Description
The Siemens 6ES7972-0BB12-0XA0 is a SIMATIC DP bus connector: the 9-pin sub-D plug that joins a PROFIBUS DP station to the RS 485 bus cable. It takes the incoming and outgoing bus cable on screw terminals, has a 90° (right-angle) cable outlet, and has a programming (PG) socket on the back. A slide switch brings in the integrated terminating resistor; Siemens specifies it with an isolating function, so switching the resistor on at the end of a segment disconnects the outgoing cable. Siemens rates it for 9.6 kbit/s to 12 Mbit/s, IP20, and gives its size as 15.8 x 64 x 35.6 mm (W x H x D).
Application: PROFIBUS DP networks
Used with: PROFIBUS DP stations with a 9-pin sub-D interface
What is the 6ES7972-0BB12-0XA0 used for?
It plugs into the PROFIBUS DP port of each station on the bus: PLC CPUs and communication modules, distributed I/O, drives and operator panels. Every station needs one; the first and last connector on a segment have the terminating resistor switched on. The PG socket on the back lets a programming device or diagnostics tool be plugged in without breaking the bus.

Product Questions
Is the 6ES7972-0BB12-0XA0 discontinued?
No. Its manufacturer lifecycle status is Active.
Can another Siemens SIMATIC DP PROFIBUS connectors part replace it?
Potential replacements must be checked against the required ratings, dimensions and connections. Sharing a family name does not establish interchangeability.
Do you ship worldwide?
Yes. TimControls ships worldwide. Parts usually ship within 3 to 7 working days of order confirmation, and the exact lead time and shipping options are stated on your quote. Include your delivery country and postal code when you ask for a quote.
