Product Description:

The C6920-1108-0050 is an industrial PC manufactured by Beckhoff for the C6 Industrial PC Units series. Designed for DIN-rail or plate mounting inside cabinets, it acts as the central computing platform that executes PLC logic, motion control, and visualization in automated equipment. By embedding multi-protocol Ethernet and legacy fieldbus interfaces in one housing, the unit connects field I/O, drives, and supervisory servers, creating a unified control layer for machine builders and process plants.

The wiring terminal accepts conductors up to 1.5 mm², and airflow is maintained by 2 cooling fans that draw heat away from the 3.5-inch mainboard. Two gigabit adapters specified as 2 x 10/100/1000BASE-T provide deterministic EtherCAT and standard TCP/IP communication, while the fieldbus interface is delivered through 1 x 9-pin D-Sub for devices that still rely on serial bus protocols. An internal fuse rated at 16 A protects the 8-pin power connector during inrush or wiring faults. Additional I/O includes one RS-232 service port, four USB 2.0 sockets for removable media or HMI panels, and a DVI-I output for high-resolution operator screens. The housing has an IP20 rating, and the status circuit draws only 0.5 A so uninterruptible supplies can monitor system health without excessive load.

Environmental and reliability data guide cabinet layout and transport limits. Continuous operation is allowed up to 95% RH non-condensing, and the electronics withstand mechanical shocks of 5 G, 30 ms during shipping or line stoppages. When paired with the matching Beckhoff UPS module, the DC link provides backup power at 27 V to perform a controlled shutdown. Despite the communication and cooling hardware, the enclosure weighs only 1.9 kg, so it can be clipped onto standard rails without added reinforcement.
