Description

Woodward  9907-014  Full Permission Speed Control Module

Functional characteristics
Precise speed control: By connecting to a speed sensor, it receives speed signals from the engine or turbine, compares them with the set reference speed, and uses advanced control algorithms to calculate the adjustment amount, precisely regulating the equipment’s rotational speed to maintain it within the required range, ensuring the efficient and safe operation of the equipment.
Compatibility with multiple speed sensors: It can be connected to various types of speed sensors such as optical sensors and magnetic sensors, and can be flexibly selected according to the type of turbine and environmental conditions to adapt to different application scenarios.
Rich communication interfaces: Supports communication protocols such as TCP/IP, OPC, and Modbus, enabling data exchange with the central control system to achieve remote monitoring, diagnosis, and control adjustment. This facilitates users’ remote operation and management, and also facilitates interaction with other systems such as factory DCS and HMI.
Fast control cycle: Critical control cycles can be processed within 5 milliseconds, enabling rapid response to speed changes and timely adjustments to ensure the timeliness and effectiveness of control.
The unique rate group structure: By adopting a unique rate group structure, it ensures that the control functions operate deterministically according to the rate group defined by the application engineer, preventing the addition of new code to change the system dynamics, and making the control deterministic and predictable.
Flexible input and output: For critical control signals, synchronous input and output (I/O) can be used. Distributed I/O can be applied to other less critical parameters, allowing for flexible configuration of input and output to meet different control requirements.
Digital control technology: By adopting digital control technology, it offers flexible control logic and parameter configuration capabilities. Users can view and adjust system variables through the service interface, facilitating personalized Settings and maintenance.
It has protection functions: It is equipped with multiple protection functions such as overload protection, overvoltage protection and overspeed protection, which can take protective measures in time when the equipment operates abnormally to ensure the safe operation of the equipment.
Data recording and analysis: It usually has the functions of data recording and analysis, which can record the operation data of the equipment, helping users analyze the operation status of the equipment and optimize the operation and maintenance strategies.

Application field
