The RS485 bus receiving module and the RS485 transceiver module work together to ensure the reliability and stability of communication.

[0133] Circuit protection: Resistors R20 and R21 in the main control module form a voltage divider circuit for monitoring the +3.3V power supply voltage. When the power supply voltage is abnormal, the main control chip U2 can detect the voltage change through pin 31 and perform corresponding protection measures, such as alarming or shutting down the output. Transistor V14 and resistor R29 form a simple overcurrent protection circuit. When the output current is too large, transistor V14 is turned on to limit the output current and protect the circuit from damage.
