参数: NRD1 080348RDB44674G01 SA44674.C ALSTOM接口板模块

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。

电源供应电路的功用是:将220VAC或380VAC交流电转换成电路板所需的各种不同等级、输出电压恒定的+5V、12V、 15V、 18V、 24V等级别的

直流电。

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，它可以将人们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:我们在监控温度高低时，你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,我们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。这样的话微处理器明白了我们要它处理的事项后，他就可以按照我们的意图去做了。其它的像光照度、压

力、风力、液位、位置、等信号都是同样道理。

输入接口电路的功能是:将人们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平信号。

微处理器控制电路:微处理器控制电路主要用在主控制板电路板中，当我们看到电路板中模样长得四四方方或长方形形状、有很多引脚的元件,在它

的旁边有晶振元件的，这个元件大多是微处理器元件，以微处理器为核心元件的周围就是微控制器电路。

微处理器控制电路主要功能是:接受输入接口电路发送过来的相关信息，并对这些信息进行分析、处理,并作出相应的处理结果，把处理结果进一步

送给输出接口电路。

ALSTOM NRD108034 8RDB44674G01 SA44674.C Interface board module

Parameter: NRD1 080348RDB44674G01 SA44674.C ALSTOM Interface board module

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

Part of the circuit.

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

Direct current.

Input interface circuit: The input interface circuit is a part of the circuit board and the outside world for information exchange and communication, which can convert what people want to say or do to the board into the circuit board

Electrical signals that the processor can recognize. For example: when we are monitoring the temperature, if you use our ordinary human communication language to say to the microprocessor, the temperature is high, please turn it down - some, slightly

The reason is not to understand what we say, at this time, we can first use the interface circuit to convert the temperature signal into an electrical signal with a thermistor or thermocouple element, and then process the converted electrical signal

You get an electrical signal that the microprocessor can recognize. That way, once the microprocessor understands what we want it to do, it can do what we want it to do. Other things like illuminance, pressure

The same is true of force, wind, liquid level, position, and other signals.

The function of the input interface circuit is to convert what people want to say or do to the board into a level signal that the microprocessor in the board can recognize.

Microprocessor control circuit: microprocessor control circuit is mainly used in the main control board circuit board, when we see the appearance of the board in the shape of a square or rectangular shape, there are many pins in it

Next to the crystal oscillator component, most of this component is a microprocessor component, and the microcontroller circuit is surrounded by the microprocessor as the core component.

The main function of the microprocessor control circuit is to accept the relevant information sent by the input interface circuit, and analyze and process the information, and make the corresponding processing results, and further the processing results

Send to output interface circuit.
