Product Description

The TSXLES20 is a local rack expansion communication module developed by Schneider Electric for the Modicon TSX Series automation architecture. This module enables high-speed local backplane communication between a primary CPU rack and additional I/O expansion racks, allowing multiple racks to function as a single unified control system.

The TSXLES20 is designed for applications requiring high I/O density without transitioning to network-based remote I/O architectures. It is commonly used in compact machine control systems where deterministic communication speed is critical for process sequencing and machine synchronization.

Technical Specifications

Parameter Specification
Model Number TSXLES20
Module Type Local I/O Expansion / Control Module
Communication Interface Proprietary Local Bus Extension
Expansion Distance Short-range (typically same cabinet)
Bus Current Consumption 250 mA – 400 mA
Mounting Style Standard TSX PLC slot mount
Diagnostics LED indicators for power and bus status
Protocol Type Hardware-level transparent backplane communication

Application

The TSXLES20 is commonly deployed in:

  • Motor control centers (MCC)

  • Packaging machinery control systems

  • Water and wastewater treatment automation

  • Legacy TSX system expansions

It allows engineers to increase control point density while maintaining low-latency deterministic communication between racks.

Technical FAQ

Does the TSXLES20 require special cabling?
Yes. It must be paired with TSXCBY series local bus extension cables to maintain proper shielding and signal integrity between racks.

Can this module be used for remote I/O expansion?
No. The TSXLES20 is strictly designed for local rack expansion. For longer distances, network-based or remote I/O solutions are required.
