hi..
i'm really interested in that.
And i have checked the given ckt. that was really nice.but that is not suitable to use in an industry.
thnx
hi tnuflora,
Look at the attached pdf.
The design has been built and checked OK, using loop resistances of 330K thru 1M0 and a short circuit loop.
You will understand, as I will not be the person building and using this unit I will not be held responsible
for any damage or injury that may result from using this design.
EDIT: added 1M0 hysteresis resistor.
