CAN and CAN FD Repeater for the Decoupling of Bus Segments

PCAN-Repeater DR

IPEH-004038

Description

The PCAN-Repeater DR establishes a connection between two High-speed CAN buses with galvanic isolation of up to 5 kV. Both CAN channels are decoupled from each other and from the power supply. All message traffic including error frames is forwarded 1:1 between both channels, if necessary, in one direction only. The PCAN-Repeater DR behaves passively and is transparent from the perspective of the CAN bus. LEDs display the current bus status. With its DIN rail casing and extended temperature range support, this module is suitable for use in an industrial environment.

The PCAN-Repeater DR can be used in CAN FD buses with data bit rates up to 4 Mbit/s and nominal bit rates up to 1 Mbit/s.


Please Note:

Due to the CAN protocol, the maximum length of a CAN bus depends on the bit rate. Therefore, a bus cannot be extended with the PCAN-Repeater DR. The physical total length of the CAN bus is reduced with each built-in PCAN-Repeater DR according to its signal delay.
