BMXDDI6402K Modicon X80 64-input digital module

Schneider Electric X80 module for 64 positive-logic 24 V DC digital inputs.

System role

Rebuilt from individual evidence

Schneider Electric identifies BMXDDI6402K as a Modicon X80 discrete input module with 64 positive-logic 24 V DC inputs.

The manufacturer product page documents the module's X80 range, 0-60 degrees C operating range and IP20 protection.

The module receives binary field states and presents them to the Modicon controller as digital input data.

System role

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

Function
The module receives 64 positive-logic 24 V DC field states.
System position
It sits between field contacts or sensors and the Modicon controller input image.
Upstream / inputs
24 V DC signals from field contacts or sensors enter the 64 input channels.
Downstream / outputs
The module reports the resulting digital states to the Modicon controller.
Limitations
Unknown: the sensor wiring, fuse arrangement, input configuration and condition of an individual module.
