3. Key Features

1. Dual CAN Channels: Two isolated CAN interfaces enable connection to two independent networks or redundant operation, enhancing system flexibility and reliability.

2. High-Speed Communication: Supports up to 1 Mbit/s baud rate for real-time data exchange, ideal for motion control and high-precision automation tasks.

3. Electrical Isolation: Isolation between channels and backplane prevents ground loops and protects against industrial noise, ensuring stable operation in harsh conditions.

4. Integrated Termination: Software-controlled 120 Ω termination resistors per channel simplify wiring and reduce external components.

5. Configurable RS232 Port: Enables local diagnostics, configuration, and firmware updates without disrupting CAN communication.

6. Robust Industrial Design: Coated PCB and rugged components resist dust, moisture, and vibration, supporting 24/7 continuous operation.

7. Seamless Integration: Plug-and-play installation with hot-swap capability; fully compatible with B&R Automation Studio for configuration, diagnostics, and programming.

8. Diagnostic LEDs: Status indicators for power, CAN communication, and fault conditions on each channel allow quick on-site troubleshooting.

4. Application Scenarios

• Factory Automation: Assembly lines, packaging machinery, and material handling systems connecting PLCs, HMIs, and remote I/O via dual CAN networks.

• Motion Control: Robotics, CNC machines, and servo drive systems requiring real-time, redundant CAN communication for precise coordination.

• Process Control: Pharmaceutical, food & beverage, and chemical industries monitoring sensors, valves, and pumps across distributed CAN segments.

• Redundant Systems: Critical applications needing network redundancy (e.g., power plants, water treatment) to ensure uninterrupted communication.

• Automotive Manufacturing: Production lines and test systems connecting CAN-based ECUs, sensors, and actuators.
