Monitoring circuit for detecting condition discrepancy between redundant components, comprises series electronic switches supplied with switch control signals via respective redundant components

摘要

The monitoring circuit (10) has 2 electronic switch elements (28,38) connected in series across a supply voltage (UB) and controlled via signals (S1,S2) supplied via the monitored redundant components (12,14), the centre tap between the switch elements coupled to an evaluation device (46). An Independent claim for a method for detecting a discrepency between redundant components is also included..
