ABB GCD207B101 电路板模块
GCD207B1013BHEO24642RO101在电路板中，不管是什么类型的电路板基本上都是由:电源给应电路、输入接口电路、微处理器控制电路、输出接口电路、显示电路、保护电路和通信电路等7大部分电路组成。只要咱们掌握了这七大类的电路组成结构和控制原理，知道每类电路的结构组成特点和关键部件，能在电路板中判断出每部分电路是属于那一类电路，熟悉每一类电路的故障规律和特点、就可以针对各种类型的电路板进行维修了。GCD20781013BHEO24642R0101电源供应电路;电源供应电路部分电路是向整个电路板中各个单元电路提供能量的一部分电路，它工作在高电压、大电流的环境下，是最容易出故障的一部分电路。
GCD207B1013BHEO24642RO101输入接口电路:输入接口电路是电路板和外界进行信息交换和沟通的一部分电路，它可以将想要对电路板所说的话或要办的事转化成电路板中微处理器能够识别的电信号。例如:在监控温度高低时，如果用咱们平常人与人交流的语言说给微处理器听，温度高了，请把它调低一些，微处理是听不懂咱们说的话的，这时，可以通过接口电路先用热敏电阻或热电偶元件将温度信号转成电信号，然后在对所转换出电信号进行处理，就可以得到微处理器可以识别的电信号了。
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.
