3.Excellent Heat Dissipation Effect

·Fanless cooling technology reduces energy consumption, eliminates noise, and prevents dust ingress, significantly lowering maintenance costs.

4.Unique Integrated Structure

·Highly integrated components such as the motherboard and display screen provide a user-friendly interface.

·Wide-voltage input design accommodates various unstable environments.

【Working Principle】

The computer mainly consists of an embedded computer, a 24-inch LCD screen, an intrinsically safe power supply board, an isolated circuit board, and an optical fiber transceiver.

For a computer, the two most critical components are the CPU and memory. The memory stores the program instructions to be executed, while the CPU executes these instructions. The CPU must first locate these instructions in the memory before executing them and writing the results back to the execution area.
