基本信息：5X00589G09 EMERSON 模拟输入模块

首先我们知道模拟是在一定范围内连续变化的任意的值，是与数字值相反的状态显示。而模拟量通常用于收集和显示物体的电压、电流或频率。

一、模拟量模块的种类

(1)模拟量输入模块

模拟量输入模块也称为A/D模块，它将从各种工业现场传感器中采集的模拟量信号转换成CPU可以识别接收的数字量。

(2)模拟量输出模块

模拟量输出模块又称为D/A模块，简单来说就是将模拟量输入模块CPU送来的数字量转换成其他外部设备1识别接收的电压或者电流等信息。

(3)数字量模块

数字量模块的主要作用就是检查外部开关输入的状态。数字量输入输出信号是开关量信号，1或者0。

二、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。

First of all, we know that the simulation is an arbitrary value that continuously changes within a certain range, which is a state display opposite to the digital value. Analog quantities are often used to collect and display the voltage, current, or frequency of an object.

First, the type of analog module

(1) Analog input module

The analog input module, also known as A/D module, converts analog signals collected from various industrial field sensors into digital quantities that the CPU can recognize as received.

(2) Analog output module

The analog output module is also called the D/A module, which is simply to convert the digital quantity sent by the analog input module CPU into other external devices 1 to identify the received voltage or current and other information.

(3) Digital module

The main function of the digital module is to check the status of the external switch input. The digital input/output signal is a switching signal, 1 or 0.

Second, the role of analog module

1. The main function of the analog input module is to collect analog signals. After collecting the external pressure sensor, the analog signal collected by the pressure sensor is collected inside the module and processed accordingly. Here the sensor data includes voltage, current, thermal resistance, thermocouple, temperature and other analog values, and then transmitted to the intelligent module of the computer through the bus.

2, the role of the analog output module is to convert the input digital signal through the digital-to-analog conversion, and the output can be controlled continuous current and signal.

3, digital module: digital module has two functions: input and output. If you do not use this method of integration, you can save more space, otherwise the user needs to buy two modules when using, the digital quantity module solves this problem, that is, integrate the input/output function, a module can both input signals and output signals.
