWARD 9907-1199 is a dedicated I/O expansion module, specifically engineered to extend the signal processing capability of the brand’s 505E turbine control system. It serves as a critical interface between the central controller and distributed field devices, integrating high-density analog and digital channels to support additional sensors, actuators, and safety switches in complex industrial setups. Widely deployed in power plants, petrochemical refineries, and offshore turbine systems, it expands the monitoring range of steam turbine vibration sensors, adds control channels for gas turbine fuel valves, and integrates safety interlocks for turbogenerator systems. Its rugged design features a metal housing with IP54 protection, resisting industrial dust, humidity, and vibration, while optical isolation between channels prevents signal interference. Fully compatible with WOODWARD 505E governors and ProTech protection modules, it communicates via the brand’s proprietary LONworks protocol, ensuring seamless data synchronization with the central control system for enhanced operational visibility.
