Arduino 4 Relays Shield [A000110] - 4-Channel Relay Module, 5V Control, 10A Rating, Opto-Isolated, Supports AC/DC Loads, Compatible with Arduino IDE for Automation and Control Projects

4-Channel Relay Control: The Arduino 4 Relays Shield allows you to control up to 4 independent relays, enabling you to switch high-voltage devices (AC or DC) with your Arduino for home automation, robotics, and control applications. 5V Control Voltage: Designed to operate at a 5V control voltage, this shield is perfect for direct integration with Arduino boards like the Uno, Mega, or Leonardo, ensuring seamless communication and control. High Current Switching: Each relay is rated for 10A at 250V AC or 30V DC, providing ample power for controlling a wide range of devices, including lights, motors, pumps, and other high-power equipment. Opto-Isolated for Safety: The relays are opto-isolated to protect your Arduino board and other sensitive electronics from voltage spikes and electrical noise when switching high-power loads. Fully Compatible with Arduino IDE: Easily integrate the shield with your Arduino projects using the Arduino IDE, with available libraries and examples to get your relay-controlled systems up and running quickly.
