C6920-1047-0030 by Beckhoff

The C6920-1047-0030 is an industrial PC produced by Beckhoff as part of the C6 Industrial PC Units series. Intended for control-cabinet mounting, the unit serves as the central processing platform for machine sequencing, visualization, and deterministic network communication inside automated production cells. By combining x86 computing hardware with integrated cooling and industrial connectors, it enables continuous operation in environments that demand reliable data handling and direct field connectivity.

Power for the system is provided through an 8-pole plug that accepts a nominal input of 24 VDC. The mating screw terminals accommodate the specified 1.5 mm² conductors and connect to an internal distribution rail sized for typical control loads. Two axial fans force air across the embedded motherboard and ancillary cards to maintain component temperature under load. Networking is handled by 2 × RJ-45 10/100/1000BASE-T ports for simultaneous machine-network and enterprise connections. Local expansion and maintenance tools can be attached through 4 × USB 2.0 receptacles on the front panel. A 9-pin D-Sub connector provides a fieldbus gateway, and a second 9-pin D-Sub connector offers a dedicated RS-232 service channel. For visualization, the controller provides 1 × DVI-I interface for digital or analog monitors.

With a protection classification of IP20, the enclosure is intended for clean rooms or cabinet locations where dust and moisture are controlled. Continuous operation is permitted at ambient temperatures up to 55 °C, and the electronics remain stable at relative humidity levels reaching 95% without condensation. During transport or storage, the device tolerates temperatures from -25 °C to 65 °C, protecting the circuit boards and the 3.5 in form-factor motherboard from thermal stress. The internal power distribution and connector set support a peak load of 16 A, providing adequate capacity for attached drives, I/O modules, and panel backlights that may be supplied from the same rail.
