The Ixxat CAN-CR220 repeater with two CAN interfaces provides a galvanic isolation up to 4 kV DC/3.5 kV AC for 1 second, enhancing the protection of network segments. It improves the CAN bus load capacity, establishes a physical coupling of bus systems and provides the flexibility to optimize network structures. The CAN-CR220 meets DIN/EN 50178 standards.

Features and benefits

Robust industrial use
Designed for industrial environments, meeting high demands for robustness, temperature ranges, and safety.

Flexibility in CAN network design
Helps to optimize CAN network structures by enabling extended layouts (stub lines, star and tree topologies).

Fast and transparent operation
Minimal impact on real-time behavior, equivalent to a short line length (ca. 40 m/200 ns delay). Enabling transparent transmission, compatible with all higher layer protocols.

Cost savings due to simple wiring
Optimized topologies enable simpler wiring, resulting in less cables and cost savings at installation and maintenance.

Increased system protection up to 4 kV DC/3.5 kV AC for 1 sec.
Using the CAN-CR220, network components can be galvanically isolated up to 4 kV DC/3.5 kV AC for 1 second (3.2 kV DC/2 kV AC for 1 minute). This reliably enhances the protection of the device against damage to electronics caused by voltage peaks.

Network monitoring and fault recovery
In case of disturbances, the repeater automatically disconnects the affected segment and restores it after the fault is resolved.

Integrated bus termination resistors
Integrated bus termination resistors (120 Ohm, switchable via DIP switch) prevent reflections on the line ends and ensure optimum communication.
