<p>Coupling circuit (1) for transferring data from a data transmitter (2) to a bus (3) common to several transmitters so that each data transmitter is galvanically separated from the bus. The coupling circuit (1) has a switch (15, 16) connected in series between each associated input (26, 27) and output (28, 29), which switch via a rectifier circuit (17, 19, 21 and 18, 20, 22) in the coupling circuit (1) is controlled solely by the data signals transferred from the data transmitter (2) via separator means (14, 24, 25). </p> |
