Abstract: A configurable multi-sensor analog input may be utilized to connect a power system sensor to an intelligent electronic device. The configurable multi-sensor analog input may include an input port comprising a plurality of input pins and configured to receive electrical signals from one of a plurality of types of power system sensors. The configurable multi-sensor analog input may additionally include a plurality of input channels, each of the plurality of input channels coupled to a subset of the input pins, wherein the subset of input pins in electrical communication with of the plurality of types of power system sensors power system sensor is configured to selectively activate one of the plurality of input channels. A multiplexer may be in electrical communication with the plurality of input channels and configured to select an output based on the subset of input pins in electrical communication with one of the plurality of types of power system sensors.
