The multi-function relay control module is designed for various applications. It features a microcontroller as the main control unit and offers 32 preset functions, allowing users to select the appropriate function based on their needs. It can be used for water pump control, motor control, LED strip control, solenoid valve control, and more. The upgraded module provides 32 functions to meet a wider range of application requirements. Built-in power supply reverse polarity protection prevents damage from incorrect power connection. Timing accuracy reaches 0.01 seconds, with timing range from 0.1 seconds to 999 minutes. Low power consumption mode allows the display to be turned off to save energy.
