Schneider Electric BMXDDI3202K Discrete Input Module

The Schneider Electric BMXDDI3202K discrete input module is a 32-channel digital input block for Modicon X80 PLCs that acquires 24 V DC field signals with channel isolation (>10 MΩ) to ensure reliable signal monitoring in industrial environments. Designed for Modicon X80 platforms (M340 / M580), it provides 32 current-sink IEC Type 3 inputs with ~2.5 mA per channel, input impedance ~9.6 kΩ, and a sensor supply range of 19–30 V DC, delivering a 4 ms typical and up to 7 ms max response time with LED RUN and per-channel diagnostics for quick troubleshooting; power consumption is ~140 mA at 3.3 V DC and power dissipation ≤3.9 W, including reverse polarity protection and an external fuse per channel group, all housed in a rack-mounted IP20 module. This module is commonly used in manufacturing lines, conveyors, packaging equipment, and process control systems to monitor discrete signals from sensors, switches, and proximity devices, and it serves as a scalable option for expansion, replacement, or upgrades; common replacements include BMXDDI1602, BMXDDI6402K, and TM3DDI32.
