Cold dryer main control board

This universal controller uses Japan's Renesas high-performance 16-bit MCU as a logic control unit, and uses fuzzy control algorithm theory to intelligently and precisely control various inputs and outputs according to system requirements. The controller is equipped with multi-channel electronic expansion valve, pressure sensor, frequency conversion speed control water pump, output control of multi-channel switch value, and input control of multi-channel analog signals. This main board can be equipped with 4G Internet of Things module, which can perform parameter query, parameter setting, program upgrade and other functions on the unit through background operation.
