Product Description:

The C6930-0050 is an Industrial PC unit manufactured by Beckhoff within the C6 Industrial PC Units series. Designed for DIN-rail installation, it combines machine control, data processing, and fieldbus connectivity inside a 90 mm by 121 mm aluminum housing. In industrial automation, it serves as the central processor for PLC logic, motion sequences, and HMI tasks, so computing functions can be placed directly in the control cabinet near drives, I/O, and network hardware. This layout helps keep cabinet organization straightforward and supports short communication paths between the controller and connected devices.

This controller operates from a nominal supply of 24 V DC, so it can run from standard cabinet power supplies without an added converter stage. Network interfaces support 100/1000BASE-T signaling across the two onboard Ethernet ports, which supports either standard 100 Mbps communication or Gigabit networking depending on the surrounding system. Local service devices and expansion hardware connect through 4 USB ports, providing data exchange and 5 V peripheral power for common accessories. Legacy serial equipment can still be connected because the unit includes an RS232 channel on the front panel. A protection rating of IP20 means the enclosure is finger-safe and suited for use in a dry control cabinet.

The unit has a compact depth of 121 mm and a height of 235 mm, which helps it fit beside breakers, power supplies, and terminal blocks on the rail. Its mass is 2100 g, keeping the assembly light enough for cabinet mounting without adding excessive load to the support structure. For additional communication or storage functions, the motherboard provides 2 PCIe module slots, which can be used for application-specific hardware while keeping the main enclosure size unchanged. This arrangement supports flexible system layouts where one controller may need to handle both real-time automation tasks and auxiliary interface requirements.
