Product Description

The MW-CANFiber500 is a CAN-bus to Ethernet fiber card-mounted CAN server, capable of CAN to optical fiber and CAN to Ethernet conversion. It extends the transmission distance of CAN buses and allows centralized management through a network. This product provides 1 100M Ethernet port and 2 CAN ports and supports multiple power input options, including AC85264V / DC110370V AC or DC9~60V DC.


The product is designed with high-quality components, adheres to high standards in system design and production control, and can be easily installed on a 35mm standard DIN rail. It features a robust and durable high-strength metal casing, fanless heat dissipation, and can operate in a wide temperature range from -40°C to +85°C. With its high-standard industrial protection design, it can adapt to various challenging working environments, ensuring stable communication performance.


MW-CANFiber500 supports various network management functions through web configuration, including CAN/network operating modes, CAN statistics, network addresses, network diagnostics, user passwords, system information, and system management. It also supports multiple conversion modes such as UDP, TCP Client, TCP Server, UDP multicast, enabling CAN to Ethernet protocol conversion, connecting CAN bus networks to Ethernet networks.


The product has undergone rigorous testing for functionality, temperature extremes, safety standards, and EMC compliance, making it suitable for complex network applications and demanding industrial environments. It can be widely used in industries such as automotive, industrial automation, IoT applications, energy management, enabling remote monitoring and control, data collection, and integration.
