Solving Multi-Rack Expansion Challenges
In complex industrial automation systems, expanding control capacity without redesigning the entire cabinet is a common engineering challenge. The Schneider TSXRKY8EX extendable rack addresses this need directly. Designed for the Modicon Premium Automation platform, this 8-slot rack enables seamless multi-rack configurations, allowing engineers to add I/O modules, specific application modules, or TSXP57 processors as production demands grow. Its robust construction and flexible mounting options make it a reliable backbone for distributed control architectures.
Technical Specifications Breakdown
The TSXRKY8EX is built with precise dimensions for efficient panel layout: 335.3 mm width, 151.5 mm height, and 160 mm depth. Weighing 3.19 lbs (1.45 kg), it is manageable for single-person installation. The rack provides 8 slots, accommodating a mix of I/O modules, TSXP57 processors, specific application modules, and TSXPSY power supplies. Electrical connectivity includes two female SUB-D 9 connectors for remote bus X connections, enabling daisy-chaining in multi-rack setups. With an IP20 protection rating, it is suitable for indoor control cabinets where dust and accidental contact are limited. The operating temperature range is 32…140 °F (0…60 °C), with storage from -13…158 °F (-25…70 °C).
Real-World Industry Applications
Manufacturing Line Expansion: In a packaging plant, adding quality inspection stations required extra I/O points. The TSXRKY8EX allowed integration of additional analog and digital modules without replacing the existing controller, saving downtime and cost.
Process Control Redundancy: For a chemical batch process, a multi-rack configuration using the TSXRKY8EX enabled separation of critical control loops from non-critical monitoring, improving system reliability and simplifying troubleshooting.
Upgrading Legacy Systems: Replacing an older fixed-rack system with the TSXRKY8EX provided flexibility to reuse existing TSXP57 processors and TSXPSY power supplies, extending the life of the automation investment.
Installation & Setup Guidance
Mount the TSXRKY8EX securely using either four M6 screws for panel mounting or clips for a 35 mm symmetrical DIN rail. Ensure the rack is installed in a clean, dry environment within the specified temperature range. Connect the remote bus X using the two female SUB-D 9 connectors, following the daisy-chain topology for multi-rack systems. Verify that all modules are firmly seated in their slots before powering up.
Maintenance & Reliability
Routine inspection of the rack includes checking for secure module seating, clean connectors, and adequate ventilation. The IP20 rating means the rack should be kept free of dust and moisture. Periodic verification of the operating temperature (0…60 °C) and humidity (10…95% non-condensing) ensures long-term reliability. Following these practices minimizes unexpected downtime and extends service life.
Compatibility & Integration
The TSXRKY8EX is designed for the Modicon Premium Automation platform. It is compatible with:
- I/O modules (discrete, analog, special function)
- TSXP57 processors
- Specific application modules (e.g., communication, motion)
- TSXPSY power supplies
This broad compatibility allows integration into existing Modicon Premium systems without additional adapters.
Buying Guide & Selection Advice
Before purchasing the TSXRKY8EX, verify your system's compatibility with the Modicon Premium platform. Confirm the required number of slots (8 available) and the need for remote bus X connectors.

Frequently Asked Questions
Can the TSXRKY8EX be used with TSX Quantum processors?
No, the TSXRKY8EX is specifically designed for the Modicon Premium platform and is compatible with TSXP57 processors, not TSX Quantum series.
What is the maximum number of racks in a multi-rack configuration?
The TSXRKY8EX supports multi-rack configurations using the two female SUB-D 9 connectors for remote bus X. The exact maximum depends on the processor and system design; refer to the Modicon Premium system manual.
Does the rack include power supply modules?
No, the TSXRKY8EX is a passive rack. It requires a separate TSXPSY power supply module to power the backplane and installed modules.
What is the weight of the TSXRKY8EX?
The rack weighs 3.19 lbs (1.45 kg) according to the manufacturer's specification.
Is the TSXRKY8EX suitable for outdoor use?
No, its IP20 protection rating means it is intended for indoor, dry, and dust-controlled environments only.
