Often in industrial control systems a constant current source is needed, which is controlled by a computer and referenced to circuit ground. The circuit below converts a zero to 5v signal from a computer?s analog output into a current, with a full scale of 100ma. The circuit shown requires a 9v DC supply but any voltage from 9v to 12v will work. Source: discovercircuits
