Schneider TSXRKY8EX Extendable Rack for Modicon Premium Automation

Product Overview

When building a distributed control system, you need a reliable backplane that scales with your process. The Schneider TSXRKY8EX extendable rack provides exactly that—a robust foundation for Modicon Premium automation platforms. Designed for multi-rack configurations, this 8-slot rack accepts I/O modules, TSXP57 processors, specific application modules, and TSXPSY power supplies. Its IP20 protection rating suits controlled industrial environments where dust and accidental contact are limited. For maintenance engineers, the TSXRKY8EX simplifies system expansion and module replacement without disturbing existing wiring.

Technical Specifications

The TSXRKY8EX measures 335.3 mm wide, 151.5 mm high, and 160 mm deep. It weighs 1.78 kg (3.92 lb US), making it manageable during installation. The rack operates from 0 to 60 °C (32 to 140 °F) and stores from -25 to 70 °C (-13 to 158 °F). Relative humidity ranges from 10 to 95% without condensation during operation and 5 to 95% without condensation during storage. It functions at altitudes up to 2000 m (6561.68 ft). Two female SUB-D 9 connectors provide remote connection of bus X for multi-rack linking. The rack mounts via four M6 screws on a panel or clips onto a 35 mm symmetrical DIN rail. Pollution degree 2 applies, and protective treatment TC is included.

Industry Applications

This rack excels in manufacturing lines, material handling, and process control where modular I/O distribution is critical. For example, in a packaging line, the TSXRKY8EX hosts analog input modules for temperature sensors and digital output modules for actuators, all coordinated by a TSXP57 processor. Its multi-rack capability lets you place I/O near field devices, reducing cable runs and simplifying troubleshooting. Maintenance engineers appreciate the hot-swappable module design—replace a faulty I/O card without powering down the entire system, minimizing downtime.

Installation & Setup Guidance

Mount the TSXRKY8EX on a panel using four M6 screws or snap it onto a 35 mm DIN rail. Ensure the rack is level and securely fastened to prevent vibration. Connect bus X cables using the two female SUB-D 9 connectors for multi-rack expansion. Verify that the ambient temperature stays within 0 to 60 °C and relative humidity below 95% without condensation. For reliable operation, keep the IP20 enclosure closed during service and avoid exposing the rack to conductive dust or moisture.

Maintenance & Reliability

Periodically inspect the TSXRKY8EX for loose connections, dust accumulation, and signs of corrosion. Clean the exterior with a dry, lint-free cloth—do not use solvents. Check that all module latches are fully engaged. The rack's CE marking and compliance with IEC 61131-2 ensure it meets industrial standards. Storage in a controlled environment between -25 and 70 °C preserves long-term functionality. By following these simple steps, you extend service life and reduce unexpected failures.

Compatibility & Integration

The TSXRKY8EX is designed for the Modicon Premium automation platform. It works seamlessly with I/O modules, TSXP57 processors, specific application modules, and TSXPSY power supplies. For multi-rack configurations, connect racks via the bus X using the two female SUB-D 9 connectors. The rack also complies with CSA C22.2 No 142 and UL 508, making it suitable for North American installations. Always verify module compatibility with your system revision before ordering.

Buying Guide & Purchasing Advice

Before purchasing the TSXRKY8EX, confirm your required slot count—this rack offers 8 slots. Check that your existing modules match the Modicon Premium form factor. For multi-rack systems, ensure you have the correct bus X cables and connectors. BluePLC Industrial stocks this rack and can advise on compatible accessories.
