Product Description:
The C6920-0070 is an industrial PC manufactured by Beckhoff within the C6 Industrial PC Units series. It is intended for DIN-rail or plate installation in electrical cabinets, where it executes real-time automation, motion, and visualization software alongside standard Windows or TwinCAT operating environments. By consolidating machine control, data acquisition, and user interface tasks into a single x86 platform, the unit streamlines panel space and reduces the number of dedicated controllers required in complex production cells.
Its housing carries a protection class of IP20, so installation is limited to clean, closed electrical enclosures. The electronics draw a nominal 24 VDC supplied through an 8-pole power connector, and peak load is limited by a connector current rating of 16 A. A compact 3.5-inch motherboard is cooled by two axial fans that maintain steady airflow over critical components. Having two fans doubles airflow paths, helping maintain silicon junction temperatures below derating limits during extended high-load cycles. Four front-side ports provide 4 × USB 2.0 connectivity for removable storage or service tools, while 2 × RJ-45 connectors expose the device to plant networks.
Visual and field communication features supplement the core interfaces. A dedicated output drives monitors through 1 × DVI-I, and the integrated controllers negotiate the 10/100/1000BASE-T standard to match network infrastructure without manual setting. For distributed I/O, a fieldbus port is available on a 9-pin SUB-D, while another SUB-D hosts the RS232 channel for service access. During handling, the aluminum chassis withstands shocks up to 5 G for 30 ms, guarding plug-in cards and cable terminations against displacement. This tolerance is important when the PC is mounted on moving gantries or transported by forklift between workstations.
