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 network and offers a very high galvanic isolation of 4 kV, allowing it to be utilised 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 the 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. The CAN-CR220 is tested according to DIN/EN 50178 (DIN VDE 0160: 1988-05 and DIN VDE 0160/A1: 1989-04).

Increase reliability

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

For harsh environments

Ixxat repeaters decouple CAN or CAN FD segments galvanically up to 4 kV and are also available as variants with fiber optics.

Save costs

Easier wiring and reduction of cables reduces the cost of your system.
