Description
Beckhoff C6925-1004 Industrial PC
Product Introduction
The Beckhoff C6925-1004 is a legacy C6-series industrial PC designed for control-cabinet installation in industrial automation systems. Unlike a compact PLC controller, the C6925-1004 provides a general-purpose industrial computing platform for applications requiring local operating-system-based processing, machine control software, visualization, data handling, or other PC-based automation functions. The documented configuration uses a 333/400 MHz-class processor, 1 GB of RAM, and an 80 GB storage device. Current component records identify the exact C6925-1004 as discontinued by Beckhoff.
The Beckhoff C6925-1004 uses a 24 VDC supply and is specified at approximately 35 W power consumption. Its fanless control-cabinet design eliminates a rotating cooling fan, while the documented operating range is 0 to +55 °C and the enclosure protection rating is IP20. These characteristics place the unit within the older generation of Beckhoff industrial PCs intended for protected control-panel environments rather than exposed field installation.
For replacement work, the Beckhoff C6925-1004 should be matched as a complete hardware/software platform rather than simply as a computer with equivalent CPU performance. The installed operating system, storage contents, automation software, network configuration, connected Beckhoff hardware, display arrangement, and machine-specific application can all affect interchangeability. Current records also show related C6925 variants with different hardware and power configurations, so the full part number should remain the primary procurement reference.

The 24 VDC, 35 W, 1 GB, 80 GB, 0 to +55 °C, and IP20 specifications are specifically reported for .
A separate -0000 listing describes a related configuration with an Intel Atom processor, two independent Ethernet interfaces, PCIe expansion, and newer Windows IoT capability. Because this differs materially from tgacy specification above, those features should not be automatically attributed to xact part number.
C6925-1004
Main Features and Engineering Considerations
Fanless Control-Cabinet Design
The is specified as a fanless industrial PC. This removes a mechanical fan from the cooling arrangement, which is useful in control cabinets where dust accumulation and fan wear are maintenance concerns. The tradeoff is that cabinet ambient temperature and heat dissipation become important installation factors.
Legacy Industrial Computing Platform
The 333/400 MHz processor, 1 GB memory, and 80 GB storage identify this as an older PC architecture. It should not be evaluated using modern industrial-PC performance expectations. The important issue in a running machine is compatibility with the installed automation software and operating environment.
24 VDC Industrial Power
The is specified for 24 VDC operation with approximately 35 W power consumption. When replacing the unit, verify the cabinet power supply capacity and wiring polarity. Do not assume that eC6925-series variant has the same power requirement; related models can have substantially different configurations.
IP20 Protection
IP20 indicates that this is equipment intended for installation inside a suitable protected enclosure. It is not a field-mount device intended to withstand direct exposure to water, oil, or dust. Cabinet environmental conditions therefore remain part of the installation specification.
Storage Is a Major Replacement Issue
The 80 GB storage device can contain the operating system, automation application, configuration files, drivers, and machine-specific data. Replacing the physical computer without preserving this environment can result in a hardware installation that powers up but does not reproduce the original machine-control environment.
Part-Number Discipline
Beckhoff used multiple configurations. Current records li003, , -1006, -1009, -1010, and other variants. The complete identifier should therefore be retained in procurement and maintenance documentation.
Application Scenarios
- Beckhoff-based industrial automation systems
- Control-cabinet PC applications
- Machine-tool control systems
- PC-based machine automation
- Industrial visualization and HMI applications
- Legacy production-machine maintenance
- Replacement of older Beckhoff C6-series industrial PCs
- Automation system refurbishment
Engineer’s Guide: Field Pitfalls
Do not assume every is equivalent. variants can have different processor, storage, power, and interface configurations.
Do not copy specificatfrom -onto . The available records show materially different configurations between these identifiers.
Preserve the original storage environment. Before replacement, determine what operating system, automation software, drivers, licenses, and machine-specific configuration are stored on the 80 GB device.
Check cabinet temperature. The documented operating range is 0 to +55 °C. Cabinet internal temperature, not the ambient temperature outside the enclosure, is the relevant figure for the installed computer.
Check the 24 VDC supply. Confirm voltage, polarity, fuse protection, and available power before connecting a replacement.
Check discontinued status. Current recordstify as discontinued. This makes condition, storage media, and functional testing especially important when purchasing maintenance stock.
Verify network hardware separately. Do not infer a particular EtherCAT, Ethernet, or fieldbus interface from the family name alone. The exact hardware configuration and installed expansion hardware should be checked on the unit.
Frequently Asked Questions
What ishoff ?
It is a C6-series industrial PC designed for control-cabinet installation in industrial automation applications.
What voldoes use?
The dnted specification is 24 VDC.
How much power does it consume?
xact is listed at approximately 35 W.
What are the memory and storage specifications?
The documented configuration has 1 GB of RAM and an 80 GB storage device.
Is fanless?
Yes. It is identified as a fanless control-cabinet industrial PC.
What is the operating temperature?
The documented range is 0 to +55 °C.
What is the protection rating?
The is listed as IP20.
Is discontinued?
Yes. Current component records identify as discontinued by the manufacturer.
Can -0000 be used as a direct replacement?
Do not assume so. The able -0000 documentation describes a materially different configuration, including an Intel Atom processor and different expansion/connectivity characteristics. The exact machine application, software environment, and hardware configuration should be checked before substitution.
Procurement Note
For maintenance purchasing, specify exactly and request photographs of the nameplate, connectors, storage device, and expansion hardware. Because the part is documented as discontinued, a used or refurbished unit should be functionally tested rather than accepted based solely on a successful power-on test.
The most important acceptance checks are 24 VDC operation, storage-device condition, installed software/environment, memory configuration, processor identification, network interfaces, cabinet mounting compatibility, and operation under the intended temperature conditions.
