TSXLES20 (Part Number: TSXLES20) is a serial communication expansion module for the Modicon TSX Micro PLC. It provides two additional independent serial ports, allowing simultaneous data exchange with HMIs, drives, or other controllers. This offloads communication tasks, keeping the PLC processor free for control operations.
The module fits a compact half-slot format and supports multiple protocols, making it ideal for networked industrial systems without upgrading to a larger PLC family.
