Product Description:

The C6920-1088-0030 is a compact control computer manufactured by Beckhoff within the C6 Industrial PC Units series. It is intended to run real-time operating systems and motion libraries so that plant-level PLC logic, HMI tasks, and data exchange can be handled from a single enclosure on the factory floor. Integrated fieldbus and multimedia interfaces let the unit connect directly to drives, sensors, and supervisory networks without external gateways.

For power, an 8-pole plug delivers supply lines sized for conductors up to 1.5 mm², and the internal backplane is protected by a connector rating of 16 A to accommodate high inrush during startup. Normal operating current is limited to 0.5 A, allowing the PC to share a 24 V DC segment with other low-current devices. Two axial fans maintain component temperature, and the housing is classified as IP20, so installation is restricted to clean control cabinets. Networking is handled by two Gigabit ports that negotiate at 10/100/1000BASE-T, supporting deterministic EtherCAT traffic as well as standard IT protocols. A D-Sub-9 connector provides one RS-232 channel for legacy devices, a second D-Sub-9 serves as the dedicated CAN fieldbus interface, and visual output is provided through a single DVI-I socket for panel-mount displays.

Peripheral expansion is available through 4 x USB 2.0, so barcode readers or removable storage can be attached without a hub. The motherboard follows the 3.5-inch embedded form factor, which keeps card height low enough to fit shallow cabinets while still providing two mini-PCIe slots for I/O cards. An integrated UPS connection supplies backup power at 27 V so the operating system can perform an orderly shutdown during mains loss. Conformal-coated boards permit operation in ambient humidity up to 95%, helping protect the electronics in damp control-cabinet conditions.
