I have 415V , 200A 3 Phase wire system., Now i want to feed this inputs to a Controller which allows analog data of 0-20mA.
We can use control transformer (200A to 5A)+ Control transducer (5A to 0-20mA).

But these are costly as well as consuming lot of space.,
Is there any other way where i can get the desired outputs with minimal costs as well as space.

 

For your consideration ...
https://aimdynamics.com/product/333-mv-to-4-20-ma-transducer/
This device converts a millivolt AC signal to 4-20 ma. There is not anything shown that explains the 4 ma minimum value.
... It may be possible to shift the resulting output to a 0-16 ma range, if that is necessary.
... One additional component would be a toroid, or something similar, to link primary AC current flux to an AC millvolt signal.
... As you have pointed out, the project hinges on the economics.

 

One thread is enough, this thread will be closed.
