Telemecanique TSXRKN82F Standard Base Rack for TSX/PMX 67-40 Series PLC

The Telemecanique TSXRKN82F is a standard base rack (chassis) designed for the TSX/PMX 67-40 series programmable logic controller platform. This component serves as the mechanical mounting and electrical interconnection infrastructure for PLC systems, providing slot positions for power supply modules, CPU modules, and I/O modules. The TSXRKN82F accommodates up to eight modules, making it suitable for medium-scale automation applications requiring structured rack mounting within a control cabinet. The rack provides power distribution and backplane communication between installed modules, eliminating the need for external wiring between them.

Slot Configuration and Module Capacity

The TSXRKN82F features eight slots for PLC modules, including CPU units, power supply modules, digital I/O modules, analog I/O modules, and specialty function modules. The 8-slot configuration balances system capacity with physical footprint, supporting medium-scale applications without requiring multiple racks. Each slot includes a backplane connector that provides both power distribution and high-speed data communication between modules. The rack is compatible with TSX 47-40 series as well as TSX/PMX 67-40 systems, offering flexibility for both new deployments and expansion of existing installations. The module positions are labeled for clear identification, simplifying installation and maintenance. The rack design ensures secure module retention and reliable electrical contact under vibration typical of industrial environments.

Power Supply and Electrical Specifications

The TSXRKN82F operates on 110/220V AC power supply voltage, accommodating both North American and international industrial power standards. The power supply current rating is 2 A, providing sufficient capacity for typical configurations. An integrated AC fan provides forced-air cooling for modules mounted in the rack, maintaining appropriate operating temperatures for heat-generating components such as CPU modules and high-density I/O modules. The rack distributes power to connected modules via backplane conductors, eliminating individual power wiring to each module and simplifying system assembly. The power supply connections are made through designated terminals on the rack.

Physical Specifications and Installation

Physical dimensions of the TSXRKN82F are approximately 483 mm width, 279 mm depth, and 229 mm height, with approximate weight of 2.1 kg (4.63 lbs). Imperial dimensions are approximately 19.02 inches width, 10.99 inches depth, and 9.02 inches height. The rack is designed for mounting inside standard industrial control cabinets, with mounting points that accept bolts for secure attachment. The construction uses materials suitable for industrial environments, providing structural rigidity to support installed modules and withstand vibration. The rack dimensions are compatible with standard panel layouts, allowing integration into new or existing control cabinets. Installation requires appropriate clearance around the rack for cooling air circulation and cable routing.

Series Compatibility and System Integration

The TSXRKN82F is manufactured under the Telemecanique brand, which is incorporated into Schneider Electrics automation product portfolio. This rack is required for building Modicon TSX/PMX 67-40 control systems, providing the physical and electrical infrastructure that ensures connectivity and operational performance. The integrated backplane supports high-speed communication between modules, enabling coordinated control without external wiring between them. The rack also provides consistent mounting dimensions, allowing simplified panel layout and reduced engineering time for system integration. The rack is intended for use with compatible TSX series power supply modules, CPU modules, and I/O modules from the same product family.

Cooling System Design

The integrated AC fan provides forced-air cooling for installed modules, dissipating heat generated during operation. The fan draws ambient air through the rack enclosure, passing it over modules to maintain appropriate operating temperatures. The fan is designed for continuous operation and is replaceable for maintenance purposes. Airflow direction and clearance requirements are specified in the installation documentation. The cooling system contributes to reliability by maintaining module temperatures within specified ranges, especially for high-density I/O configurations or when the rack is installed in warm environments. Periodic inspection of the fan for dust accumulation and proper operation is recommended as part of a maintenance program for the control system.

Legacy System Support and Applications

The TSXRKN82F is part of the TSX series of programmable logic controllers, a legacy platform that remains in service in many industrial facilities. The rack is used in systems where the original control equipment remains operational and replacement with newer technology has not been implemented. Typical applications include manufacturing lines, packaging machinery, material handling systems, building automation, and process control skids. The rack is a component for maintenance and repair of existing installations, as well as for expansion of systems where additional modules must be added to an existing rack.

Conclusion

The Telemecanique TSXRKN82F standard base rack provides an 8-slot mounting platform for TSX/PMX 67-40 series PLC modules. With 110/220V AC power supply, integrated AC fan cooling, and compatibility with TSX series components, this rack supports legacy automation installations requiring structured module mounting and backplane communication.
