  • Patent number: 9423784
    Abstract: A sensor arrangement for detecting a safe installation state of an automated installation has an input circuit designed to receive a first input signal and at least one further input signal. The first input signal depends on the safe installation state to be detected. The further input signal depends on a further operational state. The sensor arrangement also has a first output and at least one second output and an evaluation unit for outputting a first output signal and a second output signal at the first and second outputs, respectively. The evaluation unit is designed to evaluate the first input signal in a failsafe manner and on the basis thereof produce a redundant signal pair at the first and second outputs to signal a safe installation state, and to evaluate the further input signal and on the basis thereof generate non-redundant output signals different from the redundant signal pair.
