Product Description:
The C6925-1004 is an ultra-compact industrial PC produced by Beckhoff within the C6 Industrial PC Units series. Designed as a DIN-rail controller, it provides central processing, fieldbus communication, and data logging for machine cells and small production lines. By combining PC-based control with standardized interfaces, the unit replaces separate PLC, HMI, and gateway hardware and simplifies system architecture in industrial automation. Its compact format suits cabinets where rail space is limited and several control functions must fit in one location.
The system accepts a 22 to 30 VDC supply and distributes power to internal logic and I/O expansion. Two Gigabit LAN sockets give the controller 2 Ethernet ports for real-time fieldbus or plant network traffic, while four front connections offer 4 USB ports for service devices or data storage. A multi-format video connector supports DVI-I so a local monitor can display process status without an additional converter. Legacy serial equipment is supported through the integrated RS232 interface. The housing has an ingress protection rating of IP20 and is intended for installation inside a closed cabinet. This mix of interfaces supports local visualization, network communication, and connection of serial peripherals from a single controller.
Reliability in factory conditions is enhanced by passive cooling, which eliminates fans that might draw dust into the electronics. Continuous operation is specified from 0 °C up to 55 °C, and functionality remains stable in relative humidity levels up to 95% without condensation. The aluminum housing endures vibration of 0.5 G at 10 Hz to 58 Hz with a 0.035 mm amplitude and survives mechanical shocks of 5 G lasting 30 ms, making the PC suitable for mounting on moving machinery. With a weight of 1.85 kg, the unit adds minimal load to control enclosures but still provides adequate thermal mass for peak processing bursts.
