ET 200SP BU30 BaseUnits

ET 200SP BU30 BaseUnits is the denser Siemens ET 200SP base-unit branch for projects that still belong in ET 200SP but need a more feature-rich or tighter cabinet-side base-unit layout than the BU15 or BU20 families. Compared with BU15 and BU20, BU30 is usually the stronger family when the installation benefits from a denser terminal concept, more segmented base-unit handling, or a higher-feature ET 200SP layout. It is usually unnecessary when the project only needs the simpler standard cabinet branch and there is no clear density or layout pressure. Keep this family in scope when the ET 200SP platform is fixed and the remaining decision is how compact or segmented the base-unit layout should be. Read the product list as a higher-density ET 200SP map first, then narrow by exact base-unit code, terminal arrangement, and module pairing.
