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 signals that can be recognized by the CPU.

(2) Analog output module

The analog output module is also known as the D/A module, which simply translates the digital quantity sent by the CPU of the analog input module into other external devices. 1 Identify the received voltage or current and other information.

(3) digital quantity module

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

Second, the role of the analog module

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

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

3. Digital module: digital module has two functions: input and output. If this method of integration is not adopted, more space can be saved, otherwise the user needs to buy two modules when using, digital quantity module solves this problem, namely: integrated input/output function, a module can both input signal and output signal.
