Schneider TSXASZ401

Product Overview

The Schneider TSXASZ401 is a high-performance safety relay module from Schneider Electric’s Modicon TSX Premium automation system series. It is designed for industrial safety control applications, ensuring compliance with international safety standards (e.g., ISO 13849-1, IEC 62061) in critical scenarios such as emergency stop (E-Stop), safety door monitoring, and light curtain protection.

The TSXASZ401 features a dual-channel safety architecture, supporting Safety Integrity Level (SIL 3) and Performance Level (PL e) for high-reliability industrial environments. It can detect faults in safety circuits (e.g., welded contacts, short circuits, wire breaks) and immediately cut off power in hazardous situations to protect personnel and equipment.

With a compact design, the module integrates seamlessly into the Modicon TSX Premium PLC system and supports various safety inputs (e.g., safety contacts, sensors) and outputs (safety relay contacts).

2. Key Features
