Abstract
Apparatus for voltage monitoring of a dual-channel device which implements or monitors a safety function of a machine or technical installation. The apparatus comprises an input for receiving an input voltage, a voltage regulator for generating a defined output voltage, and an output for providing the defined output voltage for the operation of the device. A voltage monitor compares a voltage present at the output with the defined output voltage and switches off the output in case the present voltage at the output deviates from the defined output voltage. A first interface and a second interface connect the voltage regulator to the dual-channels of the device, wherein the first interface and the second interface connect to a first processing channel and a second processing channel of the device separately so that the first processing channel and the second processing channel of the device can detune the voltage regulator independently.
