ROTATIONAL-ANGLE DETECTION SYSTEM FOR DETECTING THE ROTATIONAL ANGLE OF A ROTARY BRAKE DRIVE FOR A RAIL VEHICLE

A rotational-angle detection system detects the rotational angle of a rotary brake drive for a rail vehicle and includes at least one sensor unit for detecting a rotational angle, which is operatively connectable to the rotary brake drive, and at least one electronics main path and at least one electronics safety path for each sensor unit, wherein the at least one electronics main path and the at least one electronics safety path is each operatively connectable to the at least one sensor unit as an individual path, wherein the at least one electronics main path and the at least one electronics safety path each includes at least one signal provision unit.
