Electric Modicon X80 Digital Input Module | Schneider BMXSDI1602

Product Description

The Schneider Electric BMXSDI1602 is a discrete input module from the Modicon X80 platform. It is designed for reliable signal acquisition within Modicon M340 and M580 PLC systems.

This module provides sixteen non-isolated digital inputs operating at 24 V DC positive logic. Therefore, it supports direct connection of standard industrial sensors and switching devices.

The BMXSDI1602 accepts signals from two-wire and three-wire proximity sensors compliant with IEC 60947-5-2. Moreover, integrated diagnostics improve transparency during commissioning and routine operation.

Thanks to fast response times and stable current thresholds, this module ensures accurate detection of field signals. In addition, its compact X80 format simplifies system expansion without increasing cabinet complexity.
