Summary

The Arduino 4 Relays Shield provides four independent relay channels with optical isolation for switching high-power AC/DC loads, designed specifically for Arduino compatibility.

Description

This official Arduino relay shield features four high-quality relays with optical isolation, each capable of switching loads up to 24VDC at 2A or 250VAC at 5A. The shield includes screw terminals for easy wiring, status LEDs for each relay, and full compatibility with Arduino boards. It's designed for home automation, industrial control systems, and any application requiring reliable switching of high-power circuits.
