Product Precautions
B&R 7EX290.50-1 is system 2003 x2x link bus controller. It connects System 2003 I/O to an electrically isolated X2X Link network.
- Provides one X2X Link interface
- Uses a 24 V DC supply
- Electrically isolates the expansion link
- Connects a System 2003 station to X2X
7EX290.50-1 operates with System 2003 rack, separate terminal block, X2X Link cable, upstream B&R controller.
Engineered applications include System 2003 remote I/O, X2X migration interface, Electrically isolated expansion link, Bus-controller replacement.
Important Notice: Record X2X node and rack identities, match the separately ordered terminal block and verify all remote I/O after controlled startup.

System 2003 remote I/O
Extends legacy System 2003 I/O over X2X.
X2X migration interface
Interfaces old and current B&R architectures.
Electrically isolated expansion link
Separates remote-station communication electrically.
Bus-controller replacement
Restores the expansion node without changing rack addressing.
Read the applicable B&R instructions before work. Verify 7EX290.50-1 and the installed B&R System 2003 expansion configuration.
1
Verify the full 7EX290.50-1 marking and its assigned B&R System 2003 expansion position before work.
2
Place the connected machine or process in the approved maintenance state.
3
Isolate the applicable supply and electrically isolated x2x link process data field energy before disconnecting conductors.
4
Record connector, conductor, address and software identities before removal.
5
Use ESD controls and protect keyed interfaces, exposed contacts and electronic assemblies.
6
Confirm the installed System 2003 rack and separate terminal block against the approved project.
7
Restore power in a controlled sequence and review device, network and host diagnostics.
8
Prove the intended system 2003 remote i/o function and retain the final test result.
Technical notes
Record X2X node and rack identities, match the separately ordered terminal block and verify all remote I/O after controlled startup.
