Introduction to WOODWARD 9907-164
Product Overview
The WOODWARD 9907-164 is a high-performance microprocessor-based digital controller, serving as a core component in the brand’s 505 series for industrial turbine and generator control. It integrates advanced adaptive PID algorithms, multi-channel data acquisition, and comprehensive safety mechanisms to deliver precise speed and load regulation for rotating equipment under dynamic working conditions. Widely applied in power generation, oil & gas, and marine engineering, it governs steam and gas turbines in thermal plants to maintain grid frequency stability, controls turbine-driven compressors in oil pipelines for optimal pressure, and manages propulsion systems in offshore platforms. Its rugged design features an IP56-rated aluminum alloy housing, withstanding salt spray, high humidity, and vibrations in harsh industrial environments. Seamlessly compatible with WOODWARD CPC-II electro-hydraulic converters and ProTech protection systems, it supports Modbus and optional Ethernet protocols, enabling smooth integration into DCS/SCADA platforms for remote monitoring and diagnostics.
The WOODWARD 8237-2597 is a versatile digital regulator, serving as a key control component in the brand’s 820 series for industrial automation systems. It integrates multi-algorithm control logic, comprehensive I/O processing, and intuitive operation features to deliver precise parameter regulation for power generation and industrial process control applications. Widely applied in thermal power plants, chemical processing lines, and turbomachinery systems, it stabilizes operational parameters of boiler feedwater pumps, optimizes fuel supply for industrial furnaces, and ensures consistent output of small-scale turbogenerators. Its rugged structural design with dust-proof and water-resistant properties adapts to harsh industrial environments like control rooms and workshop equipment bays. Seamlessly compatible with WOODWARD 2301 series controllers and Varistroke actuators, it supports mainstream communication protocols such as Modbus and Profibus, enabling smooth integration into DCS systems for centralized monitoring and remote diagnostics.
