Although the sheet says "volt free", I am measuring them at 5v.
Here's what we got. This module was meant to be an easy way for me to get a 0-10v output to control a piece of plant, this module gives a 0-10 or 0-9v output based on different combinations of the 4 inputs.
If I "close circuit" any of the 2 pins on the 4 inputs I change the output voltage, which is exactly what I want to do.I thought I could just connect an output pin on the Arduino and the other to ground on the Arduino and when program dictates, change the state of the output pin and this would be enough to close cirction the input on this module but this does not seem to be the case.
