Abstract

A supply module includes an electrical control input and an electrical supply input as well as an electrical control output and an electrical supply output, as well as a control line arranged between the control input and the control output, which is designed for the transmission of control information, wherein at least one supply line group is assigned to the electrical supply input, which group includes a supply feed line and a supply outlet line, which are each extended between the electrical supply input and the electrical supply output, and which includes a switching module which is coupled to the control line and which has a feed switch arranged in the supply feed line, wherein a consumer output is formed for an electrical supply of an external consumer and is connected via an output feed line to the supply feed line and via an output drain line to the supply outlet line, the output feed line being connected between feed switch and the electrical supply output.

First claim

What is claimed is:

1. A supply module comprising a module housing having a first coupling surface a second coupling surface, wherein an electrical control input and an electrical supply input are arranged on the first coupling surface and wherein an electrical control output and an electrical supply output are arranged on the second coupling surface, with a control line arranged between the control input and the control output, which is designed for the transmission of control information, wherein at least one supply line group is assigned to the electrical supply input, which comprises a supply inlet line and a supply outlet line, each of which extends between the electrical supply input and the electrical supply output, and which comprises a switching module which switching module is coupled to the control line and which has a supply switch arranged in the supply inlet line for selectively connecting and disconnecting the supply inlet line, wherein a consumer output is arranged on a side surface of the module housing, which consumer output is designed for an electrical supply of an external consumer and is connected to the supply inlet line via an output feed line and to the supply outlet line via an output drain line, the output feed line being connected to the supply inlet line in a region between the supply switch and the electrical supply output.

2. The supply module according to claim 1 , wherein at least two supply line groups are assigned to the electrical supply input.

3. The supply module according to claim 1 , wherein the switching module comprises a drain switch arranged in the supply outlet line for a selective connection and interruption of the supply outlet line and that the output drain line is connected to the supply outlet line in a region between the drain switch and the electrical supply output.

4. The supply module according to claim 1 , wherein a processing unit is provided for coupling the switching module to the control line, which processing unit processes control commands being provided via the control line.

5. The supply module according to claim 4 , wherein the processing unit actuates the feed switch and the drain switch to power off an electrical power supply to the consumer output, and actuates the supply switch and the drain switch or only the supply switch or only the drain switch for switching off an electrical power supply to the electrical supply output.

6. The supply module according to claim 1 , wherein a protective circuit is associated with the output feed line and/or the output drain line, which protective circuit prevents electrical energy from being coupled from the consumer output to the electrical supply input and/or the electrical supply output.

7. The supply module according to claim 6 , wherein the protective circuit comprises a diode arranged in the output feed line and/or a diode arranged in the output drain line.
