Schneider BMXDDI6402K Discrete Input Module

The Schneider Electric BMXDDI6402K is a 64-channel discrete input module specifically designed for the Modicon M340 PAC (Programmable Automation Controller) platform. It serves as an integral component in discrete automation applications where high-density digital input processing is required. With its robust construction, fast response times, and compatibility with 24V DC source logic inputs, the BMXDDI6402K is ideal for industrial environments where reliability, modular scalability, and diagnostic capabilities are crucial.

The module is engineered to support rapid digital input acquisition from field devices such as sensors, switches, and pushbuttons. Its high-density 64-channel configuration minimizes panel space requirements, while its hot-swap capability enhances maintainability without system downtime. It interfaces easily with the rest of the Modicon M340 system via the X80 backplane, supporting plug-and-play installation and configuration through Unity Pro / EcoStruxure Control Expert.
