CAN / CAN FD repeater with screw terminals
and 3 kV galvanic isolation
Product announcement: Available from April 2019

The CAN-CR120/HV is used for galvanic isolation of two segments of a CAN / CAN FD network. As a special feature, the repeater separates a defective segment from the rest of the network, allowing the remaining network to continue working. After the fault has been eliminated, the segment is automatically switched back to the network. The galvanic isolation is provided for the CAN / CAN FD segments as well as for the power supply.
