Abstract

The device is provided with at least one information line (15, 15') for the transmission of information in the form of analog signals which are derived by a switch point or a sensor (8-11) coupled to the information line (15, 15') and fitted with an address detector (18) for reading address signals via a transformer (I4-I7) that converts the analog signals into a proportional current, wherein the transformer (I4-I7) is connectable to the information line (15, 15') by means of a switch (S1-S4) that is activatable by the corresponding address detector (S1-S4). A reference voltage source (13, 13') for the voltage of the information line (15, 15') is also provided and at least one derivation element (C1-C4) for deriving the overvoltages induced by external interferences from the information line (15, 15').
