This relay board features two opto-isolated channels, allowing safe and reliable control of high-power devices. Operating at 5V, it uses transistors to drive the relays and optocouplers for output isolation, ensuring protection for your microcontroller. Each channel can switch loads up to DC 30V or AC 250V, making it suitable for controlling appliances and other equipment. The module includes 3-pin terminal outputs for each relay (NO, COM, NC) and can be directly interfaced with Arduino or other microcontrollers.
