The TSX-LES70 is a junction or extension module (often called a “junction box” or “transition block”) designed for Schneider Electric’s Modicon TSX Micro line of programmable logic controllers (PLCs). Its primary function is to provide a convenient and secure connection point between the PLC’s controller base and additional I/O (Input/Output) expansion modules.
It is a genuine Schneider Electric product, manufactured in France, and is typically supplied new in its original box.
Key Features and Functions
- 
I/O Expansion Interface:Â Serves as a dedicated connection block for adding extra I/O modules (like digital inputs/outputs, analog modules, etc.) to a Modicon TSX Micro PLC system. It allows you to extend the capabilities of your controller beyond its local I/O capacity. 
- 
Bus Connection:Â The module contains the necessary internal bus system to seamlessly transfer data and power between the main PLC controller and the expansion modules connected to it. 
- 
Physical Mounting and Alignment:Â It features a mechanical design with guiding notches and a locking lever that ensures a secure, vibration-resistant connection between adjacent modules on the DIN rail. This “blind connection” system makes installation and maintenance quick and error-proof. 
- 
Compact and Integrated Design:Â As part of the TSX Micro platform, it is designed for a compact footprint, saving valuable space in control panels. 
- 
Status Indication:Â The module typically includes LED indicators to show the status of the bus connection and power, aiding in system diagnostics and troubleshooting.
