What is it?

Isolated wide voltage range interface board that allows Raspberry Pis, Arduinos or any digital input to monitor a wide range of AC/DC voltages (12V, 24V, 48V, or higher). It has a built-in LED to make it easy to see when a signal is active. Can also be used as an R-R voltage divider or R-R-C voltage divider with low pass filter.

Each order contains 2 bare circuit boards. What components are populated, and the values used are dependent on the application. Once we get an idea of the interest in this design and the most common applications, we may be able to offer kits with often used component values.

Why did you make it?

I use Raspberry Pis and Arduinos to monitor and control systems in agriculture and industry and wanted a versatile interface board that could be used in a wide variety of prototype and low volume situations.

What makes it special?

It can be populated in a number of different ways to accommodate a wide range of AC/DC voltages (12V, 24V, 48V, or higher) with and without optical isolation, with two mounting holes and screw cage connectors to provide a stable platform for interfacing external signals. A Zener diode provides surge clamping/regulation and a filter capacitor filters AC signals or can hold the voltage steady for A/D converters.

Does what it's supposed to do with style!

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!!!!
