 		 #15076 - RE: How to convert 4-20 mA. to 0-5 V.
Reynaldo, of course 250 Ohms will generate 5 volts @ 20mA, that is not the issue. However, the 4-20 "standard" does not specify the voltage available from the current generator. A method often used is to put a remote meter (loop powered = high resistance), a local meter (same for uniform look) and a PLC in series in a current loop. In such a case you may tilt the apple cart by using 250 ohms.

Have fun
