Hi All
I'm pretty new to electronics. I'm building a circuit where I need to sense a DC signal between 9 and 24v DC and an output to a microcontroller. I want to use a PS2501-4 (http://www.cel.com/pdf/datasheets/ps2501.pdf), but I'm kind of stuck on figuring out the range of input voltages it supports and what I should use to ensure this range of voltages will trigger it.
I looked at the data sheet, but can't for the life of me figure out what the max input voltage is.
In addition to this, I then need to figure out how to generate enough forward (for the 9-24v input) to trigger the device. I'd like to keep the no of components to a minimum due to size limitations.
Any help/explanations would be appreciated
Thanks
Mark
