Relay Shield 4 Channels 6-12V For Uno RobotDYN

The 4-channel Relay Shield is designed for safely controlling high voltage and high power devices using a microcontroller. It is suitable for switching 220V AC appliances, motors, pumps, and other power equipment while keeping the control circuitry isolated and protected. This shield features four high-power relays with optocoupler isolation, ensuring that the Arduino or microcontroller is electrically separated from the load side. The layout places relays and terminals outside the Arduino area for easier wiring and improved safety.
