Circuit with programmable connection has evaluation circuit receiving demand and actual signals, outputting signal to indicate deviation between demand and actual measurement states

摘要

The circuit has a programmable connection that outputs an actual signal (E) depending on a current conducting state. A demand signal (D) can be taken from the output of a demand value memory (9) depending on a demand conducting state of the programmed connection and an evaluation circuit (26) receives the demand and actual signals and outputs an indicator signal (F) to indicate a deviation between the demand and actual measurement states.
