Abstract
The invention relates to a safe electronic device which has multichannel logic circuitry, a single channel input device, an output device, and a storage device. Data items, each of which is associated with an input value, are stored in the storage device. The multichannel logic circuitry is comprised of a first control unit and a second control unit. The first control unit reads in an input value which has been input, and transmits the input value to the second control unit which actuates the output device for outputting of optical and/or acoustic information, in response to the input value which has been input. If the optical and/or acoustic information corresponds to the input value, the selected data item is released for further use.
