Abstract
A module for a programmable controller includes a plurality of analog input channels, a control and evaluation device, and input terminals, where for each input channel, the module includes two analog to digital converters, at least four coupling elements and a switchover device, where for each input channel, where an input side of one analog to digital converter is directly or indirectly connected with the input terminals and an output side is connected with the evaluation circuit via a coupling element, where a control input of the switchover device is connected with the switching signal generator via a further coupling element, a signal output of the switchover device is connected with an input side of the other analog-to-digital converter, and where an output side of the other analog-to-digital converter is connected with the evaluation circuit via a further coupling element, where the coupling elements cause electrical isolation.
