I have a sensor which is excited by a nominal 12V supply and outputs either supply voltage when closed or supply - 2 volts when open.
The input voltage can vary by +/- 3V.
I need to convert this to supply voltage when closed and 0 V when open to activate another circuit. What is the simplest method to achieve this.
