Abstract (en)
[origin: DE10235527C1] The redundant voltage supply arrangement has at least one first drive device (1) and second and third drive devices (2,3), each for driving relays in relay unit (4) to change over voltage supplies for safety-relevant systems (5). The drive devices are connected to a communications channel (11) and the first and second drive devices each have a device for monitoring a voltage on a safety-relevant system. AN Independent claim is also included for the following: a method of providing a redundant voltage supply for safety-relevant systems.
