Abstract
A device () for safe data transmission to railway beacons has a first and a second circuit section () independent of and galvanically separate from each other, and each having: a microprocessor () selection stage () receiving information signals relative to the status of a portion of a railway line, and generating at least one telegram for transmission to a beacon; and a control stage () comparing the telegrams generated by the first and second circuit section () for enabling/disabling data transmission to the beacon. The first circuit section () also has a transmission enabling stage (), which allows transmission to the beacon of the telegram generated by the first circuit section (), in the event the comparison performed by the control stage () is successful.
