CAN Repeaters

CAN repeaters are transceiver based devices that allow CAN networks to be extended by regenerating the CAN bus signals. They are particularly useful in establishing more advanced network topologies, stub-lines, trees, and stars being examples, with a view to increasing flexibility and reducing the size and cost of a CAN system.

Basic Function

The CRep S4 4-channel CAN Repeater transmits and amplifies signals transparent to the CAN protocol. Each of the four CAN connections has the physical behavior of a single bus node. CRep S4 permits a flexible design of the network topology and offers special support for star structured networks.

CAN Repeater

The Crep S8C is a modular and cascading 8-channel CAN repeater which provides support for even more complex topologies, capable of accommodating up to 24-channels with low latency. Originally developed to support factory environments in the paper industry, Traquair now offers this either as an off the shelf product, or as a semi-custom mezzanine module (tailored to customer / application specific requirements).

  • 24V power supply

CAN Requirements Beyond Repeaters?

These products are part of an extensive range of PC interfaces & adapters, repeatersgatewaysfiberoptic transceivers, and distributed I/O interface products for CAN. Together, the entire CAN product range provides developers with a compressive toolkit for implementing a diverse range of CAN system capabilities.
