More Information

Overview Manuals Assembly Power Path Replacement Application
  • Supports an X20 bus controller or hub base module
  • Provides the adjacent position for the supply module
  • Includes the left and right X20 end plates

X20BB80 is a B&R bus controller bus base designed for the X20 System.

The base combines a wide controller position with the adjacent supply-module position so the complete X20 fieldbus head can be assembled on the mounting rail.

Before installation or replacement, verify the complete material number, the exact bus controller or hub, matching supply module, terminal block, 24 VDC potential group, 10 A contact-load limit, included end plates, neighboring X20 slices, and station layout.

Availability, condition, price, and shipping time for X20BB80 are confirmed during quotation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is B&R X20BB80 an electronic bus controller?
No. It is the passive bus base; the compatible controller or hub and supply module are separate components.
What should be recorded before replacing B&R X20BB80?
Record the complete controller, supply module, terminal block, end plates, neighboring slices, potential groups, rail position, and wiring.
Can B&R X20BB80 be substituted with any standard X20 bus module?
No. Its wide mechanical layout is intended for a controller or hub plus supply module, so verify the exact assembly compatibility.
Why can an X20 station remain unpowered after replacing B&R X20BB80?
Check the supply module, terminal block, 24 VDC feed, fuse, potential-group path, bus contacts, rail seating, and module alignment.
Are end plates included with B&R X20BB80?
The official product page states that the left and right X20 end plates are included, but confirm the actual quoted stock contents.
What current limit matters when using B&R X20BB80?
The documented permissible contact load is 10 A; verify the complete downstream load and conductor protection.
When should B&R X20BB81 or X20BB82 be selected instead of X20BB80?
Select X20BB81 when one expansion slot is required, or X20BB82 when two expansion slots are needed for compatible X20 interface or hub add-on modules. X20BB80 is intended for installations that do not require these additional expansion slots.
