4-channel module 12V 10A relay controlled by 0V low state for Arduino

The 4-channel 12V 10A relay module is the ideal solution for controlling high-power devices with a microcontroller such as an Arduino. Using opto-isolation, the module protects the control circuit from interference, ensuring stable and reliable operation. Each of the four relays is triggered by a low state and can operate devices with a maximum voltage of up to 250V and a current of up to 10A. The module has built-in LEDs to indicate the status of the relays for easy diagnostics during operation. Specifications:
