Abstract
The present invention relates to a device and a method for measurement of electrical signals in an industrial automation and control system. The device comprises an input circuit, configured to receive an electrical input signal (), scale the electrical input signal by a scaling factor and to set the scaling factor according to a scaling signal (), an Analog-to-Digital Converter, ADC (), which is electrically connected to the input circuit, wherein the ADC is configured to convert the scaled electrical input signal () into an intermediate digital signal (), and a first signal path (), connected to an digital end of the ADC, configured to create the scaling signal () and to send the scaling signal () to the input circuit, wherein, based on the intermediate digital signal of a sample period and the scaling factor of the sample period, the scaling factor for a subsequent sample period is set.
