It mounts specifically on the SIRIUS 3RA19 22-1A standard rail adapter, so the mechanical integration path is locked to that adapter plate — no direct DIN-rail clip, no alternative mounting bracket. ## Functional role in the AS-Interface network This module provides mechanical and electrical support for an AS-Interface load feeder module — it's the carrier and bus interface for the feeder, not a standalone I/O slice. The 45 mm width matches the standard mounting rail plate footprint used across the SIRIUS 3RA19 family, so panel cutouts and wiring ducts stay consistent. ## Lifecycle and sourcing posture Listed at current lifecycle stage — Siemens has not flagged this for discontinuation, so it remains a valid BOM line for new builds and MRO spares alike.","metaTitle":"Siemens 3RK1901-3GA00 AS-Interface Support Module, 45mm","metaDescription":"Siemens 3RK1901-3GA00 AS-Interface support module, 45mm wide, for SIRIUS 3RA19 standard rail adapter.
