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.
