C6525-1013-0050 by Beckhoff

The C6525-1013-0050 is a fanless industrial PC produced by Beckhoff and supplied within the C6 Industrial PC Units series. It is intended for control-cabinet mounting in automated machinery where a compact Windows-based controller must operate directly on the plant floor. By combining a processor, fieldbus interfaces, and local data storage in one housing, the unit acts as the central execution platform for PLC logic, HMI tasks, and machine-level networking.

The enclosure measures 330 × 275 × 82 mm, providing enough board area for add-on cards while still fitting shallow cabinets. Its dual housing has an IP65 / IP20 rating, which protects the electronics from dust and low-pressure water jets while allowing internal modules to receive convection cooling. The system has a mass of 4.74 kg, helping limit vibration loads on mounting rails. Networking is handled by 2 Ethernet ports that support the 100/1000BASE-T standard for soft real-time EtherCAT or conventional TCP/IP traffic. Removable media and service tools connect through 4 USB ports that comply with the USB 2.0 standard, and an RS-232 interface supports legacy drives or barcode scanners. A DVI output connects operator panels with resolutions up to Full HD. An eight-pin supply connector routes the 24 V input and internal UPS wiring; steady logic consumption is 0.5 A, while the UPS output can deliver 2.0 A to buffer field devices during brownouts.

Primary overcurrent protection is provided by a 16 A fuse located in the power-entry stage. Incoming conductors with cross-sectional areas of up to 1.5 mm² can be terminated without ferrules. The aluminum chassis withstands shocks of 5 G for 30 ms, supporting transport on factory carts and forklifts. Operation is permitted at relative humidity levels of up to 95% without condensation. This humidity tolerance allows the controller to operate in washdown zones or high-moisture packaging lines without separate climate conditioning.
