CAN528 high-performance CAN(FD) and Ethernet gateway integrates two CAN(FD) interfaces, one Ethernet interface, one SFP slot and one serial port. In terms of software, it integrates the TCP/IP protocol stack and supports TCP/UDP/MQTT protocols. Moreover, it supports CAN(FD) to Modbus and CANopen to Modbus protocol conversions. Users can easily achieve interconnection and interoperability between the CAN bus network and the Ethernet network, and further expand the application scope of the CAN FD network.

Key Features
- Rich Interfaces: 2*CAN, 1*Gigabit Ethernet, 1*SFP Slot, 1*RS485
- Industrial Designed: Isolation for all interfaces, DC 9-70V power input, -40 ~ 85℃ wide temperature
- CANopen Protocols: CANopen to Modbus, CAN/CANFD to Modbus
- CAN Features: CAN(FD) to Ethernet/RS485/Fiber Optic, CAN repeater


CAN to Ethernet Conversion, Two-way Communication
-
- · TCP client, TCP server, UDP client, UDP server, MQTT client are supported
- ·In TCP client/MQTT client mode, it supports TLS encryption
- ·Supports 2 sockets so it can communicate with 2 different servers
-
Modbus RTU/TCP Gateway.
-
CAN528 supports CAN to Modbus TCP/RTU conversion, and it can work as both modbus slave or master mode. With this function, users can active data acquisition or read/write control of Modbus devices via the CAN bus.

CAN to Fiber Optic Converter .CAN528 has one standard SFP Gigabit fiber optic port which enables fast transmission over long distances.CAN Repeater . CAN528 comes with 2 channel CAN ports, so it can work as a CAN repeater to extend communication distance and expand bus nodes.
CANopen Master to Modbus TCP/RTUUSR-CAN528 can act as a CANopen master, converting CANopen communication into Modbus RTU/TCP. It enables industrial devices (like robotic arms) on a CANopen network to be monitored and controlled by higher-level systems such as PLCs, SCADA, or cloud platforms via Modbus.
Designed for Demanding Industrial Environments
- DC 9–70V wide voltage input, compatible with various field conditions.
- Complete isolation of power, CAN port, Ethernet port, and serial port, up to 3000VDC
Typical Application – BMS ManagementThe BMS (Battery Management System) acts as the “intelligent manager” of the battery, and its core function is to ensure that the battery system operates safely, reliably and efficiently, and to maximize its service life. It manages the battery comprehensively through real-time monitoring, intelligent analysis and active control.
