1. Basic design of the cabinet
The design of the mechanical PLC cabinet with refrigeration adopts a compact and fine structure to ensure efficient space utilization and stable performance. High-quality materials and components are used inside the cabinet to enhance seismic resistance and prevent electromagnetic interference. The exterior of the cabinet adopts a modern design, which is easy to operate and maintain. The easy-opening design of the cabinet door makes it easy to view and replace the internal components.
2. Power configuration information
The PLC cabinet is equipped with a reliable power supply system, which supports 220V AC and DC24V DC power input. The power supply system has the functions of over-current, over-voltage and under-voltage protection to ensure the stable operation of the system. In addition, the power configuration includes a standby power switching function to provide continuous power in the event of a mains failure.
3. Refrigeration system description
The refrigeration system uses advanced circulating cold water technology to cool the heating elements in the PLC cabinet. The system can automatically adjust the number of refrigerators and the flow of cold water according to the temperature in the PLC cabinet to ensure that the temperature in the cabinet is always kept within the appropriate range. The refrigeration system also includes a temperature sensor and an alarm device that automatically alarms and takes corresponding cooling measures when the temperature exceeds the set range.
4. Environmental conditions
In order to ensure the normal operation of the PLC cabinet, its use environment needs to meet the following conditions:
Temperature range: 5°C~40°C
Relative humidity: 35%~85% (no condensation)
Atmospheric pressure: 1080~795hPa (equivalent to altitude -1000~2000m)
Special pollutants: SO2: <0.5ppm; H2S:<0.1ppm; Relative humidity: <60% (no condensation)
5. Protection level standard
The PLC cabinet is IP20 rated, which means it prevents the ingress of solid foreign objects larger than 12.5mm in diameter, prevents human fingers from touching the parts inside the appliance, and protects against other foreign objects of medium size (more than 12.5mm in diameter).
6. Main features
High programmability: The P LC cabinet supports complex control tasks and can be programmed to meet a wide range of application requirements via software programming.
Scalability: The system can be selected according to different system environments to meet specific application needs.
Efficient refrigeration: The advanced refrigeration system ensures that the temperature in the cabinet is always kept within the appropriate range, improving the reliability and stability of the system.
Ease of Maintenance: The cabinet is designed to be easy to open and close, making it easy to view and replace internal components.
High security: The system is equipped with a variety of protection functions, including over-current, over-voltage, under-voltage, and temperature alarms.
7. Maintenance points
Regularly check the operating status of the refrigeration system to ensure that the cooling effect is good.
Clean the interior and exterior of the cabinet from dust and dirt and keep the heat dissipation channels clear.
Check whether the power cord and connection cord are loose or damaged, and replace the damaged parts in time.
Regularly inspect the components and sensors inside the cabinet to ensure that they are working properly.
Regularly maintain and maintain the PLC cabinet to prolong the service life.
