Siemens 6ES7964-2AA04-0AB0 Programmable Logic Controller Module

Siemens 6ES7964-2AA04-0AB0 is the IF964-DP interface module that functions as a PROFIBUS DP master for the SIMATIC S7-400 family, connecting the CPU to DP devices on the field bus. It features an isolated PROFIBUS DP master interface with a maximum transmission rate of 12 Mbit/s and supports up to 125 DP devices, providing 244 bytes of user data per DP device for inputs and outputs. Physical dimensions are 26 mm wide, 54 mm high, and 130 mm deep, with a weight of about 65 g and a typical power loss of 1 W. The DP interface can supply up to 150 mA to connected devices; the module itself draws no current from a 24 V supply, delivering 24 V at the DP interface.
