Product Overview

The BMXDDI1602 (Model: BMXDDI1602) is a high-performance discrete input interface engineered for the Schneider Electric Modicon M340 and M580 (X80) automation platforms. This module provides 16 isolated digital input channels, specifically designed to capture binary signals from industrial field devices such as limit switches, pushbuttons, and proximity sensors.

Operating as a current sink (positive logic) module, the BMXDDI1602 (Part Number: BMXDDI1602) is optimized for use with sourcing (PNP) sensors. Its compact form factor is essential for space-constrained control cabinets, while its robust isolation and diagnostic visibility ensure deterministic signal acquisition in electrically noisy industrial environments. The module facilitates seamless integration within the X80 backplane architecture, maintaining high system reliability and simplified maintenance.
