CAN-4P-PE

4‑channel isolated CAN communication for PCI Express. The CAN‑4P‑PE supports CAN 2.0B at up to 1 Mbps with 300VDC channel‑to‑channel and 1kVDC bus isolation. Large FIFO buffers (64/93 messages) prevent data loss, and included distribution cable simplifies connection to standard 9‑pin D‑SUB networks. Windows/Linux drivers included. From Contec Americas.

The CAN‑4P‑PE is a PCI Express board that adds 4 isolated CAN communication channels to any PC. Compliant with CAN 2.0B and supporting speeds up to 1 Mbps, it is ideal for automotive, industrial automation, and embedded control applications. Each channel has independent FIFO buffers (64 messages per channel + 93 shared transmit / 170 shared receive) to prevent message loss under heavy bus load.

Designed for demanding automotive and industrial CAN networks. The CAN‑4P‑PE features switchable 120Ω terminating resistors per channel and includes a distribution cable that converts the 15‑pin D‑SUB connector to four standard 9‑pin D‑SUB connectors for easy connection to existing CAN networks.

• PCI Express interface – PCI Express Base Spec Rev. 2.0 x1, 256MByte memory address.
• Switchable termination – 120Ω terminating resistor can be enabled/disabled per channel via on‑board switches.
• Included distribution cable – Converts 15‑pin D‑SUB to four 9‑pin D‑SUB male connectors.
• Independent channel operation – Each channel has its own CAN controller for independent communication.
• Surge protection – All signal lines are surge‑protected for robust operation.

No optional accessories are listed in the product datasheet. The distribution cable is included. Standard CAN cables with 9‑pin D‑SUB connectors can be used.
