Abstract
A safety circuit for the multi-channel processing of an input signal. The safety circuit includes an analog-to-digital conversion device having a first analog input and a second analog input and at least one digital output for processing the input signal. Furthermore, the safety circuit has a test device which is set up to apply a test signal at the first and/or second input of the A/D conversion device in such a way that the test signal superposes the input signal such that the test signal dominates the input signal.
