On that diagram, could I use a 1k and a 2k resistor instead of the 27 and the 13.3 ?

I would like to be able to be able to convert a 0-24v dc signal into a 0-10v dc signal This is to monitor the level of charge in some UPS batteries on site, my IQ3 can "see" between 0-10V DC but my batts will be between 0-24V DC Any Thoughts

Cheers DRWeig, refreshing to find a forum full of people willing to help and give good advice :)

I've found this little guy http://cpc.farnell.com/unbranded/vhlr/very-handy-little-relay/dp/HK00259 Switches from 1-10V and the coil draws 18ma It can switch 230V, so will basically convert my analogue output into a digital one.

Ah, thanks guys. Any way I can make this fire a relay? I guess one with a 10V coil?

There is only the one IQ3 in this project. I'm measuring between 35 and 36, shows an open circuit, then 12V DC when the LED comes on (when the relay output is supposed to be closed)

Hi folks, I'm new here, first post. I'm installing a Trend IQ3, and have set it to close two of the relay outputs based on a time clock (simple stuff I know). However, this doesn't seem to actually close the relay output? 'SET' thinks its shut, the IQ3 thinks its shut and the LED comes on, but...
