6ES7972-0BA12-0XA0 PROFIBUS RS485 Bus Connector

A 90-degree screw-terminal connector for attaching PROFIBUS stations to an RS485 bus cable.

Product Summary

Siemens 6ES7972-0BA12-0XA0 is a SIMATIC DP PROFIBUS bus connector for linking compatible stations to an RS485 PROFIBUS cable. This version uses screw connections, a 90-degree cable outlet and a 9-pin Sub-D station interface. An integrated terminating resistor can be switched through an isolating function, while the connector is supplied without a PG programming socket. It suits planned control-cabinet assembly, field-network maintenance and like-for-like procurement where the exact suffix and mechanical orientation matter. Before ordering, confirm the complete article number, cable specification, station interface, transfer-rate requirement, installation clearance and label details.

Functions and Construction

Technical Data Summary

Installation and Wiring

1. Isolate the relevant network segment and follow the equipment documentation before wiring.
2. Confirm conductor preparation and screw-terminal requirements for the selected PROFIBUS cable.
3. Maintain cable shielding, strain relief and the specified 90-degree outlet orientation.
4. Set the integrated terminating resistor according to the connector position in the bus segment.
5. Check the 9-pin Sub-D station interface and mounting clearance before commissioning.

Applications

• Connecting compatible PROFIBUS DP stations to an RS485 bus cable.
• Control-cabinet PROFIBUS wiring with a 90-degree cable exit.
• Maintenance replacement of the same complete connector configuration.
• Bus-segment endpoints that require selectable integrated termination.
• Network commissioning after cable and interface verification.

Compatibility and Revision Notice

The complete suffix is essential. Before purchasing 6ES7972-0BA12-0XA0, compare the original nameplate and connector markings with the required configuration.

Confirm the PROFIBUS segment length and transfer rate, cable construction, 9-pin Sub-D interface, screw-connection requirements, 90-degree outlet clearance, terminating-resistor position, station hardware or firmware requirements, installation dimensions and photos of the original device label.
