Abstract
An electronic device, e. g. a measuring transducer, has an interface circuit for communicating with and receiving power from a two-wire line, said interface circuit has a modulator connected to the two-wire line and responsive to an information signal for modulating the current in the two-wire line according to the information signal, and further has a controllable switching type DC-to-DC converter for extracting power for the electronic device from the two-wire line. To reduce energy losses, the DC-to-DC converter is designed to be controlled by said information signal and to perform the function of the modulation means.
