data acquisition from current transformer
data acquisition from current transformer
(OP)
Hello everyone, I am beginner in data acquistion, is there anyone can help me to build a low cost low speed 16 channel 8 bit A/D converter, the input signal is from panel curent transformer ( 20/5 A, 50/5 A, etc ). I only need 1 conversion per secon for each channel, with the precision of +/- 0.5 A. The data will be captured by pc, the distance between pc and signal source (input signal cable) about 50 m.
thank you
thank you

If this is for a single application, that would be a very expensive excersise. There are many other roads to choose from. Like LabView, a PLC with analogue front end, the little LabJack U12 and many more. I would have a deep look at the LabJack. It has eight channels and you can connect two to one PC, easily. Cost is next to nothing. I have used it for multi-channel acquisition at 50 readings/second. No sweat. Resolution is a lot better than you need. I think that is not a problem
Google "LabJack U12"
