Analog input module is a device used to collect and process analog signals, which is usually composed of analog input circuit, analog-to-digital converter (ADC), filter and interface circuit. The analog input circuit is responsible for converting the external analog signal into a voltage or current signal, and then converting the analog signal into a digital signal through an analog-to-digital converter, and finally filtering and enhancing the signal through a filter, and finally output to a computer or other control equipment for processing and analysis The working principle of analog input module 1. Analog input circuit: The analog input circuit is a key part of the analog input module, which is mainly responsible for converting the external analog signal into a voltage or current signal. Common analog input circuits include resistance divider circuit, current voltage circuit and so on. The resistance divider circuit realizes the signal conversion through the series parallel combination of resistors, and the current voltage circuit realizes the signal conversion through the product of current and resistance. 2. Analog-to-digital converter (ADC) : The analog-to-digital converter is the core component in the analog input module, which is responsible for converting analog signals to digital signals. The analog-to-digital converter discretizes the input voltage or current into a series of digital values according to its magnitude, and converts the continuous analog signal into a discrete digital signal through a process of sampling and quantization. Common analog-to-digital converters include successive approximation analog-to-digital converters and integral analog-to-digital converters. 3. Filter: The filter is an important part of the analog input module, which is mainly used to filter and enhance the signal. The filter can improve the quality and stability of the signal by removing high-frequency noise and interference signals, thus improving the accuracy and reliability of subsequent processing. 4. Interface circuit: The interface circuit is the connection bridge between the analog input module and the computer or other control equipment, which is responsible for converting the digital signal into a form that the computer or other control equipment can recognize and process. Interface circuit usually adopts serial communication interface or parallel communication interface, and realizes data exchange and communication with computer or other control equipment through data line and control line.
