The Original New Schneider Electric BMXDDI3202K is a 32-channel discrete input module for the Modicon X80 I/O platform, designed to acquire digital signals from field devices in industrial automation applications. It provides 32 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 supports 2-wire/3-wire proximity sensors and conforms to IEC 60947-5-2 and IEC 61131-2 Type 1 standards.
