The CAN-11 is a cost-effective industrial-strength CAN Bus isolated repeater, widely used in automotive electronics, industrial automation equipment, security systems, intelligent instrumentation, and other applications. The module provides 1.5KV electrical isolation, bidirectional bus arbitration, baud rate adaptive design, protocol transparency, and plug and play. The product comes with a modular design, small in size and light in weight. The repeater is suitable for standard 35mm DIN rail mounting. The terminals are detachable, saving space and time for easy construction of a durable and protected CAN Bus network.
- Industrial grade CAN bus isolated repeater, 100Mbps high speed isolation
- Standard 35mm DIN rail mounting, 9-28VDC wide voltage supply
- Supports CAN2.0A/B Standard (optional support for the latest CAN-FD standard)
- Slim modular design with detachable terminals
- Magnetic coupling isolation technology, 1.5KV electrical isolation, interface surge protection
- Power supply, CAN Bus pre-stage and rear-end three-terminal isolation
- Built-in bus arbitration logic, bus data LED indication;

Failure isolation function:
CAN-11 provides fail-isolation. When one end of the bus data continues to be "dominant", the other side of the transceiver will trigger the dominant timeout (DTO) function, thereby isolating the failed side bus, ensuring that the typical side bus node remains in Normal communication.

High noise levels on a CAN bus network have the potential to destroy CAN bus transceivers. This noise originates mainly from two sources, ground loops and electrical line surges. Protecting a network against this destructive energy requires the galvanic isolation of the CAN bus system from other local node circuitry.
