2 Channel 12V Relay Module with Optocoupler by ADIY is an interface board and can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on. With digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs.

This module from ADIY is designed to be integrated with 2 relays that it is capable of controlling 2 relays. The relay shield uses a high-quality relay with a rated load of 10A/250VAC,10A/125VAC, and 10A/28VDC.
