Product overview

General properties of the BaseUnits
In the ET 200SP distributed I/O system, there are a number of different BaseUnits. The
BaseUnit determines, among other things, the process connection, the suitable I/O
modules/motor starters, and the infeed of the supply voltage. All properties can be identified
by the short designation of the BaseUnit which is explained below.
