Two-channel Isolated CAN / CAN FD Signal Repeater
The I-7531-FD-G is an isolated CAN/CAN FD signal repeater with two CAN ports, that can connect and isolate two CAN signals with the same CAN baud rate. When the CAN signal received by one of the CAN ports is attenuated due to cable length or noise interference, this module can restore the CAN signal to its original shape and output it from the other CAN port. Additionally, the module can automatically adjust its CAN baud rate to match the CAN bus, so users do not need to configure any module parameters. Users only need to connect the module to the CAN bus, supply power, and it will function normally.
However, please note that although the attenuated CAN signal can be restored to its original shape after passing through this module, there will be a slight time delay at the physical layer, and the communication distance of the CAN signal will not be extended. If users need to extend the communication distance of the CAN signal, please refer to the I-7532M-FD.
