Description

The BECKHOFF CX2550-0020 is a dedicated storage extension module designed for integration with CX20xx series Embedded PCs. This module provides an accessible, physical slot to accommodate and interface a standard 2.5-inch SATA hard disk drive (HDD) or solid-state drive (SSD) directly into the modular controller assembly.

By connecting directly to the system bus of a CX20xx CPU, the BECKHOFF CX2550-0020 provides localized high-capacity storage capability. This architecture is particularly suitable for data-intensive automation tasks, local database management, operating system hosting, and extensive historical data logging at the machine level.

Power is drawn internally through the system bus, utilizing the connected CX2100-0xxx series power supply modules. This eliminates the need for auxiliary external power cabling and maintains a clean, compact footprint within the control cabinet.

Features

• Compatible with standard 2.5-inch SATA storage media (both HDD and SSD).
• Direct system bus connection to the CX20xx Embedded PC CPU.
• Internal power distribution through the CX2100-0xxx power supply module system bus.
• Robust IP20-rated enclosure designed for standard DIN rail multi-module mounting.
• SATA connection technology for reliable data transmission speeds.

Applications

• High-capacity data logging and trend recording in industrial PC systems.
• Local hosting of execution databases and enterprise-level telemetry buffers.
• Extended storage configuration for operating system backups and local recovery files.

Installation Guidelines

1. De-energize the System: Ensure all power to the CX20xx Embedded PC and connected CX2100-0xxx power supply modules is completely disconnected before installation.
2. Assemble the Module: Align the system bus connector of the CX2550-0020 with the adjacent CX20xx CPU module or other existing extension modules on the DIN rail.
3. Mechanical Connection: Snap the module securely onto the DIN rail, ensuring the locking mechanisms are fully engaged and electrical contact is made across the system bus.
4. Drive Integration: Insert the 2.5-inch HDD or SSD into the slot before final system power-up. Secure the drive in place as designated by standard housing fasteners.
5. Shielding & Grounding: Confirm that the DIN rail itself is properly grounded to ensure proper EMC performance as specified by EN 61000-6-2.
6. Commissioning: Apply power to the system and verify drive detection in the BIOS/UEFI or target operating system environment.

Replacement Recommendations

When replacing a BECKHOFF CX2550-0020 module, always perform a complete backup of the data residing on the installed HDD or SSD. Power down the system entirely before removing the drive or detaching the extension module from the main controller assembly. Re-insert the existing storage drive into the replacement module to preserve system configuration, license, and partition tables.
