WOODWARD 5466-425 Analog I/O Module

WOODWARD 5466-425 is a high-performance controller specially designed for industrial power equipment control, and is widely used in the control systems of diesel engines, gas engines and other equipment.

• 
  

• Power Supply Parameters: It adopts 24V DC power supply, with an operating voltage range of 18-32V DC, which can adapt to fluctuations in the power supply voltage in industrial sites and ensure the stable operation of the controller. The power consumption is low, with a rated power consumption of about 12W, which reduces energy consumption and at the same time reduces its own heat generation, which is conducive to extending the service life of the equipment.

• 
  

• Control Input and Output: It has 4 analog input channels, which can receive 4-20mA or 0-10V signals for collecting sensor data such as engine speed, temperature, and pressure; it has 2 analog output channels with an output range of 4-20mA for controlling external devices such as actuators. There are 8 digital input channels and 6 digital output channels, which meet the connection needs with various switching devices and realize logical control functions.

• Control Precision: The speed control precision can reach ±0.2% of the rated speed, which can accurately maintain the stability of the engine speed and avoid affecting the operating efficiency of the equipment due to speed fluctuations; the load control precision is ±1%, which can accurately adjust the output load of the engine to adapt to different load changes.

• 
  

• Environmental Adaptability: The operating temperature range is -40℃ to 70℃, which can operate normally in cold northern regions and high-temperature industrial environments; the relative humidity is 5%-95% (non-condensing), which can adapt to humid working scenarios such as ship engine rooms. It has good anti-vibration performance, can withstand vibrations with a frequency of 10-2000Hz and an acceleration of 10g, and the anti-impact performance reaches 30g, ensuring stable work under vibrations and impacts generated during equipment operation.

• Communication Interface: Equipped with an RS-485 communication interface, supporting the Modbus RTU protocol, which can realize communication with upper computers and monitoring systems, facilitating remote monitoring and data transmission. The communication rate can be adjusted in the range of 9600-115200bps to meet different communication needs.

• 
  

• Precise Parameter Control: WOODWARD 5466-425 adopts an advanced PID control algorithm, which can precisely control parameters such as engine speed and load. During equipment start-up, loading, unloading and other processes, it can quickly respond and adjust the control quantity to stabilize the parameters at the set value, improve the stability and efficiency of equipment operation, and reduce equipment loss caused by parameter fluctuations.

• Rich Protection Functions: It has a built-in perfect protection mechanism. When the engine has abnormal conditions such as overspeed, over-temperature, low oil pressure, and overload, the controller can quickly detect and issue an alarm signal, and take corresponding protection measures at the same time, such as reducing the load, stopping the machine, etc., to prevent the expansion of faults and protect the safety of the engine. In addition, it also has a fault memory function, which records information such as the time and type of the fault, providing convenience for fault troubleshooting.

• 
  

• Flexible Configuration and Programming: It provides special programming software, supports ladder diagram and function block diagram programming methods, which is convenient for users to write control programs according to actual needs. Through the software, the parameters of the controller can be flexibly configured, such as control thresholds, alarm settings, etc., so that the controller can adapt to different types of engines and specific application scenarios, and improve the adaptability of the system.

• Convenient Monitoring and Diagnosis: It has a real-time data monitoring function, through which the real-time speed, temperature, pressure, load and other parameters of the engine, as well as the operating status of the controller, can be viewed through the upper computer software. At the same time, the built-in diagnostic function can diagnose its own hardware and connected sensors and actuators, find potential faults in time, facilitate maintenance personnel to deal with them in advance, and reduce equipment downtime.

• 
  

• Good System Compatibility: It is compatible with various types of engine sensors, actuators and other control equipment, and can be easily integrated into different power control systems. Whether it is the construction of a new equipment control system or the control upgrade and transformation of old equipment, it can be quickly integrated, reducing the difficulty and cost of system integration.
