Product Description

Description

Designed for direct installation inside compact control cabinets, the Beckhoff C6925-0020 industrial PC delivers robust processing capability in a passively cooled, space-saving format. This unit integrates a 3.5-inch motherboard with an Intel Celeron ULV processor to handle deterministic control tasks without the mechanical wear associated with cooling fans. Featuring a rugged aluminum housing, the Beckhoff C6925-0020 is built to withstand industrial environments while serving as an efficient control platform for TwinCAT-based applications.

Features

  • Passive Cooling Design: Fanless operation eliminates common mechanical failure points and reduces internal dust accumulation.
  • Rugged Aluminum Chassis: Compact and durable housing rated at IP20, optimized for rear-wall control cabinet mounting.
  • Flexible Expansion: Equipped with two PCIe module slots for native Beckhoff PCIe cards or custom external interface routings.
  • TwinCAT Compatibility: High performance-class classification (Class 50) optimized for real-time automation and visualization tasks.
  • Industrial Storage Interface: Features a dedicated CFast slot for reliable solid-state boot media and runtime environments.

Applications

  • Machine tool automation and local HMI control nodes.
  • Decentralized data acquisition and factory-floor IoT gateways.
  • High-vibration production environments requiring fanless computer hardware.
  • Control cabinet architectures with limited depth and mounting footprint.

Empirical Engineering Insights

Alternative Models & Compatibility

The C6925 series is a direct evolution of older Beckhoff cabinet IPC models. When replacing legacy C69xx units, ensure your current TwinCAT configuration maps correctly to the single-core Celeron architecture. For applications requiring multi-threaded tasks or heavier HMI load, verify CPU allocation limits prior to site commissioning.

Application Pitfalls & Engineering Notes

Because this controller relies entirely on passive cooling, vertical installation is mandatory to encourage natural convective airflow. Mounting the IPC horizontally or reducing the clear envelope will restrict thermal dissipation, leading to automatic processor throttling or thermal safety shutdowns when ambient enclosure temperatures exceed 50 degC.

Commissioning & Wiring Tips

Always use a stabilized 24 V DC power supply. High ripple or transient voltage spikes on the primary DC bus can trigger hardware resets. If utilizing the optional UPS expansion, ensure the capacitive or battery storage system is fully calibrated within the operating software to allow safe state saves during unexpected power dropouts.

Installation Guidelines

CRITICAL WARNING: De-energize all incoming power supplies before attempting installation, mounting modifications, or wiring connections. Failure to isolate power can result in electrical shock, hardware destruction, or erratic control states during connection phases.
1

Mount the IPC vertically on the control cabinet wall using the pre-installed rear mounting plate. Ensure at least 5 cm (2 inches) of free air space above and below the device to permit unrestrained convective cooling.

2

Connect a functional earth ground directly to the low-resistance grounding bolt located on the chassis housing to minimize EMI and protect sensitive motherboard logic.

3

Insert the pre-configured CFast card containing the operating system and runtime binaries into the dedicated flash slot before applying primary system power.

4

Connect the 24 V DC power supply lines to the power terminal plug, checking correct polarity (+ / -) prior to switching on the supply.
