I have a sensor that measures 2000 ohms in 1st position, 1400 ohms in second position. I would like to build a 12 volt D.C. circuit to control a relay.
12 volt power to relay coils in 2000 ohm position, relay contacts close,
Power to relay coils drop out, relay contacts open in 1400 ohm position.
The relay I an using has 220 ohms across the coil.
Any ideas appreciated.
Thanks
