Siemens 6SE6400-1PB00-0AA0 Profibus Communication Module

Siemens 6SE6400-1PB00-0AA0 is a PROFIBUS DP communication module designed for the MICROMASTER 4 (MM4) family of inverters, enabling high‑speed fieldbus connectivity between MM4 drives and a PROFIBUS DP master. The module provides a PROFIBUS DP interface over RS‑485 with data transmission rates up to 12 Mbaud and is intended for MM4 drives such as MM420, MM430, and MM440. Its form factor is 161 mm (height) x 73 mm (width) x 43.5 mm (depth). It can be powered from the MM4 basic inverter via a 6.5 V supply (internal, up to 300 mA) or from an external 24 V supply (up to 350 mA); the module also provides a 5 V output (±10%, up to 100 mA) for bus termination or an Optical Link Plug (OLP). Operating temperature ranges from -10 °C to +50 °C (in operation) and -25 °C to +70 °C (in storage), with humidity limits per climate class 3K3 (DIN IEC 60 721-3-3). The order number for this PROFIBUS module is 6SE6400-1PB00-0AA0, and it is part of Siemens’ MICROMASTER 4 PROFIBUS options.
