Abstract
The invention relates to an electrical device with a logic circuit and with a storage medium which is connected to the logic circuit and in which data are stored. The storage medium is provided with a data link via which data can be read out outside the device with the aid of a reader. The storage medium can also be a RFID transponder to provide data via radio link to be read by a reader outside of the device.
Claims8
An electrical device comprising:
- a direct current transducer having an input and an output, wherein the input is electrically connectable from outside the electrical device;
- a logic circuit electrically connected to the direct current transducer;
- a bus connector electrically connected to the logic circuit;
- a storage medium electrically connected to the logic circuit via a data link, wherein the data link is electrically connected to an interface accessible from outside the electrical device, wherein the storage medium is electrically connected via a diode to the output of the direct current transducer;
- and wherein the storage medium comprises, data storage means, and the data link provides data to be read out with the aid of a reader outside the electrical device;
- and
- a branch from the electrical connection between the diode and the storage medium to a power supply connector accessible from outside the electrical device.
