The present disclosure relates to an adaptive logic board that includes a signal sensing circuit configured to receive an input signal as an electrical current. The signal sensing circuit includes a plurality of resistors and a plurality of switches configured to electrically couple or electrically decouple the plurality of resistors from the signal sensing circuit, in which each switch of the plurality of switches corresponds to a corresponding resistor of the plurality of resistors. The adaptive logic board also includes a sensing unit that is configured to measure a voltage drop of the input signal across an active resistor of the plurality of resistors.
