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.
