BMXSRA0405 Safety Output Module | Schneider Modicon X80

Product Description

The Schneider Electric BMXSRA0405 is a safety relay output module within the Modicon X80 platform. It integrates seamlessly with Modicon M340 and M580 PLC systems for safety-related control tasks.

This module provides four electrically isolated relay outputs, allowing direct control of actuators and safety circuits. Therefore, it supports both AC and DC loads without requiring additional interface components.

Unlike transistor output modules, the BMXSRA0405 uses mechanical relay technology for higher switching flexibility. Moreover, this design allows reliable operation with inductive, resistive, and mixed industrial loads.

The module incorporates multiple protection mechanisms to support safety-critical installations. In addition, its high reliability metrics make it suitable for long-term operation in regulated industrial environments.
