handy LED indicator lights
For my purposes, I don't even use the 3.3V outputs. I just wanted a convenient set of indicator lights to monitor some 24V lines. They light up. Perfect for my testing!

it works, but why can't we get a schematic diagram?
So, if you put 24 V on the input of a channel (and you'll need to be able to supply about 14 mA, based on my measurement), you can get an isolated 3.3 V output, if you provide the 3.3 V power. The output is not capable of supplying much current however; I was seeing the voltage drop dramatically with even 2 mA output current.That being said, if you need this kind of functionality, this is a very well made module for not too much money. It appears to use common EL817 isolators, with an infrared LED and a phototransistor output. The drop across the transistor was about 0.2 V (with no current).
