Technical¶

Variants¶

Smart CAN Isolator is offered with two versions: Smart CAN Isolator and Smart CAN Isolator OEM. Smart CAN Isolator is protected by an enclosure made of ABS polymer. The OEM version is smaller, lighter and has better heat dissipation; but requires mechanical protection when installed.

Block Diagram¶

The following block diagram summarizes the functionality of the system and gives an overview of the redundant power supply scheme.

Mechanical Specifications¶

Smart CAN Isolator is provided using an ABS polymer enclosure with IP 67 protection. The approximate total weight without cable harness is around 50g without clamps and 66g with 2 clamps.

Inside the Smart CAN Isolator there are not included any navigation sensors, this implies that there are no constraints regarding vibration isolation, location or orientation of the Smart CAN Isolator.

The following figures show the dimensions of the device.
