Product Description:

The C6650-0020 is an industrial PC unit produced by Beckhoff within the C6 Industrial PC Units series. Designed for cabinet installation, the system hosts control software that coordinates drives, I/O modules, and visualization tasks in automated machinery and process cells. Acting as an open-architecture computing node, it enables deterministic real-time control alongside standard operating systems, linking factory networks with field devices through expansion cards and integrated interfaces. This arrangement allows the PC to serve as a centralized platform for machine logic, communications, and operator-interface functions.

The front panel carries a protection rating of IP20, which limits dust ingress and requires placement inside a sealed control enclosure. System scalability is provided by 7 slots that accept PCI or PCIe boards up to 210 mm long, allowing motion controllers or fieldbus masters to be installed without exceeding card limits. For peripheral connection, the chassis presents 4 USB ports that follow the USB 2.0 standard. It also includes a 1 x 10/100 Mbit RJ-45 Fast Ethernet interface, plus legacy connections such as one RS-232 serial port, an LPT1 parallel port, two PS/2 inputs, and a 15-pin VGA socket. Mic, line-in, and line-out audio jacks support local acoustic signaling, while two removable drive frames simplify hard disk exchange.

Mechanical dimensions aid cabinet layout: the height is 360 mm, the width is 410 mm, and the depth is 201 mm. With a mass of 12 kg, the unit can be placed on standard 19-inch shelves before it is secured in place. The steel housing keeps internal cards aligned during vibration, and dedicated airflow paths accommodate a full complement of expansion boards. The rack-mounted form also leaves room for rear cable routing and supports orderly placement inside enclosed control cabinets.
