Schneider Electric BMXDDI6402K Discrete Input Module

The BMXDDI6402K is a Modicon X80 discrete input module that provides 64 isolated 24 V DC inputs (current sink, logic positive) suitable for connecting proximity sensors and other digital devices. It uses two 40-pin connectors for all channels and requires a sensor power supply of 19–30 V DC; per-channel input impedance is around 40 kΩ, with a total module power dissipation of about 4.3 W. The unit is IP20 protected, operates from 0 to 60°C, and includes external fuse protection (one 0.5 A fast-blow fuse per group) plus status LEDs for RUN, ERR, and channel diagnostics. As part of the Modicon X80 family, BMXDDI6402K delivers isolated inputs, supports 19–30 V sensor power, and offers a typical DC response time around 4 ms (7 ms max) with MTBF around 510,000 hours.
