Compressed air brake device for a rail vehicle with a direct electropneumatic brake

A compressed air brake device for a rail vehicle with a direct electropneumatic brake, the device comprising:

• a brake control unit having a brake control device with connected brake actuators and a brake pilot control pressure sensor connected to the brake actuators;
• a pressure converter that is loaded with a brake pilot control pressure by the brake actuators and is connected to at least one downstream brake cylinder;
• an independent monitoring control unit connected in parallel with said brake control unit, said monitoring control unit having a monitoring control device with connected monitoring actuators and a monitoring pilot control pressure sensor connected to the monitoring actuators;
• said monitoring pilot control pressure sensor controlling a monitoring pilot control pressure at an output of said monitoring actuators, wherein in each case a higher pressure of the brake pilot control pressure and the monitoring pilot control pressure, or, if a fault is present in said brake control unit, the monitoring pilot control pressure, is relayed to the brake cylinder;
• and
• a pressure sensor having an input connected to said pressure converter and an output connected to said monitoring control device of said monitoring control unit.
