Repeaters

For a more flexible networking and increased
communication reliability in CAN and CAN FD systems.


Ixxat repeaters are established successfully in many different application areas, whether in test benches for communication networks or in production systems. Using repeaters, network segments or components can be galvanically isolated, long drop-lines or tree/star topologies can be implemented and the robustness and reliability of the network can be increased.
If you want to expand the distances you should use one of Bridge/Gateway/Router solutions.

CAN / CAN FD Repeaters
HMS_web-icon_High performance

Increase reliability

CAN and CAN FD repeaters increase your system reliability with almost no influence on the real-time behavior.

HMS_web-icon_diagnostic

For harsh environments

Decouple CAN or CAN FD segments galvanically with up to 4 kV or use variants with fiber optics.

HMS_web-icon_protocol-translator

Simplified networking

Repeaters enable star and tree topologies as well as large drop lines. 


CAN-CR120/HV

CAN / CAN FD repeater with screw terminals
and 3 kV galvanic isolation

The CAN-CR120/HV is used for galvanic isolation of two segments of a CAN / CAN FD network. As a special feature, the repeater separates a defective segment from the rest of the network, allowing the remaining network to continue working. After the fault has been eliminated, the segment is automatically switched back to the network. The galvanic isolation is provided for the CAN / CAN FD segments as well as for the power supply.
