Structural Design and Layout
The TSXRKY8 non-extendable rack provides a sturdy mounting platform for Modicon TSX Micro and Premium PLC components. This backplane offers eight physical slots, allocating one position for the power supply module and seven remaining slots for I/O modules, communication adapters, or specialty function cards. The rack employs Schneider Electric’s X-Bus technology, which facilitates high-speed data exchange at 2.5 Mbps between all installed modules. Consequently, this design ensures synchronous operation and minimal communication latency across the entire system.
Physical Characteristics
Measuring 130 mm in height, 312 mm in width, and 135 mm in depth, the TSXRKY8 fits comfortably into standard 19-inch cabinets or DIN-rail enclosures. Weighing 1.8 kg, this rack features robust steel construction that resists vibration and mechanical stress commonly found in industrial settings. The passive backplane design dissipates only 2.5 W of heat, contributing to lower overall cabinet temperatures and improved system longevity.
Power Distribution Capabilities
This rack distributes up to 3.0 A at 5 VDC from the installed power supply to all connected modules. Each slot receives regulated power through the backplane traces, ensuring stable operation even when all slots house high-current modules. Users must calculate total current consumption of their selected modules and verify it remains within the 3.0 A limit to avoid overloading the backplane.
Installation and Mounting
Mount the TSXRKY8 securely onto a flat panel or DIN rail using the provided mounting holes and hardware. Install the power supply module in the leftmost slot, then populate the remaining seven slots with I/O and specialty modules as required. The rack automatically establishes X-Bus communication upon power-up, requiring no manual addressing or configuration steps. For maintenance, simply remove any module from its slot without powering down the entire rack, as the design supports hot-swapping for most compatible components.
