Product Description:

The C6930-1044-0050 is a fanless industrial PC manufactured by Beckhoff as part of the C6 Industrial PC Units series. Intended for DIN-rail mounting inside control cabinets, the unit functions as a compact control platform for PLC, motion, and visualization tasks in automated machinery. Its Intel-based architecture is combined with industrial I/O buses so the device can execute deterministic control code while interfacing directly with field modules. This model sits between the ultra-compact C6015 class and larger rack PCs, balancing computing power with cabinet depth.

The compact enclosure measures 90 × 235 × 121 mm, allowing vertical orientation beside terminal blocks without obstructing ventilation paths. A regulated input of 24 VDC feeds the motherboard through an eight-pin power connector rated at 8 A, and cable lugs up to 1.5 mm² fit directly under the screw terminals. The housing meets the IP20 protection rating, so the PC must be placed inside a sealed cabinet. Connectivity includes 4 USB ports, a single DVI-I video output, one RS-232 service port, and 2 LAN ports for EtherCAT or standard Ethernet. Internally, the board provides galvanic separation between I/O and logic domains to reduce noise coupling.

Expansion cards can be added through the backplane because the design offers 2 PCIe module slots, making it possible to mount fieldbus masters or additional network adapters without enlarging the footprint. In dynamic installations, the aluminum chassis withstands 5 G of mechanical shock for 30 ms, and the controller continues operating in ambient humidity up to 95 % RH without internal condensation. Security features include fTPM 2.0 hardware support for key storage. System mass is 2100 g, which keeps the unit suitable for DIN-rail mounting while adding stability next to nearby machinery.
