Schneider BMXSAI0410 Safety Analog Input Module

Overview

The Schneider Electric BMXSAI0410 is a safety analog input module from the Modicon X80 series, designed for high-integrity process safety applications. It provides four isolated 4–20 mA inputs, ensuring accurate and secure signal acquisition for SIL3-certified safety systems. The module supports CIP Safety communication, features current out-of-range detection, and includes TÜV Rheinland certification for compliance with IEC 61508 standards. This module is ideal for Modicon M580 Safety systems, supporting both local and remote rack installations. It uses a 20-way removable terminal block for easy wiring and is identifiable by its red safety coating. With high-resolution 16-bit conversion, internal recalibration, and robust environmental resistance, the BMXSAI0410 delivers reliable performance in demanding industrial safety environments.
