Wake Industrial LLC is not an authorized distributor of this product.
The Copley Controls 800-1584A is part of the Copley Controls Accessories series and features two galvanically isolated CAN channels with a Sub-D 9M connector. It has a 32-bit PCI bus width, supports a maximum CAN bit rate of 1 Mbit/sec, and measures 142 by 80 millimeters. The device uses a 121 Ohm termination resistor and follows the CAN DS-102 pinout standard.
Internal Product Review
The 800-1584A is a CAN interface accessory for PCI-based control systems, offering 2 CAN channels on a 32-bit PCI bus. Galvanic channel isolation and a 1 Mbit/sec maximum CAN bit rate support clean signaling and dependable network performance in motion and automation applications. A 1 µs timestamp resolution adds strong diagnostic value and makes this Copley Controls module a well-executed connectivity option.

Product Description:
The 800-1584A is a PCI CAN interface board produced by Copley Controls and supplied within the Copley Controls Accessories series. Mounted inside a PC-based automation host, the board links motion drives, I/O modules, and higher-level controllers to a CAN network so that command and diagnostic data can pass over a deterministic fieldbus. The standard PCI edge connector provides the physical connection to the host computer, while CAN signaling supports communication with compatible industrial devices. This arrangement allows Copley servo drives to exchange control and status information with supervisory systems used in manufacturing and test equipment.
The card operates on a 32-bit host bus, enabling direct memory-mapped transfers without narrow data segmentation. Compliance with PCI revision 2.2 supports proper device enumeration, plug-and-play resource allocation, and compatibility with supported industrial PCs. The onboard CAN controller sustains a peak throughput of 1 Mbit/s, allowing it to operate at the fastest arbitration rate supported by the CiA 301 profile. Incoming frames are time-tagged with a resolution of 1 µs, which helps the motion controller correlate drive feedback with precise machine cycles. Each CAN path is galvanically isolated from the PC ground, helping prevent ground loops and improve noise immunity in electrically harsh installations.
The physical layer provides two independent CAN channels through a front-panel 9-pin male Sub-D connector that uses the industry-standard conductor assignment. A factory-installed 121 Ω termination resistor can be enabled with a jumper when the card is located at the end of a network segment. This selectable termination supports proper signal integrity without requiring a separate external resistor at that network endpoint. The board measures 142 × 80 mm, allowing the assembly to fit within a single PCI slot without extending over adjacent modules. Its CAN DS-102 pinout provides a consistent wiring arrangement for compatible CAN cables and connected equipment.
