Product Description:

The C6920-1140-0060 industrial PC is manufactured by Beckhoff and belongs to the C6 Industrial PC Units series. Built for cabinet installation, the unit integrates CPU, memory, and field interfaces in one enclosure, allowing it to execute motion control, logic tasks, and HMI functions directly on the machine. By combining standard PC architecture with industrial connectors, it serves as a deterministic control platform for PLC, NC, and IoT workloads in automated production environments. This arrangement reduces the need for separate computing hardware and keeps control, visualization, and communication functions in a single cabinet-mounted platform.

Its electrical subsystem is fed from a 24 V DC supply, which aligns with common control-cabinet power rails. Incoming power passes through an 8-pole plug that can accept conductors up to 1.5 mm² and is rated for a continuous 16 A load, covering both logic consumption and peripheral current drawn through the motherboard headers. The metal housing carries an IP20 classification, permitting installation in clean, vented cabinets without additional sealing. Network traffic is handled by 2 Ethernet ports, which allows machine-level communication and supervisory links to remain separated while maintaining full-duplex data exchange.

Network cabling attaches through a RJ-45 connector that supports automatic crossover and 100/1000 Mbit negotiation. Visual output is provided by a DVI-I interface for single-cable connection to industrial monitors. Four rear I/O bays expose 4 USB ports implemented to the USB 2.0 standard, permitting connection of service keyboards, data loggers, or barcode scanners without expansion cards. Legacy point-to-point devices can use the 9-pin D-Sub carrying an RS-232 link, and a separate 9-pin D-Sub fieldbus socket is available for protocol-specific converters. Two internal fans regulate airflow across the 3.5-inch motherboard so internal hot spots are reduced during continuous-duty operation.
