The BMXDDI3202K is a 32-channel digital input module from the Schneider Electric Modicon X80 series. It interfaces 24V DC field signals with controllers such as the Modicon M580 and Modicon M340.
Configured for Positive (Source) logic, the module is optimized for high-density industrial applications requiring reliable signal acquisition. It supports both 2-wire and 3-wire proximity sensors and includes channel status LEDs plus RUN/ERR diagnostics for quick troubleshooting.
Built-in reverse polarity protection and support for external fast-blow fuses enhance field-side protection and system reliability.

Q1: Which connector is required?
The module uses a 40-pin HE10 (MIL) connector, commonly paired with BMXFCC053 cordsets or Telefast terminal bases for simplified wiring.
Q2: How does it handle voltage drops?
An internal threshold detector monitors field voltage. If supply drops below 14V DC, the module flags a sensor fault to prevent invalid signal processing.
