  • Patent number: 10804927
    Abstract: A signal transmission device for pulse density modulated signals comprises a signal input for an input signal with a defined maximum signal value, a modulation stage for generating a pulse density modulated transmission signal out of the input signal, a locking device at the input for the pulse density modulated transmission signal to overwrite same with a static fault signal, a pulse reconstructing transmission path for the pulse density modulated transmission signal, a demodulation stage at the output, for reconstructing the input signal out of the transmitted pulse density modulated transmission signal, and a signal change monitoring device capturing the pulse density modulated transmission signal of the transmission path at the output, which has an error signal output for signaling the detection of a missing dynamic pulse density modulated transmission signal on the transmission path due to the static fault signal.

  • Patent number: 10771026
    Abstract: An isolation amplifier includes an input circuit at high voltage potential with an input for a measurement signal to be transmitted, an input circuit configuration providing a coupling section signal representing the measurement signal, and a high-voltage-side control unit for driving the input circuit, a galvanically isolating coupling section for the potential-free transmission of the coupling section signal to an output circuit at low-voltage potential with an output circuit configuration for generating an output signal from the transmitted coupling section signal, an output for the output signal and at least one low-voltage-side control unit for generating control signals, input elements for inputting control commands and/or parameters into the high-voltage-side control unit, a low-voltage-side arrangement of all the input elements provided for the parameterization of the high-voltage-side control unit, exclusively in a low-voltage circuit, and a galvanically isolating control channel for transmitting the
