Hi All,

Could some one help me with a circuit that converts 4mA - 20mA current to 0V - 5V volatge using opamp(741/LM324)?

Regards,
Ravi
 

yes. it is very simple. you should run this current from a resistor like 500 ohm. it produce a voltage between 2-10 volt and then design an opamp crcuit to change it from this voltage from 2-10 to 0-5v. simple right?
 

Look also at this thread, hope it help.



Cheers

raise a 250 ohm resistor at 250 ohm resistor at both ends can be removed from 1 to 5V voltage signal. The chemical instrument is now used all three types table, few 0 to 5V input signals, so you still use the bar from 1 to 5V.
