Product Description:

The C6640-0000 is an industrial PC produced by Beckhoff as part of the C6 Industrial PC Units series. Mounted inside a control cabinet, this unit acts as the central computing platform for PLC logic, motion control, and visualization tasks within automated machinery lines. Its purpose is to consolidate real-time processing and field-level communication into one compact device so that machine builders can coordinate drives, I/O, and operator interfaces from a single hardware node.

The enclosure spans 371 mm in width, 336 mm in height, and 198 mm in depth, dimensions that fit standard 19-inch cabinets. With a mass of 11 kg, it requires secure panel mounting points to support static load and cable strain. An IP20 rating limits placement to dust-free, non-condensing environments. Visual outputs include one DisplayPort and two DVI connectors, letting the PC drive up to three independent displays, while three audio connections enable basic sound feedback or voice prompts at the HMI station. Four USB interfaces accommodate service keyboards, backup media, or barcode scanners, and a single RS-232 port maintains compatibility with legacy serial sensors or modems.

The system draws a maximum of 3 A from the AC supply, keeping cabinet power budgeting straightforward. Networking is handled by 2 Ethernet interfaces that can be assigned to real-time fieldbus or standard TCP/IP traffic, and removable storage or configuration dongles can attach through 4 USB ports. Shock loads up to 5 G for 30 ms and vibrations of 0.5 G in the 58–500 Hz range do not interrupt operation, meeting common plant-floor mechanical requirements. Continuous operation is permitted in ambient air humidity up to 95%, ensuring the PC remains functional in humid production zones where the cabinet is properly conditioned.
