I bought this thinking I could use a 5v or 12v signal on 85 and 86 to close the circuit on the 48v power source on 30 and 87 but the relay wouldn't click over until I tested it at 52v on 85 and 86.This is not useful for my use since it requires the same voltage level as what I'm trying to enable to begin with.
Thank you for your feedback
