IXXAT CAN-CR220 - CAN Repeater with isolation
The Ixxat CAN-CR220 repeater with 2 CAN interfaces provides galvanic isolation which enhances the protection of network segments. Designed for industrial environments, this device meets high demands for robustness, temperature ranges, and safety. It improves the CAN bus load capacity, establishes a physical coupling of bus systems, and provides the flexibility to optimize network structures. It meets DIN/EN 50178 standards. Protection and Reliability Equipped with 2 CAN channels, the CAN-CR220 can be used to establish a physical coupling and galvanic isolation of two segments of both CAN bus systems. System reliability by electrically isolating CAN segments and power, ensures auto-separating network faults and keeping the network operational. In case of disturbances in the CAN lines, the repeater automatically disconnects the affected segment and restores it after the fault is resolved, ensuring uninterrupted network operation. Network Design Optimizing CAN network structures helps to enable extended layouts (stub lines, star and tree topologies). Optimized topologies enable simpler wiring, resulting in less cables and cost savings at installation and maintenance. Fast Transparent Operation Minimal impact on real-time behavior, equivalent to a short line length (ca. 40 m/200 ns delay) enables transparent transmission, compatible with all higher layer protocols. Termination Resistors Integrated bus termination resistors (120 Ohm, switchable via DIP switch) prevent reflections on the line ends and ensure optimum communication.
