WOODWARD 5453-277 TMR Power Supply Chassis

WOODWARD 5453-277 is a high-performance controller specially designed for small and medium-sized engine control, and is widely used in the control systems of clean energy power equipment such as natural gas engines and biogas engines.

• 
  

• Power Supply Parameters: It adopts 12V DC or 24V DC power supply, with operating voltage ranges of 9-16V DC and 18-32V DC respectively. The power supply mode can be flexibly selected according to different application scenarios, adapting to fluctuations in the power supply voltage in industrial sites and ensuring the stable operation of the controller. The power consumption is low, with a rated power consumption of about 8W, 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 3 analog input channels, which can receive 4-20mA or 0-5V 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 6 digital input channels and 4 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 ±0.3% of the rated speed, which can well 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 ±2%, which can meet the load adjustment needs of small and medium-sized engines and adapt to different load changes.

• 
  

• Environmental Adaptability: The operating temperature range is -30℃ to 65℃, enabling it to operate normally in a relatively wide temperature range; the relative humidity is 10%-90% (non-condensing), which can adapt to working scenarios with a certain humidity. It has good anti-vibration performance, can withstand vibrations with a frequency of 10-1000Hz and an acceleration of 5g, and the anti-impact performance reaches 20g, ensuring stable work under vibrations and impacts generated during equipment operation.

• Communication Interface: Equipped with an RS-232 communication interface, supporting the Modbus 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 2400-9600bps to meet basic communication needs.

• 
  

• Precise Parameter Adjustment: WOODWARD 5453-277 adopts a mature PID control algorithm, which can precisely adjust 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.

• 
  

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

• Simple Configuration and Operation: It provides an intuitive operation interface and special configuration software. Users can set the parameters of the controller through the software, such as control thresholds and alarm settings. The operation is simple and convenient, without the need for complex programming knowledge, enabling the controller to quickly adapt to different models of small and medium-sized engines and specific application scenarios, and improving the adaptability of the system.

• 
  

• Convenient Status Monitoring: It has basic real-time data monitoring functions. Through the upper computer software, users can view key parameters such as the real-time speed, temperature, and pressure of the engine, as well as the operating status of the controller. At the same time, it has a built-in simple diagnostic function, which can diagnose its own basic hardware and connected key sensors, find potential faults in time, facilitate maintenance personnel to deal with them in advance, and reduce equipment downtime.

• Good Economy: Designed for the control needs of small and medium-sized engines, it has a relatively low cost on the premise of meeting basic control functions, and at the same time has low power consumption, which can reduce the operating cost of the entire system. Its compact structure design is also convenient for installation on equipment with limited space, improving the flexibility of installation.
