AJMRTC Single Channel 3V Relay Isolated Drive Control Module adopts optocoupler isolation design to effectively isolate the control signal side and load side, protecting your main control board from surge interference. This relay board uses 3V power supply and supports high-level trigger control. When the input signal reaches the trigger threshold, the relay will pull in to switch the external load circuit. It can be directly driven by common microcontroller IO ports such as Arduino and ESP32. Compact PCB layout saves space for prototype design. It is widely used for intelligent power switching, small equipment control, automation experiments and other electronic DIY projects. The optocoupler isolation greatly improves system stability and safety.
