Schneider Electric TBX discrete input module with a documented system role and explicit evidence boundaries.

Documented function

Rebuilt from individual evidence

System position

Unknown: Evidence boundary

Schneider Electric identifies TBXEEP1622 as a Modicon Premium TBX discrete input module with 16 positive 24 V DC inputs.

The exact datasheet records IP65 protection and Fipio compatibility for TBXEEP1622.

The module sits between 24 V field sensors or switches and the Modicon Premium PLC over the Fipio distributed-I/O path.

Unknown: The installed PLC, sensor wiring, address configuration, line lengths, and site-specific compatibility are not established by the captured sources.
