Computer Controlled 100ma Current
Source (July 11, 2008) |
| 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. |
