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

The Arduino 4 Relay Shield is a solution for conducting high power loads that cannot be controlled by Arduino digital iOS, due to the current and voltage limits of the controller. The Shield has four relays, each relay provides 2 pole switching contacts (NO and NC); in order to increase the current limit of each output, the 2 switching contacts have been put in parallel. Four LEDs indicate the on/off status of each relay.

• 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.
