Perfectly fine. This models seams to not have the overvoltage of the relay because it accepts only 5v and not 12v with a regulator like other brands. The 5v alimentation is provided by the pins or by the blue cable older. Good product, I recommend
Module arrived before scheduled.
Thank you very much.
conforms to the ad send quick I recommend
Perfect relay. It really works very well. I've tried and have wired three of the four relays and they work. recommended if you need three or more relays.
Tested and works perfectly.
