1-channel opto-isolated relay module uses optical coupling to isolate the control side from the load side, effectively suppressing voltage spike interference and protecting your main control board. You can choose high-level or low-level trigger according to your program design. The red indicator lights up when the relay is activated. It can switch small AC and DC loads. It is widely used for smart home automation, equipment power control, fan and light switching, solenoid valve driving and various electronic DIY automation projects. Two modules are included for multi-channel control or backup use.
