  • Note: We have verified to drive 100 CAN nodes at the same time via one CAN port of I-7531.


The I-7531 is an isolated CAN repeater that can be used to establish a physical coupling of two segments of a CAN bus system. This module is designed to isolate the noise and disturbance between the two CAN ports of the I-7531. When the CAN signal is decayed because of the rough bus cable or noise, the I-7531 can recover the shape of the CAN signals to the original ones. Tree topologies can be implemented as well as long drop lines using the I-7531. In order to use the I-7531 easily, the module can automatically adjust the baud rate by itself to match the CAN network. Users just connect the I-7531 with the CAN buses, check the terminal resistor and power it on, subsequently the I-7531 enable to work normally. For detail information , please refer to the user manual of I-7531.
