Working principle

After the sensors on the industrial site generate analog signals, the analog input channel of the NAIO-03F analog I/O kit collects the signals, processes them through the signal conditioning circuit, converts the analog signals into digital signals through an A/D converter, and temporarily stores them in the internal memory. The control system sends instructions to the kit through a communication interface, reads stored digital signals, analyzes and processes them, and sends the control instructions back to the kit in the form of digital signals. After the analog output channel of the kit receives a digital signal, it is converted into an analog signal through a D/A converter, and then processed appropriately through a signal conditioning circuit. Finally, it is output to the actuator to achieve control of industrial equipment, thus completing the entire process of analog signal acquisition, processing, and control.
