PROFINET gateway for the 3RW44 soft starter
The 3RW4900-0NC00 is a SIRIUS communication module that adds PROFINET connectivity to a 3RW44 soft starter. It is designed for starters with firmware version E12 or higher — units shipped from June 2013 onward carry the required firmware level. The module fits a standard DIN-rail footprint: 111 mm deep, 36.6 mm wide, 117.3 mm high. That 36.6 mm width occupies roughly two 18 mm-wide module slots on the rail, so check the panel fill before committing the BOM line.
Lifecycle and compliance — current production, quoted to order
The substance prohibitance date is November 13, 2013, which aligns with the RoHS/REACH compliance documentation Siemens provides for this part. Expect a declaration of conformity covering the applicable EU directives at the time of manufacture.
Integration notes — firmware version and panel fit
The module mounts directly onto the 3RW44 soft starter's communication slot — no separate DIN-rail bracket needed. The 111 mm depth projects from the starter face; ensure the enclosure depth clears this plus cable bend radius for the PROFINET connector.
