Product Description:
The C6140-0080 is a control-cabinet PC from Beckhoff that belongs to the C6 Industrial PC Units series. Classified as a control-cabinet PC, it serves as the central hardware platform for TwinCAT runtime and other PLC, HMI, and data-logging tasks in automated lines. It can run machine control and visualization functions in the same enclosure, reducing the need for separate industrial computers for each task. This approach is useful in production systems where one platform must coordinate control, communications, and local visualization without relying on multiple standalone devices.
Processing is supplied by an Intel Celeron G4900 dual-core CPU clocked at 3.1 GHz, which supports deterministic cycle times for PLC tasks running under real-time extensions. The main memory consists of 4 GB DDR4 RAM, giving enough volatile space for multitasking between control, SCADA, and user interfaces. That memory capacity supports routine control logic, data logging, and interface screens running at the same time. Long-term machine recipes and log files are stored on a 1 TB 3.5-inch HDD. The chassis measures 383 x 362 x 265 mm, so it fits standard 19-inch enclosures without requiring excessive rack depth. The housing is rated IP20, which is suitable for protected control-cabinet environments and helps limit accidental contact with internal parts.
Networking is provided through 2 x 100/1000BASE-T interfaces, allowing separate connections for machine communication and plant networks without additional cards. For expansion, the backplane includes 2 PCI, 2 PCIe x1, 2 PCIe x4, 1 PCIe x16 slots so the system can accept motion, fieldbus, or graphics hardware when needed. This slot arrangement allows the PC to be adapted for motion control, fieldbus connectivity, or graphics acceleration as application needs change. Local service access is available through 4 USB 3.1 Gen. 1 ports, while DVI, DisplayPort, and RS232 connections support displays and serial devices. The assembly weighs 14 kg, which helps the chassis remain stable during cabinet mounting and machine operation.
