Be aware that the relay needs 24 volts DC connected to the orange terminal. you can then use a 5v signal from an arduino to change the state of the relay. many of the these brands have different supply voltages other than 24 volts so be sure to read carefully. ### ⭐⭐⭐⭐ 4.0 out of 5 stars producto de muy buena calidad *by F***A on Reviewed in the United States on August 9, 2018* Muy funcional y practico ### ⭐ 1.0 out of 5 stars no instructions *by I***Y on Reviewed in the United States on July 4, 2018* The device does not come with any instructions on how to wire it. I've tried a couple of ways but it won't work. Seller ask that you don't leave negative feedback without asking them first, but there is no Ask the seller button for them so I don't know how to contact them.
