Siemens 6ES7964-2AA04-0AB0 IF964-DP Interface Module

Siemens SIMATIC S7-400 IF964-DP Interface Module, MLFB 6ES7964-2AA04-0AB0, is a PROFIBUS DP master interface for the SIMATIC S7-400 family. As the DP Master for S7-400, it enables communication with PROFIBUS DP I/O devices by linking distributed I/O blocks to the S7-400 CPU over the PROFIBUS DP network. The module is designed for DIN-rail mounting in S7-400 racks and draws about 150 mA from the S7-400 backplane. The PROFIBUS DP network connected through IF964-DP supports cable distances up to 100 m at 12 Mbps and up to 1,200 m at 9.6 kbps, enabling scalable deployment of remote I/O across industrial facilities. Typical applications include integrating distributed I/O modules, sensors, and actuators into a Siemens automation architecture, providing centralized control and straightforward diagnostics via the S7-400 programming environment. The IF964-DP interface module forms a standard part of the SIMATIC S7-400 lineup, delivering DP Master functionality that partners with DP slaves and other PROFIBUS DP devices while maintaining compatibility with Siemens engineering tools and project data.
