This is the relay I needed and I bought 5 so now I have extras. It's an exceptionally good deal. The boards are very small and screw terminals on power, input and the relay contacts make it easy to connect and disconnect. Don't pay extra for tracking because the tracking isn't properly updated. Just be patient and expect the shipping to take at least 3 weeks.
Great item for the price of it. With a selectable jumper for High or Low
Good quality product, the packaging should only be safer, since everything came in a bag.
Отличные платы, очень качественные и очень удобные в использовании. Рекомендую. Подробно показал в видео: http://www.youtube.com/watch?v=OGvWFi5jfIA
