C6525-1009-0040 by Beckhoff

The C6525-1009-0040 is an industrial PC manufactured by Beckhoff as part of the C6 Industrial PC Units series. Intended for cabinet installation, the computer provides centralized control, human-machine interface functions, and data logging for automated machinery through its integrated communication and display interfaces. Its PC-based architecture supports deterministic task scheduling and high-level software execution in applications that might otherwise require separate control and computing hardware. The compact design also allows processing and visualization functions to operate from a single cabinet-mounted unit.

The housing measures 330 × 275 × 82 mm, allowing it to fit in shallow control enclosures while preserving space for field wiring. The electronics operate from a 22-30 VDC supply protected by an internal 16 A fuse, allowing direct connection to common 24 V utility rails. Network connections are provided through two 100/1000BASE-T Ethernet ports, which support real-time fieldbus communication or standard TCP/IP traffic. The front panel includes four USB 2.0 ports for keyboards, removable storage devices, barcode readers, and other compatible peripherals. An anodized enclosure with IP65 protection permits operation at ambient temperatures from 0 °C to 45 °C. When installed inside a closed cabinet, the unit has IP20 protection and can operate at temperatures up to 55 °C. A single RS-232 serial port supports legacy equipment, while a DVI video output provides a connection for a local display.

The computer withstands shocks of 5 G for 30 ms, supporting installation in machine frames exposed to intermittent mechanical impacts. Its vibration endurance is rated at 10-58 Hz at 0.035 mm, with the upper frequency range continuing to 500 Hz at 0.5 G. Non-operating storage is permitted from -20 to +65 °C, allowing the unit to remain in unconditioned storage areas when it is not in service. The industrial PC has an overall mass of 4.74 kg, which must be considered when selecting cabinet supports and mounting hardware. Prewired spring terminals accept conductors with cross-sectional areas up to 1.5 mm² for power and signal connections.
