Working Principle:
The module collects external digital signals through the input circuit, performs signal conditioning, filtering and analog-to-digital conversion, transmits processed data to the main control unit for logic operation. After executing control instructions, the drive circuit outputs digital control signals to external actuators. The built-in protection circuit monitors operating status in real time and triggers protection actions when abnormal electrical parameters occur.
