Does what it's supposed to do with style!
For Isolated Wide Voltage Range Interface Board, Qty 2
Excellent product. The seller kindly 'threw in' a few extra bits that I found useful. It was shipped promptly, showed up in perfect condition and was very high quality. I stuffed and soldered in the components I had and conducted a few tests. Everything worked perfectly. The product is now 'in service'! I highly recommend this seller and this product. I use it to interface my Raspberry Pi to the outside world. I am sensing 24VAC (that drives a standard garden irrigation valve) and have programmed my RPi to record valve actuation intervals in a file and display them locally on a 22 line LCD along with ambient temperature and humidity. This product creates a logic signal at 3.3VDC for the RPi from the 24VAC valve actuation signal. The 24VAC signal is optically isolated from the 3.3VDC logic signal so ground loops and other issues with grounds are completely eliminated. This product can deal with voltages that are other than 24VAC and 3.3VDC by adjusting various resistor values and pullup voltages. Very happy!!!!
