Industrial 8-Port CAN Bus over Fiber Converter

View : 677
Type : CAN bus fiber modem
Description :

This product adopts a large-scale FPGA design, which can support 8 channels of CAN1.0/2.0 bus to fiber optic relay at the same time.


This device adopts a large-scale FPGA design and can simultaneously support 8 channels of CAN 1.0/2.0 bus to fiber optic relay. It features innovative technology where the CAN rate is not affected by the length of the fiber optic cable, and the CAN communication baud rate is self-adaptive from 0 to 1 Mbps. The fiber optic length can range from 0 to 120 km, and it supports point-to-point communication over fiber optics.


With an IP40 rating, it is housed in a rugged aluminum casing with corrugated waves, designed for enhanced durability. It can be conveniently mounted on a 35mm DIN rail and accepts wide power input ranging from AC to DC (9~55V), offering power redundancy and isolation protection. It operates within a temperature range of -40 to 75°C, making it suitable for various industrial environments. This device provides a convenient fiber optic communication solution for meeting the requirements of different industrial field applications.
