BMXDDO6402K Modicon X80 64-channel digital output module

Schneider Electric X80 module for 64 positive-logic 24 V DC transistor outputs.

System role

Rebuilt from individual evidence

Schneider Electric identifies BMXDDO6402K as a Modicon X80 discrete output module with 64 positive-logic 24 V DC transistor outputs.

The Schneider Electric data sheet documents 0.1 A per output, 1.2 ms output response and protection against reverse polarity, short circuit, overload and overvoltage.

The module converts controller output commands into protected 24 V DC switching signals for field loads.

System role

This section explains what the product does and where it acts in the surrounding system.

Function
The module switches 64 positive-logic 24 V DC transistor outputs.
System position
It sits between the Modicon controller output image and downstream DC field loads.
Upstream / inputs
The controller sends digital output commands through the Modicon rack bus.
Downstream / outputs
The module switches protected 24 V DC signals toward field actuators and indicators.
Limitations
Unknown: the load wiring, external fuses, output configuration and condition of an individual module.

    • www.se.com — retrieved 2026-09-12; high confidence

  • The Schneider Electric data sheet documents 0.1 A per output, 1.2 ms output response and protection against reverse polarity, short circuit, overload and overvoltage.

    Confidence: high

Inferences

  • The module converts controller output commands into protected 24 V DC switching signals for field loads.

    Confidence: medium

    Rationale: The documented product function and interfaces establish its position between the named upstream and downstream system stages.

Unknowns

  • Unknown: the load wiring, external fuses, output configuration and condition of an individual module.

    Confidence: low

    Missing evidence: The captured sources do not inspect the individual unit or its installation configuration.
