1 channel 5V DC Relay Module with Optocoupler

This single-channel relay module is an essential interface for safely switching high-current AC or DC loads using low-voltage microcontrollers like Arduino, Raspberry Pi, or AVR. It features Optocoupler Isolation, which electronically separates the sensitive control circuitry from the high-power load circuitry. This isolation is critical for preventing electrical noise and voltage spikes from damaging your microcontroller. The module is equipped with a high-current relay capable of switching up to 10A at 250V AC.
