SIGNAL WORKFLOW

How X20BB27 anchors a Compact CPU station

A system view of backplane support, controller power distribution and integrated serial or CAN connectivity.

STEP 01Match the controller stack

Confirm that the CPU and power module belong to the supported Compact CPU assembly.

STEP 02Plan shared references

Account for the documented non-isolated relationship between the interfaces and backplane.

STEP 03Terminate CAN correctly

Coordinate the integrated terminating resistor with the installed CAN segment design.

CONTROL BASE PATHpower module + Compact CPU → X20BB27 backplane → RS232/CAN + X20 busThe base is part of a matched controller assembly, not a standalone communication device

USE 01Build compact machine controls

Provide the physical and electrical base for a space-efficient X20 Compact CPU station.

USE 02Connect CAN devices

Expose the controller to compatible CAN networks while using the integrated termination feature.

USE 03Link serial service equipment

Use the RS232 connection for compatible engineering or device communication functions.

USE 04Distribute station power

Carry the documented I/O supply path through the Compact CPU base assembly.

USE 05Replace damaged backplanes

Restore the correct base when the CPU and power module remain part of the verified configuration.

USE 06Standardize controller builds

Use a known Compact CPU base arrangement across repeated machine designs after compatibility review.

PURCHASING FAQ

Questions buyers ask before ordering X20BB27

Practical purchasing guidance for clearer, more confident decisions.

What does B&R X20BB27 contribute to an X20 Compact CPU assembly?

It forms the bus-module backplane and adds the documented RS232 and CAN interfaces; the CPU and CPU power module are separate components.

Does B&R X20BB27 electrically isolate its communication ports?

No. B&R states that the bus, CAN and RS232 interfaces are not electrically isolated from one another, so grounding must follow the system design.

Which applications are a good fit for B&R X20BB27?

It suits compact machine controllers that need the supported CPU base plus local serial and CAN connectivity in one assembly.

How is B&R X20BB27 supply availability handled?

The official B&R page identifies the exact module without a discontinuation notice. Current inventory, condition and lead time are confirmed at quotation.

Can B&R X20BB27 replace X20BB22 without configuration checks?

No automatic substitution should be assumed. X20BB27 adds CAN alongside RS232, so CPU compatibility, wiring, termination and the configured hardware layout must be reviewed.

What should a buyer provide for a B&R X20BB27 quote?

Send the full base label, Compact CPU and power-module numbers, required interfaces, hardware revision, quantity, condition and delivery address.
