PCI/104-Express bus with CAN FD turbo

The PCAN-PCI/104-Express FD allows the connection of PCI/104-Express systems to CAN and CAN FD busses. The PCI/104-Express specification establishes PCI Express for the PC/104 form factor wherewith up to four cards can be stacked. Based on this, standardized modular embedded systems such as industrial PCs can be realized. The CAN bus is connected via 9-pin D-Sub connectors to the supplied slot brackets. There is a galvanic isolation between the computer and the CAN side up to 500 Volts. The card is available as a single, dual, or four-channel version.
