Abstract
A method and input circuit unit having a first input circuit and a redundant second input circuit, wherein each input circuit includes an input for feeding a measurement current that can be obtained from a signaling device and that can be switched over and operated in such an input circuit unit, where the measurement current causes a voltage drop across a measurement resistor that can be evaluated as a measured value, where a parallel connection of the first and second input circuits causes division of the measurement current among the first and second input circuits, and where at least one input circuit include a device for compensating the decreased voltage drop across the measurement resistor resulting from the division of the measurement current.
