Protocol converter CAN FD to RS232 RS485 bidirectional

The CAN FD TO RS232/RS485 is a bidirectional protocol converter for DIN rail mounting that connects CAN FD networks with serial RS232 and RS485 interfaces. The device supports five data conversion modes: transparent conversion, transparent conversion with ID, standard protocol conversion, Modbus protocol conversion, and custom protocol conversion. The converter is compatible with CAN FD as well as the older CAN 2.0A and CAN 2.0B protocols. The industrial-grade design allows operation at temperatures from -40°C to +85°C and accepts a wide input voltage range of 9 V to 36 V DC.

Features:

• Bidirectional conversion between CAN FD and RS232/RS485 interfaces
• Five conversion modes including transparent and Modbus protocol conversion
• Industrial-grade design for operating temperatures from -40°C to +85°C
• Wide input voltage range of 9 V to 36 V DC for flexible power supply
• Integrated 120 Ω termination resistors can be switched via DIP switch
• DIN rail mounting for easy cabinet integration

Application Examples:

• Integration of CAN-based sensors into Modbus networks
• Connecting vehicle diagnostic systems with serial interfaces
• Industrial automation with mixed bus systems
• Retrofit older RS485 installations with modern CAN FD devices
• Data acquisition and logging of CAN bus messages
