- 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.
