I'm not sure of the best subforum to post this...
We are looking for a comparator, preferably DIN-rail mountable, that will turn on a digital output when a 0-10V analog signal reaches a certain configurable threshold. The goal is to turn a linear potentiometer into a switch so that we can interface to a digital input in order to save money, since digital inputs are much cheaper than analog inputs.
I have not found much at all, partly because I'm not sure what search terms to use.
I've found a few options from Phoenix Contact that are almost cheap enough, and have seen some fancier options from other manufacturers but these are much too expensive.
