Working principle

When an external device generates a digital signal (such as a high-level signal when a switch is closed), the signal is transmitted to the input terminal of the module through a connecting cable. The optoelectronic isolation devices inside the module first electrically isolate the input signal to prevent interference signals from entering the internal circuit. The isolated signal is subjected to signal conditioning circuits for amplification, shaping, and other processing to meet the input requirements of the internal digital circuit of the module. The processed signal is transmitted to the digital signal processing unit, which samples and encodes the signal, converts it into a digital quantity, and stores it in the input data register. When the control system issues a read instruction, the module transmits the digital signal in the register to the control system through the data bus, and the control system executes the corresponding control logic based on the received signal status.

For the output process, when the control system generates control instructions, the instructions are transmitted in digital signal form through the data bus to the output data register of the module. The signal in the output data register is also processed by the digital signal processing unit and transmitted to the output driver. The output driver amplifies the signal to meet the driving requirements of external loads. The amplified signal is isolated by a photoelectric isolation device and transmitted to the external execution device through the output terminal to control the device to perform the corresponding action. Throughout the entire working process, the state monitoring circuit continuously monitors the working status of the input/output channels and internal circuits of the module. Once any abnormalities are detected, the alarm mechanism is immediately triggered.
