Abstract: A safety system comprises separate safety circuits connected to a process to be safeguarded, each of which safety circuits are coupled to a data acquisition circuit via a retroaction-free element, which takes care of it that in the event of a malfunction occurring on the input of the data acquisition circuit, this malfunction will not affect the reliability and operational safety of each of the separate safety circuits.
