模拟量信号，有2种，电压或者电流信号 ，一般是变送器传过来的信号，比如用压力变送器检测水管压力，它会输出一个模拟信号4–20ma 或者 0-10V的信号给PLC，PLC来进行数据处理。

开关量输入点(DI),处理开关量输入信号.

模拟量输入点(AI),处理模拟量输入信号(0-20mADC,0-5VDC).

电阻信号(含热电阻)输入点,处理热电阻或一般电阻信号.

高速脉冲输入点,处理高速脉冲信号.

电压(含热电偶)输入点,处理电压输入或热电偶信号.

还有通讯,用于和上位机交换数据或控制下级控制器仪表驱动器等

1.2数字量/模拟量输入模块区别

根据现场输入信号的不同，可将输入模块分为开关量输入模块和模拟量输入模块。

Analog signal, there are two kinds, voltage or current signal, is generally the signal transmitted by the transmitter, such as the pressure transmitter to detect the water pipe pressure, it will output an analog signal 4-20mA or 0-10V signal to the PLC, PLC for data processing.

The switching input point (DI) processes the switching input signal.

Analog input point (AI), processing analog input signals (0-20mADC,0-5VDC).

Resistance signal (including thermal resistance) input point, processing thermal resistance or general resistance signal.

High-speed pulse input point, processing high-speed pulse signal.

Voltage (including thermocouple) input point, processing voltage input or thermocouple signal.

There is also communication, which is used to exchange data with the upper computer or control the instrument driver of the lower controller

1.2 Difference between digital and analog input modules

According to the difference of field input signal, the input module can be divided into switching input module and analog input module.
