ISO 11898-2 CAN Repeater with 4 kV galvanic isolation
The CAN-CR220 is used for the galvanic isolation of two segments of a CAN bus network and offers a very high galvanic isolation of 4 kV, allowing it be utilized in medical applications. 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 bus segments from each other as well as from the power supply. The CAN-CR220 is tested according DIN/EN 50178 (DIN VDE 0160: 1988-05 and DIN VDE 0160/A1: 1989-04).
