Siemens 6SE6400-1PB00-0AA0 Profibus DP Interface Module

Siemens 6SE6400-1PB00-0AA0 Profibus DP Interface Module is an optional PROFIBUS DP communication board for the MICROMASTER 4 series frequency converters (MM420/MM430/MM440), enabling a PROFIBUS network interface between MM4 drives and higher‑level controllers. For MM4 FX/GX variants, mechanical compatibility requires using the plug 6GK1500-0EA02. The module’s physical dimensions are 161 mm in length, 73 mm in width, and 43.5 mm in depth. It can be powered from the main drive at 6.5 V ±5% (up to 300 mA) or externally from 24 V ±10% (up to 350 mA), and provides a 5 V output (±10%, up to 100 mA) for a bus terminator or an Optical Link Plug. Catalogued as a spare part in Siemens’ MICROMASTER 4 PROFIBUS options, this module integrates with MM4 drives to support fieldbus communication within automation architectures.
