CAN-CR120/HV
CAN / CAN FD repeater with screw terminals
and 3 kV galvanic isolation
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.
Line protection up to 3 kV

Display Transmit and defective segment (two duo LEDs, one for each segment),
Power (one LED)
CAN bus interface ISO 11898-2 with CAN choke. Two screw terminals.
Available with and without integrated CAN termination.
CAN bitrates Up to 1 Mbit/s
CAN FD bus interface ISO CAN FD and nonISO CAN FD
CAN FD bitrates Arbitration rate up to 1000 kBit/s, data rate up to 8000 kbit/s. The data rates are verified by
tests. User-defined bit rates are possible.
Attention: The maximum data rate can be exceeded depending on the concrete operating
conditions (cable length, settings made, remote stations,...), but it can also not be reached.
Delay typ. 175 ns (corresponds to ~35 m bus length)
Power supply 9-36 V DC, typ. 70 mA, max. 100 mA, through terminals
Galvanic isolation 3 kV DC / 1 sec, 1500 V AC / 1 min; CAN 1, CAN 2 and
power supply are galvanically isolated from each other.
Certification CE, FCC
