### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great for projects
  

*by G***W on Reviewed in the United States on July 10, 2018*

Great for projects. 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.

    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. I hope this comment will help with that
