Dear Gentlemen
Thank you for your answer but I have more questions. This are the information that I got from the vendor:
Operating voltage: | AC / DC 8 ~ 12V | ||
Measuring rate: | ≥2 times / S | Measuring rang: | AC 0~ 20A |
Over-range display: | the first shows "1" or "-1" | Operating current: | <15mA |
Based on the above info this is what I found:

My main consideration is the MA what I need for this project. Example do I need 4 or 8 these unit for a Postwar ZW, one each for the voltage and one for each Amp meter? Or can I bus bar one unit for all of the voltage and AMP units? Or am I dreaming and each voltage and AMP unit need it's own isolation unit?
