Abstract

A bus system comprises a data line having a first channel with a first pair of wires and a second channel with a second pair of wires. The first channel connects a physical feed module interface to a physical consumer module interface and a first DC voltage source to a first consumer module DC voltage consumer, to transmit a first differential data signal between the feed module interface and the consumer module interface and a first direct current from the first DC voltage source to the first consumer module DC voltage consumer. The second channel connects the feed module interface to the consumer module interface and a second DC voltage source to a second consumer module DC voltage consumer, to transmit a second differential data signal between the feed module interface and the consumer module interface and a second direct current from the second DC voltage source to the second consumer module DC voltage consumer.
