Abstract

The present disclosure relates to a monitoring assembly for monitoring a supply signal of an electrically operated component, wherein the monitoring assembly comprises a monitoring circuit and a control and evaluation unit assigned to the monitoring circuit. At least one galvanically isolated connection is provided between the monitoring circuit and the control and evaluation unit. The monitoring circuit includes at least one threshold-dependent component which generates a current signal as a function of an applied supply voltage. The supply voltage is an AC voltage. The at least one threshold-dependent component is configured so as to generate a current signal when the supply voltage is above a first threshold value. The control and evaluation unit is set up to evaluate the at least one transmitted output signal to determine a fault condition. The control and evaluation unit is set up to output a drive signal when the fault condition has been determined. A system is furthermore described.
