CAN-CR200
Modular ISO 11898-2 CAN repeater
with backbone bus
The CAN-CR200 is used for the galvanic isolation of two segments of a CAN network and for creating star or tree topologies. Several CAN-CR200 can be connected to a CAN-hub via the integrated backbone bus. One special feature of the Repeater is the automatic recognition and separation of a defective segment from the rest of the network so that the remaining network can continue working. After elimination of the defect, the segment is switched into the network again.
The galvanic isolation isolates the CAN segments from each other as well as from the power supply.

Features and benefits
- DIN-Rail backbone bus to line up and connect the devices easily
- Cost savings due to simple wiring
- Increased system reliability
- Almost no influence on real-time behavior

Learn more about the repeaters and see how they work
The lines coupled by the repeater are independent electric segments that can be optimally terminated in terms of signals. In this way topologies can be implemented that are not possible with a pure line of the bus due to electrical reflections. According to the transceiver output capacities, the division of a CAN / CAN FD system into several subsystems, connected via CAN / CAN FD repeaters, increases the maximum number of bus nodes. Using repeaters does not influence the real-time behavior of a system because in terms of transmission behavior it corresponds to a network that consists only of lines. In terms of signals, the repeater corresponds to a line with relevant delay time. Therefore, it cannot be used to extend a CAN / CAN FD system. However, using repeaters allows to increase the system dimensions indirectly, as shown in the sample.
