The Siemens 6ES7972-0BA11-0XA0 Profibus DP interface module is a SIMATIC DP bus connector that provides a PROFIBUS DP interface for connecting Siemens field devices to a PROFIBUS network at speeds up to 12 Mbit/s. It uses a 9-pin SUB-D connection and a 90-degree cable outlet, with compact dimensions of 15.8 mm (W) x 54 mm (H) x 34 mm (D), and is supplied without a PG socket connector. An integrated termination resistor with a disconnect function accommodates proper line termination when used as the last device on the bus.
