Introduction to WOODWARD 9907-1183
9907-1183 Product Overview
The WOODWARD 9907-1183 is a dedicated safety logic control module, serving as a critical protection component in the brand’s 505 series turbine control systems. It specializes in real-time fault monitoring and emergency interlock control, integrating high-speed signal processing circuits and redundant logic units to ensure reliable shutdown or load reduction when abnormal conditions occur. Widely applied in thermal power plants, petrochemical refineries, and offshore turbine systems, it monitors key parameters like turbine vibration, bearing temperature, and oil pressure, triggering immediate protective actions to prevent equipment damage. Its rugged design features a double-layer metal housing with EMI shielding, adapting to high-vibration and electromagnetic interference environments. Fully compatible with WOODWARD 505E controllers and ProTech protection systems, it supports Modbus and Ethernet communication for seamless integration into DCS networks, enabling operators to track fault logs and safety events remotely.
