模拟量模块的作用

1、模拟量输入模块的主要作用是收集模拟信号。收集外部压力传感器后，在模块内部收集压力传感器收集的模拟信号，并进行相应的处理。这里的

传感器数据包括电压、电流、热阻、热电偶、温度等模拟值，然后通过总线传输给计算机的智能模块。

2、模拟量输出模块的作用是通过数模转换输入的数字信号进行转换，输出可控制的连续电流和信号。

3、数字量模块:数字量模块有输入输出两种功能。如果不采用这种方法集成，可以节省更多空间，否则用户在使用时需要买两个模块，数字量模块

解决了这一问题，即:集成输入/输出功能，一个模块既可以输入信号也可以输出信号。

The role of analog module

1. The main function of the analog input module is to collect analog signals. After collecting external pressure sensors, the analog signals collected by the pressure sensors are collected inside the module and processed accordingly. there

The sensor data includes analog values such as voltage, current, thermal resistance, thermocouple, temperature, etc., and is then transmitted to the intelligent module of the computer through a bus.

2. The function of the analog output module is to convert the input digital signal through digital to analog conversion, and output controllable continuous current and signal.

3. Digital module: The digital module has two functions: input and output. If this method of integration is not adopted, more space can be saved, otherwise users will need to buy two modules, the digital quantity module, when using it

Solved this problem by integrating input/output functions, where a module can both input and output signals.
