CAN FD to USB interface adds galvanic isolation

CAN to USB interface, redesigned
The U100 from Kvaser is a single-channel CAN/CAN FD to USB interface with reinforced galvanic isolation for automotive, marine, industrial, heavy duty vehicle and heavy industries.

Kvaser in Sweden has redesigned its rugged Leaf CAN to USB interface to address higher voltage environments with galvanic isolation and sustainability requirements.

The U100 is compatible with J1939, CANopen, NMEA 2000 and DeviceNet and is the product is the first of a future range of interfaces from Kvaser suited to rugged applications. With enhanced protection of its own electrical circuits, a vibration, shock and drop-proof housing and high-quality cabling, the U100 establishes a new reference in CAN interface design. Connected to a system with different electrical potentials, the Kvaser U100 mitigates the risk of disturbance caused by current leakage to measurements on the system under test.

Innovations in the design include two LED bars showing CAN traffic status: busload, error frames and overrun. The U100 also features a connector with inverted strain release that handles more force than previous models when pulled or bent. PC- or CANbus- side cable replacement can be carried out by an authorised Kvaser party without compromising IP67 integrity, reducing cost over the product’s lifecycle and enabling fast delivery of custom configurations.

The U100 (EAN 73-30130-01173-1) has a 9-pin D-SUB connector. Other members of the product line with J1939-13 Type II (01266-0), M12 (01267-7) and OBD-II (01268-4) connectors will be available soon.

The U100 supports CAN FD up to 8 Mbit/s with correct physical layer implementation with 20,000 msg/s, each time stamped with a resolution of 100μs. The reinforced galvanic isolation allows the design to be validated with 5000 VAC RMS applied for 60 seconds. It is IP67 rated with a rugged housing and operation from −40 ºC to +85 ºC

The device is supported on Windows and Linux (incl. SocketCAN) and fully compatible with applications written for other Kvaser CAN hardware with Kvaser CANlib.
