6. Real – World Examples
Manufacturing Plant In a food manufacturing plant, the PPC322BE was installed as an HMI for a filling machine. Operators used the touch – screen to set the filling volume and speed. During production, the display showed real – time data such as the number of filled bottles and the remaining raw material level. One day, a sensor detected a blockage in the filling nozzle. The PPC322BE immediately displayed an alarm message on the screen, and operators could quickly stop the machine and resolve the issue, minimizing production downtime.
Commercial Building In a large office building, the PPC322BE was used for the building management system. It was installed in the control room, where operators could monitor and control the HVAC and lighting systems. When the temperature in a particular floor exceeded the set limit, the PPC322BE sent a signal to adjust the air – conditioning system, ensuring a comfortable working environment for the employees.
In manufacturing plants, the PPC322BE can be used as a human – machine interface (HMI) for controlling and monitoring production processes. Operators can use the touch – screen display to set parameters, start and stop machines, and view real – time production data. For example, in a packaging line, it can control the speed of the conveyor belt, the filling amount of products, and monitor the status of sensors.
In machine tooling, it can display the operating status of the machine, such as spindle speed, feed rate, and tool position. Operators can also use it to program and adjust machining parameters.
Building Automation In commercial buildings, the PPC322BE can be used for building management systems. It can display and control the HVAC system, lighting system, and access control system. For instance, it can show the temperature and humidity in different areas of the building and allow users to adjust the settings accordingly.
Transportation In vehicles such as buses and trains, it can be used as a control panel for displaying information like vehicle speed, route information, and passenger announcements. It can also be used to control on – board equipment such as air – conditioning and lighting.
3. Weight and Dimensions
Weight The PPC322BE weighs approximately 1.5 kg, which is relatively light and easy to install and handle.
Dimensions It has dimensions of approximately 200mm (length) x 150mm (width) x 40mm (height). The compact size makes it suitable for installation in various industrial control cabinets and limited – space environments.
