Power supply circuit: power supply circuit is a part of the circuit that provides energy to each unit circuit in the whole circuit board. It works in the environment of high voltage and high current, and is the most prone to failure.

The function of the power supply circuit is to convert 220VAC or 380VAC AC into various levels of DC with constant output voltage of ±5V, 12V, 15V, 18V and 24V required by the circuit board.

Input interface circuit: The input interface circuit is a part of the circuit for information exchange and communication between the circuit board and the outside world. It can convert what people want to say or do to the circuit board into electrical signals that can be recognized by the microprocessor in the circuit board. For example: When we are monitoring the temperature, if you say to the microprocessor in our common human communication language that the temperature is too high, please turn it down a little, the microprocessor will not understand what we say. At this time, we can convert the temperature signal into electrical signal by using thermistor or thermocouple components through the interface circuit, and then process the converted electrical signal. You get an electrical signal that the microprocessor recognizes. That way, when the microprocessor understands what we want it to do, it can do what we want it to do. The same is true for other signals such as illumination, pressure, wind, liquid level, position and so on.
