BMXDDI1602 16-Channel Discrete Input Module 24V DC Sink | Schneider Electric

The Original New Schneider Electric BMXDDI1602 is a 16-channel discrete input module for the Modicon X80 I/O platform, designed to acquire digital signals from field devices in industrial automation systems. It provides 16 isolated inputs with positive logic (sink configuration) for 24V DC signals, supporting 2-wire and 3-wire proximity sensors per IEC 60947-5-2 and IEC 61131-2 Type 3 standards. Part of the common I/O platform for Modicon M340 and M580 Programmable Automation Controllers (PACs), this module offers a 4 ms typical response time, 6.8 kΩ input impedance, and reverse polarity protection with external fuses per group. It is supplied with a 20‑way removable terminal block.

Core Engineering Highlights:
16 isolated discrete inputs (sink/positive logic) | 24V DC | 3.5 mA typical input current | 6.8 kΩ input impedance | 4 ms typical response time (7 ms max) | Reverse polarity protection + 0.5A fuse per group | 2.5 W power dissipation | 738,749 hours MTBF | IP20 protection | 0°C to +60°C operating temperature | 20‑way removable terminal block
