Abstract
A digital input unit for an automation device includes at least one current drawing DC input channel for connecting a transducer operated at a nominal DC voltage, where the input channel is configured to set the current based on an input voltage (UEM) according to an input characteristic curve. Measures are proposed, as a result of which the digital input unit is suitable for connecting transducers of different supply voltages, where the digital input unit is operable with a reduced power loss.
