Will the CR3003 (24V DC PWM signal to 0-5V analog output module) work with a +12V supply and a +12V PWM signal? If not, is there another product you sell or are aware of that would convert 12V PWM into 0-5 analog?

Decided to give it a try (was using it on a 24V system already) and the CR3003 appears to function exactly the same on 12V as it does with 24V.

More detailed info on teh CR3003 and operation at different voltages.

Inside of the module there is the operational amplifier LM258.
The supply range for the operating voltage is 5 to 30 V DC. To
get out a 5 V signal you must have a operating voltage that is
~ 2.5 V higher. So the data for operating voltage is ~ 8...30 V DC.
