CAN Router
With special vehicle concepts such as e.g. Eurocombis or Roadtrains, the utilisation
of multiple Trailer EBS systems on different axle units or trailer modules is required.
To supply the brake modulators with CAN signals in accordance with ISO 11992 and
supply voltage, an additional device is required. WABCO provides a solution in the
CAN Router, with which up to four CAN routers in series can supply up to five Trailer
EBS modulators.
The CAN brake signal of the towing vehicle is received by the CAN Router and
distributed to the Trailer EBS modulators.

pressure sensor
If the CAN signal of the towing vehicle is not available, a pressure sensor that can be
connected as an option generates the control pressure for the yellow hose coupling
as a CAN signal and sends it through the CAN router to the Trailer EBS E1 modulator
connected to the "Power OUT1" output to optimise timing.
