C6525-1021-0050 by Beckhoff

The C6525-1021-0050 is an industrial personal computer manufactured by Beckhoff within the C6 Industrial PC Units series. It serves as a compact control node that runs motion, logic, and visualization tasks directly in automated production lines. Designed for cabinet mounting, the system uses fanless cooling and solid-state components, supporting continuous operation in environments where equipment is exposed to vibration, electromagnetic noise, and elevated ambient temperatures. Its architecture combines PC-class processing with industrial connectors so users can consolidate HMI, fieldbus master, and data management functions on a single platform.

The front panel provides one DVI interface for a local monitor and two Ethernet ports that use the gigabit-capable 100/1000BASE-T physical layer. The primary network interface uses an Intel i210 controller connected through the high-bandwidth PCIe bus, providing deterministic data transfer for real-time field protocols. A second port is routed through the chipset link, creating an independent path for plant supervisory traffic. Video, storage, and networking loads are isolated so control cycles remain predictable. Input power is supplied at 24 VDC, allowing the PC to connect directly to common control-voltage rails without an external converter.

Peripheral expansion is provided through four USB ports that operate according to the USB 2.0 standard, making them suitable for memory sticks, service keyboards, or low-speed cameras. Legacy devices are supported by a single RS-232 line presented on a 9-pin D-Sub connector, simplifying integration with scales or barcode readers. The secondary network interface uses an Intel i219 controller integrated into the chipset, providing another connection without occupying an expansion slot. Protective grounding is completed through a grounding stud, which provides a secure connection to the cabinet's protective earth system. An eight-pole power plug carries the incoming supply together with remote-on contacts, simplifying cabinet wiring and external power control.
