I want convert -10 _ 10 v to -10ma_10ma and -10 _ 10 v to 4_20 ma. I want convert -10ma _ 10ma to -10_10v. and 4_20ma to -10_ 10v.
Hi, If you prescale the +/-10V to 0-10V you can use this to get 4-20mAXTR110 (V-I) To make +/- 10v from 4-20mA(and +/-10mA), use a quality resistor to measure over and scale the voltage to +/- 10v. The 4-20mA scaling needs offset adjustment, but the +/- 10mA is straight forward. To be honest, conversion to +/- 10mA I have never seen. TOK
