BMXDDI6402K 64-Channel Discrete Input Module 24V DC Positive | Schneider Electric

The Original New Schneider Electric BMXDDI6402K is a 64-channel discrete input module for the Modicon X80 I/O platform, designed to acquire digital signals from field devices in high-density industrial automation applications. It provides 64 isolated inputs with positive (sink) logic for 24V DC signals. Part of the common I/O platform for Modicon M340 and M580 Programmable Automation Controllers (PACs), this module reduces maintenance and training costs with compatible modules and unique training for different Programmable Automation Controllers (PACs).

Core Engineering Highlights:
64 isolated discrete inputs (positive logic/sink) | 24V DC | 1 mA nominal input current | 4 ms typical response time (7 ms max) | 40 kΩ input impedance | 1500V AC isolation (channels to bus) | 510,000 hours MTBF | 4.3 W power dissipation | IP20 protection | 0°C to +60°C operating temperature | Two 40-way FCN connectors
