GCD207B1013BHEO24642RO101 In circuit boards, regardless of the type, they are basically composed of seven major circuits: power supply circuit, input interface circuit, microprocessor control circuit, output interface circuit, display circuit, protection circuit, and communication circuit. As long as we master the composition structure and control principles of these seven major types of circuits, know the structural characteristics and key components of each type of circuit, can determine which type of circuit each part belongs to in the circuit board, be familiar with the fault patterns and characteristics of each type of circuit, and can carry out maintenance for various types of circuit boards. GCD20781013BHEO24642R0101 power supply circuit; The power supply circuit is a part of the circuit that provides energy to each unit circuit in the entire circuit board. It operates in high voltage and high current environments and is the most prone part of the circuit to malfunction.

GCD207B1013BHEO24642RO101 input interface circuit: The input interface circuit is a part of the circuit board that exchanges information and communicates with the outside world. It can convert what one wants to say or do to the circuit board into electrical signals that the microprocessor in the circuit board can recognize. For example, when monitoring the temperature, if you use the language we usually use to communicate with people to listen to the microprocessor. If the temperature is high, please turn it down. The microprocessor cannot understand what we are saying. In this case, you can first use a thermistor or thermocouple element to convert the temperature signal into an electrical signal through the interface circuit, and then process the converted electrical signal to obtain an electrical signal that the microprocessor can recognize.
