To automate your system, it is essential to install a well-functioning feedback system. 

The main function of the Z21 DETECTOR is the feedback message via current monitoring on 8 track sections. This essential function is possible via R-BUS and CAN. This means that the 10808 can be used both on the black Z21 and on the white z21 and the z21start.

The address of the feedback module can be set very easily using the integrated programming key. The status of each input is displayed via a separate status LED.

The CAN-BUS on the black Z21 offers even more:
  • Locomotive identification via RailCom® Local Detector on each of the 8 inputs, and all at the same time. This means you always know which locomotive is located in which section.
  • The RailCom® Local Detector via CAN also provides the option of POM reading in booster sections where a RailCom cut-out is being produced, but where there is no RailCom® Global Detector in the booster itself. This is the case with the Z21 light BOOSTER, for example.
  • Response characteristics, current thresholds, RailCom® settings and the address can be easily configured via the Z21 Maintenance Tool.
  • The firmware update for future features can also be carried out easily and quickly using the Z21 Maintenance Tool.
