Im looking for something that converts a 0-10v analog signal to a digital that activates a relay. The long story is, I have a ventilation controller that puts a 0-10v signal out, depending on temperature, humidity and a couple other factors. I've used up all the relays that it has and I can use an…

Or just a simple NPN transistor. 10V on the base (thru a current limit resistor), collector pulls the relay coil 'output' low to energize it.
