CAN-CR220

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 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 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).

Line protection up to 4 kV
