What this rack does in an ET 200pro line
The 6ES7194-4GD20-0AA0: This is the SIMATIC DP module rack compact, broad version — the mechanical backbone that carries I/O modules and motor starters in an ET 200pro distributed I/O island. It is sold by the meter, so you cut and configure the length to match the exact number of modules on the drop. The rack belongs to the Accessories for ET 200pro motor starters family, meaning it is designed to accept the ET 200pro motor starter modules alongside standard I/O slices in the same assembly. At 2000 mm as shipped, the rack supports a substantial module count — plan the layout against the module widths to avoid leaving unused rail or needing a splice.
Lifecycle and compliance for BOM planning
Export control is straightforward: AL N / ECCN N, so no special licensing is needed for cross-border shipments to most destinations.
Sourcing and ordering this rack
As a standard stock item (product class A), this rack is available through Siemens distribution and can be returned within the standard returns period if unopened. For production quantities, we quote against your BOM line — confirm the required length and we will source the exact meter count. The rack ships as one piece in packaging measuring 2000 x 240 x 45 mm — factor this into kitting and freight planning, especially if ordering multiple units.
