WOODWARD 9907-1106 Current Pressure Converter CPC-II

WOODWARD 9907-1106 is a high-performance servo valve controller that occupies an important position in the field of industrial automation control. With advanced technology and reliable performance, it is widely used in the control systems of power equipment such as steam turbines, gas turbines, and large industrial engines.

Its design purpose is to achieve precise control of servo valves, thereby regulating key parameters such as fuel quantity and steam intake of power equipment, ensuring that the equipment can maintain a stable and efficient operating state under different working conditions. Whether in industries such as power production, petrochemicals, or marine power, this controller can play a key role, providing strong support for the safe and stable operation of industrial production.

• 
  

• Power Supply Parameters: It adopts 24V DC power supply, with an operating voltage range of 20-30V DC, which can adapt to certain fluctuations of the power supply voltage in industrial sites and ensure stable power supply for the controller. The power consumption is low, with a typical value of 15W, which saves energy and reduces its own heat generation, helping to extend the service life of the equipment.

• 
  

• Control Signal Input: It supports various analog input signals, including 4-20mA, 0-10V, etc. These signals can come from upper computers or other control equipment and are used to provide control commands. In terms of input impedance, the current signal input impedance is 250Ω, and the voltage signal input impedance is 10kΩ, ensuring accurate reception of external control signals.

• 
  

• Output Signal: The output signal is current-type, with a range of 4-20mA, used to drive the action of the servo valve. The output accuracy is high, with an error not exceeding ±0.1% of the full scale, which can precisely control the opening of the servo valve and ensure accurate regulation of power equipment parameters. The output load capacity is 50-500Ω, which can be adapted to various types of servo valves.

• 
  

• Environmental Parameters: The operating temperature range is -40℃ to 70℃, enabling it to work normally in extreme industrial environments such as severe cold and high temperatures; the relative humidity is 5%-95% (non-condensing), which can adapt to humid working environments, such as ship engine rooms. It has good anti-vibration performance, capable of withstanding vibrations with a frequency of 10-2000Hz and an acceleration of 10g, and the anti-impact performance reaches 50g, ensuring stable work under vibrations and impacts generated during equipment operation.

• 
  

• Response Time: The response time of the control signal is less than 5ms, which can quickly respond to input commands and adjust the servo valve in a timely manner, ensuring the rapid stabilization of power equipment parameters and improving the dynamic performance of the system.

• 
  

• High-Precision Servo Control: WOODWARD 9907-1106 adopts advanced control algorithms, which can perform high-precision control on the servo valve, making the opening of the servo valve highly consistent with the input control signal. Through precise control of the servo valve, it can accurately regulate the fuel supply, steam intake, etc. of power equipment, thereby achieving precise control of parameters such as equipment speed and load, and improving the operating efficiency and control accuracy of the equipment.

• 
  

• Comprehensive Self-Diagnosis Function: It has strong self-diagnosis capability, which can real-time monitor its own working status, including power supply voltage, internal circuit working conditions, connection status with the servo valve, etc. When an abnormality is detected, it will promptly issue a fault alarm signal and record fault information such as fault type and occurrence time through the internal storage unit, providing an accurate basis for maintenance personnel to troubleshoot and shortening the fault handling time.

• 
  

• Good Anti-Interference Ability: It adopts multiple anti-interference designs, including power supply filtering, signal isolation and other technologies, which can effectively resist electromagnetic interference, radio frequency interference, etc. in industrial sites. Even in complex electromagnetic environments, it can ensure the stable transmission of control signals and the normal operation of the controller, avoiding the decline of control accuracy or equipment misoperation caused by interference.

• 
  

• Flexible Parameter Configuration: It provides a convenient parameter configuration interface, and users can set various parameters of the controller through special software or panel buttons, such as input signal type, output signal range, control gain, etc. According to different servo valve models and control requirements, parameters can be flexibly adjusted to achieve the best matching between the controller, the servo valve and the entire control system, improving the adaptability of the system.

• 
  

• Reliable Redundancy Design: Some models have redundancy function and can be configured into a dual-machine hot standby mode. When the main controller fails, the standby controller can automatically switch to operation without disturbance, ensuring the continuity of servo valve control, improving the reliability of the entire control system, and is especially suitable for occasions with extremely high safety requirements, such as nuclear power plants and large chemical plants.
