Beckhoff C6925-1009 fanless C6 industrial PC

Evidence-backed reference for a Beckhoff fanless C6 industrial PC used in cabinet automation.

Documented system function and position

Rebuilt from individual evidence

Wake Industrial identifies C6925-1009 as a Beckhoff C6 Industrial PC with an Intel Atom processor, fanless cooling to 55 C, and a 24 VDC supply.

The listing reports two independent Ethernet interfaces, TwinCAT compatibility, and two free PCIe module slots.

The industrial PC is positioned in a control cabinet between automation software and connected machine interfaces.

Unknown: Exact CPU variant, installed cards, firmware, unit condition, and machine compatibility require separate verification.
