Convert 0-10 V to 4-20 mA using a resitor


It is extremely simple to measure 0-10 V analog signal from a sensor with a ACE PLC that will measure only current inputs.

If ACE current input accept a 0-20 mA signal, but may not accept a 0-10 V signal directly.

Basically, Ohms law is used to calculate a resistor value in order to convert the 0-10 V signal to a current.

0-10 VDC to 0-20 mA : 500 Ohms resitor

0-5 VDC to 0-20 mA : 250 Ohms resitor
