Your cart is empty.The Arduino 4 Relay Shield is a solution for conducting high power loads that cannot be controlled by Arduino digital iOS, due to the current and voltage limits of the controller. The Shield has four relays, each relay provides 2 pole switching contacts (NO and NC); in order to increase the current limit of each output, the 2 switching contacts have been put in parallel. Four LEDs indicate the on/off status of each relay.

I used this relay board to control an RO system based on water tank levels and it works perfectly. The relays provide both normally-closed and normally-open pins. I am using two of the relays to trigger the RO on and off, and the remaining to control status lights.Quality is as expected for a Genuine product. It fits nicely on the Pi and stays put.

La consegna è arrivata nei tempi previsti, ma il pacco è danneggiato e davvero maltenuto: senza alcuna imbottitura o scatolina esterna. Non mi stupirebbe se il prodotto non funzionasse del tutto. L'articolo è completamente coperto di polvere e all'apprenza sembra usato
