WOODWARD 9907-167 servo controller

Product Overview:
WOODWARD 9907-167 is a high-performance digital speed controller belonging to the WOODWARD 505E series. It is designed based on a 32-bit microprocessor and is specifically designed for managing the speed, load, and start/stop processes of industrial steam turbines, gas turbines, water turbines, and other equipment.

Main features and advantages
High precision control: adopting advanced PID control algorithm, the speed control accuracy is as high as ± 0.25%, the response time is less than 14 milliseconds, and it can adapt to complex working conditions.
Multiple control modes: Supports isochronous control, Droop control, load sharing, and Isochronous control to meet the needs of different application scenarios.
Automatic start and stop management: equipped with automatic start sequence and critical speed avoidance function, supporting emergency stop protection.
Powerful communication function: supports multiple communication protocols such as MODBUS, PROFIBUS, Ethernet, etc., and can be seamlessly integrated with DCS, PLC, SCADA systems.
Human computer interface friendly: equipped with an 8.4-inch LCD screen, supporting real-time monitoring, historical data recording, and trend analysis.
High reliability design: using industrial grade components, with a wide temperature range design (-40 ° C to+85 ° C), IP67 protection level, and strong electromagnetic interference resistance.
Flexible input/output interface: Supports 4-20 mA current signal or 1-5 V voltage signal input, providing 0-10 V DC analog output or relay output.
