Siemens ET 200SP BaseUnits

Siemens ET 200SP BaseUnits is the baseline series for narrowing standard cabinet-mounted ET 200SP base-unit choices before selecting an exact order code. Use it when the project already points to ET 200SP, but terminal arrangement, potential-group layout, and spare strategy still need to be stabilized at the series layer. Compare it against shielded and high-feature variants when shielding requirements, denser terminations, or more segmented layouts could change the shortlist.
