Hello all! This is my first post. Thanks in advance for any help. I'm pretty new to electronics but work as a software programmer, so hopefully my technical mind will help me out on this little project
My goal is to take a 10V/32ma signal from a lighting control system to flip a SPDT relay to turn on a 24v peristaltic liquid pump. I was hoping I could do this with a standard 12v automotive relay switch, but either the voltage or current wasn't high enough to flip the relay, or I'm doing something else wrong.
Here is the relay I got. Unfortunately I can't find specs for it on the minimum switching voltage or current. I know 15 volts works from testing, but putting three batteries of 9v, 1.5v and 1.5v in series doesn't trigger the relay, which I find very confusing. Maybe those batteries aren't generating enough current to energize the coil? Maybe I need a low current relay? But those seem to be digital whereas this is an analog application.
In short, what is the simplest approach for a novice to turn on a 24v pump with a 10V/32ma analog signal?
