Safety-related functions e.g. brake functions, controlling device for rail vehicle, has direct current/direct current transducer arranged between control device and power supply to convert voltage of supply to voltage level of device

摘要

The device (1) has a safety control device (6) supplied with electric power via an on-board power supply (3) of a rail vehicle (2). A direct current (DC)/DC transducer (7) is arranged between the control device and the supply to convert voltage of the supply to a voltage level of the control device. The control device has electrically insulated electrical portions to control safety-related functions (4). A network terminal (8) is connected with a data converter (16), which converts secured data of the control device into data for data transfer over a non-safe data transmission system (10).
