Abstract
The present invention relates to an electronic safety switching device having at least a first and a second signal processing channel. The channels can be supplied with input signals for signal processing, and they provide redundantly processed output signals. According to one aspect of the invention, the signal processing channels are arranged monolithically on a common semiconductor substrate. The semiconductor structures of each signal processing channel are spaced apart physically by a multiple of their width from the semiconductor structures of every other signal processing channel.
