Computer Controlled 100ma
Current Source (July 11, 2008)
designed by David A. Johnson, P.E. |
| Often in industrial
control systems a constant current source is needed, which is controlled by a
computer and referenced to circuit ground. This hobby circuit below converts a
zero to 5v signal from a computer’s analog output into a current, with a full
scale of 100ma. This hobby circuit shown requires a 9v DC supply but any voltage
from 9v to 12v will work. |
