Receiving unit for bus signals on a two-wire bus and method of installing a two-wire bus

摘要

The bus signal reception unit (3) has a detection device which discriminates between bus signals and a bus short-circuit, coupled to a switching device for on-off switching of a voltage supply stage for the 2-wire bus. The detection device may incorporate a voltage polarity protection function for disconnection of the bus supply stage. Also included are Independent claims for the following; (a) a bus signal terminal; (b) a 2-wire bus; (c) an application of a bus signal reception unit in a building installation; (d) an installation method for a 2-wire bus; (e) an application of a 2-wire bus installation method to a building installation
