I found this circuit on here I added some changes. One a 120 ohm 1 watt resistor to insure that the 2n7000 doesn't see more then 200 mA maybe over kill but. The V+ will be 24 volts or less
The 1 ohm 1/2 watt will be read by the pic's ADC to set the output to 4 to 20 mA
Would this work **broken link removed**
The read resistor will be read with a Pic down the line
Thanks Burt
