Abstract:
A safety switching device (1) for monitoring system operating states, which is set up for the connection of at least one signaling device (28) which has at least two switching states, in which case the signaling device (28) is selected from a set of signaling devices (28a . . . 28g) which are intended for connection to the safety switching device (1) and which have different numbers of break and/or make contacts (29,31,35,36,37,38,39,46,47,48),having a set of inputs (E1 . . . E16) to which the signaling devices (28) can be connected, in which case defined inputs (E1 . . . E16) are assigned to specific signaling devices (28),having at least one output (A) which is provided jointly for a plurality of the signaling devices (28), andhaving an identification device (2) for identifying the respective signaling device (28) from the set of possible signaling devices (28a . . . 28g).
