Woodward 9907-167 | Digital Governor Turbine Control System

Description

Woodward 9907-167 is a digital governor belonging to the 505E series, mainly used in steam turbine control systems.
Functional features:
Precise control: Advanced PID control algorithm is adopted to achieve precise control of speed, with an accuracy of up to ± 0.25%, ensuring the stability of the turbine output power.
Flexible configuration: Supports multiple control modes and parameter configurations, which can be set according to different turbine models and operating requirements to adapt to different application scenarios.
High speed processing: Based on a 32-bit microprocessor, it has high-speed data processing capabilities and can collect and process data from various input channels in real time, quickly respond to system changes, and make control decisions.
Strong communication function: Supports multiple communication protocols such as MODBUS and PROFIBUS, and can communicate with devices such as upper computers and PLCs, making it easy to integrate into complex control systems.
Fault diagnosis and protection: With fault diagnosis function, it can monitor the operating status of the system, take protective measures when detecting abnormal situations such as overspeed, overvoltage, and overtemperature, and ensure equipment safety.
Input and output: It has 2 actuator outputs, 8 relay outputs, and 6 programmable current outputs, which can be connected to various external devices to achieve control of the steam turbine.
Display and operation: Equipped with a 2-line 12 character display screen, the front panel has 30 analog buttons, and users can view and set parameters through the display screen, making operation convenient.
Working environment: The normal working temperature range is -25 ℃ to 65 ℃. If a specific frame is installed, the maximum temperature tolerance is 55 ℃. Strong anti-interference ability, highly immune to electrical interference on the power supply, with good seismic, dustproof, and waterproof performance. The optional NEMA 4X level protective casing can effectively protect internal components and is suitable for indoor and outdoor conditions.
Other features: Impact protection complies with MIL-STD-810C, method 516.2-1, program 1B, and has program upload/download capability.
