CAN repeater with fiber optics (ST) and backbone bus
The Ixxat CAN-CR210/FO repeater with two CAN interfaces, including one fiber-optic interface (ST connector), converts CAN signals from copper to fiber optics. It improves connectivity in areas with high electromagnetic interference and offers the flexibility to optimize network structures. With a built-in CAN backbone bus interface.
Key points
- Robust industrial use — Designed for industrial environments, meeting high requirements for robustness, temperature ranges and safety.
- CAN network design flexibility — Helps optimize CAN network structures by enabling extended topologies (stub lines, star and tree topologies).
- Fast and transparent operation — Minimal impact on real-time behavior, equivalent to a short line length (approx. 60 m/300 ns delay). Transparent transmission, compatible with all higher-layer protocols.
- Savings through simplified wiring — Optimized topologies allow simplified wiring, reducing the number of cables and installation and maintenance costs.
- Increased network reliability — Increased system reliability through electrical isolation of CAN segments and up to 1 kV of power. This strengthens device protection against electronic damage caused by voltage spikes.
- Network monitoring and fault recovery — In the event of a disturbance, the repeater automatically disconnects the affected segment and reconnects it once the fault has been resolved.
- Robust fiber-optic interface — Fiber optics ensure uninterrupted data transmission in areas with high electromagnetic disturbance, providing enhanced connectivity for critical, high-performance applications.
- Backbone bus for simplified network expansion — To create tree or star topologies, several repeaters can be connected in series via the built-in backbone bus, easily linking them to a CAN hub for enhanced connectivity.
- Built-in bus termination resistors — The built-in bus termination resistors (120 Ohm, switchable via DIP switch) prevent reflections at line ends and ensure optimal communication.
