Product Description:

The C6920-1131-0050 is an industrial PC unit manufactured by Beckhoff and supplied as part of the C6 Industrial PC Units series. It is intended to serve as the central computing platform inside control cabinets, running PLC logic, visualization tasks, and data exchange services for distributed I/O and motion systems. Because an industrial PC can execute deterministic software and standard operating systems on the same hardware, this product consolidates automation, diagnostics, and networking functions that formerly required separate controllers.

The unit operates from a nominal input of 24 VDC, so it can be powered directly from common machine-level power supplies. An enclosure rating of IP20 limits use to clean, non-conductive cabinet interiors, while panel-mounted RJ-45 sockets provide 2 independent Ethernet channels for fieldbus or office networks. Front-accessible USB receptacles provide 4 peripheral connections that comply with the USB 2.0 standard, making it straightforward to attach service storage, keyboards, or barcode readers. Internal electronics tolerate ambient moisture up to 95% RH, and twin axial fans guide airflow across the 3.5-inch motherboard and expansion components to keep temperatures within rated limits.

Mechanical resilience is important for cabinet PCs mounted on moving equipment, so the chassis resists shocks of 5 G for events lasting up to 30 ms, and vibration is limited to a displacement amplitude of 0.035 mm. A single 8-pole plug carries supply voltage, ground, and remote-on contacts, reducing wiring effort. The computer presents one DVI-I port for local HMIs and a dedicated RS-232 serial interface for legacy drives or scanners. Both X102 and X103 Ethernet controllers support 10/100/1000BASE-T transmission, allowing direct connection to gigabit switches without additional adapters.
