Overview
The BaseUnits (BU) are classified according to different types. Every BaseUnit type is
distinguished by characteristics that match certain I/O modules and motor starters (see the
following table and graphics).
You recognize the BU type for an I/O module by the last two digits of an I/O module's article
number.
Note
You will find a complete overview of the possibilities of combining BaseUnits and I/O
modules
/motor starters in the Product information for documentation of the ET 200SP I/O
system (
