Description
The TSXRKY8EX is an 8-slot rugged expansion rack base designed for the Schneider Electric Modicon Premium automation platform. This chassis facilitates the physical and logical scaling of PLC systems by providing a stable backplane for high-density I/O and communication modules. It is engineered for demanding industrial environments, including chemical processing, petroleum refining, and power generation, ensuring reliable signal integrity and reduced system downtime.
Features
- Supports up to 8 standard Modicon Premium functional modules.
- Integrated passive backplane with high-speed bus communication.
- Dedicated 9-pin female connector for TSXBusX high-speed network extension.
- Onboard rotary hex switch for rack address configuration.
- Robust metallic chassis with integrated M6 copper grounding studs for enhanced EMC.
- Flexible mounting options including direct panel screw fixation or 35 mm DIN rail.
Applications
This expansion rack is suitable for distributed I/O architectures in large-scale automation systems. It is commonly deployed in thermal power stations, mining extraction grids, and complex manufacturing lines where modular scalability and high-availability communication are critical.

Installation Guidelines
- Ensure the rack is mounted on a flat, vibration-resistant surface or a properly secured 35 mm DIN rail.
- Always power down the system before installing or removing any modules from the rack slots.
- Connect the M6 grounding studs to a low-impedance earth ground to minimize electromagnetic interference.
- Maintain proper ventilation clearance around the rack to ensure operating temperatures remain within the 0 to 60 deg C range.
- Verify the rotary address switch is set correctly for the specific rack segment before powering up the bus.
FAQ
Can this rack be used as a standalone base? No, the TSXRKY8EX is designed as an extension rack base and requires connection to a primary processor rack or another upstream expansion chassis via the TSXBusX link.
How many expansion racks can I add? The system architecture supports up to 3 expansion bases per segment.
