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.
