A measuring transducer supply unit for use in automation technology, which makes the connection of at least one field unit to a superordinate unit by means of a two-wire line possible, wherein the measuring transducer supply unit comprises at least a switch, a radio module, and a circuitry. The radio module can be activated or de-activated by means of the switch, and the circuitry realizes the conversion between signals of the two-wire line and signals of the radio module such that the at least one field unit connected to the measuring transducer supply unit via the two-wire line can be operated by wireless communications connection by means of the radio module.
