Eric,
What is the difference between the 5V1 and 5V6 Zener?
Would adding a 10K to the wiper add versatility to this overall design?
When Eric posted this latest circuit, it was intended to supply a 12V signal to a Electric Switch. My circuit was also designed so the Switch was activated up until the Vsrc reached a desired voltage. (set by vset). Unless I am mistaken, this circuit can be universal. If I switched the the relay to the N/O configuration, I am understanding that the operation would be the opposite. In other words, the "switch" will be deactivated, and activated when the Vsrc reached the same set Vset. Just a matter of how you used the SPDT pin outputs. Eric could correct me though. ALso, this same circuit could be used as a regular "on-off" switch, by disconnected my 12v to the center pin of the relay, and use the N/C and N/O pins as a "turn-on" or "turn-off" switching.
My circuit works great without the 10K resistor into pin 3. I have made voltage checks, and I am getting the desired levels on the Vset.
I will eventually use this same circuit as just a "on"-"off" switch for another application. I have already completed the PCB123 layout, just havent done the pricing thing yet.
I also plan on giving a few away to other freinds when all said and done. Might send Eric a donation for his help.
