Abstract
An input device includes an input line connected to a voltage divider node for connecting a load to the voltage divider node. A first switching component connects to the voltage divider node. A first resistor connects to the voltage divider node for connecting a first voltage source to the input line. A second resistor connects between the input line and the voltage divider node for limiting current to the load, wherein the first voltage source is also connected to the first switching component. A second switching component is operatively connected to the first switching component, wherein the second switching component is configured to connect an second voltage source to a logic device for discrete input to the logic device that is decoupled from voltage supplied to the input line by the first voltage source for providing logic high and low input regardless of voltage supplied by the first voltage source.
