Provides PROFIBUS DP master (default) and slave capability. Occupies one slot at 26 mm width, 130 mm depth. Transmission rate up to 12 Mbit/s. Cable length varies with speed — at 9.6 kbit/s up to 1 200 m, at 12 Mbit/s limited to 100 m. Factor that into your bus topology. Module draws power from the S7-400 backplane; typical loss 1 W. Provides isolated 5 V (P5ext, max 90 mA) and 24 V (max 150 mA) for the DP interface and connected slaves. No external 24 V supply needed for the module itself. Supports direct data exchange (slave-to-slave) and equidistance bus cycle. Handles up to 125 DP slaves, depending on CPU load. Lifecycle: Active — Siemens lists it as current production. No end-of-life notice. I'll quote it against your BOM line; send an RFQ for lead time.","metaTitle":"Siemens 6ES7964-2AA04-0AB0 IF964-DP, 12 Mbit/s","metaDescription":"SIMATIC S7 IF964-DP interface module for S7-400.
