Abstract

The circuit configuration according to the invention comprises an electrical signal line loop, several partial systems connected thereto, which evaluate the state of the signal line loop, wherein a first selectable switching means is looped in between a first end of the signal line loop and a first voltage connection and a second selectable switching means is looped in between a second end of the signal line loop and a second voltage connection, and a selection unit for selecting the first and second switching means. Use, e.g. in a fuel cell system.
