BMXDDM16025 Modicon X80 mixed digital I/O module

Schneider Electric X80 mixed I/O module with eight 24 V DC inputs and eight relay outputs.

System role

Rebuilt from individual evidence

Schneider Electric identifies BMXDDM16025 as a Modicon X80 mixed digital I/O module with eight 24 V DC inputs and eight relay outputs.

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

The module collects eight digital field states and switches eight relay-controlled field circuits under controller command.

System role

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

Function
The module receives eight digital inputs and switches eight relay outputs.
System position
It sits between field sensors or contacts, the Modicon controller and relay-driven loads.
Upstream / inputs
24 V DC field signals enter the input channels and controller commands arrive through the rack bus.
Downstream / outputs
The module reports input states and switches its relay outputs toward downstream loads.
Limitations
Unknown: the relay load wiring, input configuration, protection and condition of an individual module.
