Claim:
1. A device for monitoring and switching a load circuit, having: a) an input part and an output part, b) switching inputs to connect a controller to the input part, c) switching outputs to connect at least one load circuit with at least one load to be switched to the output part, d) at least one load switch for switching, in particular for switching on and off, the at least one load, wherein e) the input part has an input circuit which converts switching commands of the controller incoming via the switching inputs into switching processes of the load switches, f) having at least one fault detection circuit to detect a fault in the load circuit and to generate at least a first fault signal in the output part and g) a galvanic isolation stage for galvanically isolated transmission of at least one of: this first fault signal or a second fault signal derived from this first fault signal from the output part to the input part, h) wherein the transmitted fault signal is made available via the switching inputs for evaluation.
