24 vdc data logger

[robh 12]

Having trouble finding what I need. I have a Keyence sensor that has a 24 vdc output. I need a data logger/state recorder that can record and time stamp each time the output is energized. It would be wonderful if the data logger/state recorder had 4 inputs. Even more wonderful if I could unplug data logger/state recorder and plug it in to my laptop to pull out the data. This is for a portable tattle tale unit measuring level in a sight glass. I have looked at Dickson and Omega but couldn't find what I think I need. Any ideas? Oh yeah, the cheaper the better. Thanks, Rob Edited 4 Nov 2010 by robh

Cool thanks! I will look into them.

That's a nice product line. I can see lots of uses for it as far as temporary troubleshooting, thanks for the link
