USE 01

Seat the Compact CPU

The base provides the documented mounting and backplane position for every B&R X20 Compact CPU.

USE 02

Receive the CPU power module

The adjacent Compact CPU power supply module is installed on the same base assembly and ordered separately.

USE 03

Expose an RS232 channel

The integrated serial connection supports machine-level service or peripheral communication defined by the controller project.

USE 04

Carry the I/O supply path

The base routes the nominal 24 VDC I/O supply with the permissible contact load stated by B&R.

USE 05

Complete the station edges

Left and right X20 end cover plates are supplied with the module for a finished Compact CPU assembly.

USE 06

Support cabinet integration

Horizontal and vertical mounting options allow the base to fit documented X20 cabinet arrangements within the temperature limits.

PURCHASING QUESTIONS

B&R X20BB22 buyer FAQ

Clear purchasing answers for system matching, replacement and documentation decisions.

Which controller assemblies can use B&R X20BB22?

B&R identifies X20BB22 as the base for all X20 Compact CPUs. The exact CPU and its separately ordered Compact CPU power supply module must still be matched before installation.

What wiring issue matters most when integrating B&R X20BB22?

The X20 bus and RS232 interface are not electrically isolated, so cabinet grounding, cable routing and the serial-device reference potential must be reviewed together.

When should an engineer choose B&R X20BB22 instead of X20BB27?

Choose X20BB22 when the Compact CPU assembly needs the documented RS232 base only. X20BB27 is a different official version that adds CAN and an integrated CAN terminating resistor, so it is not an automatic drop-in substitution.

Is B&R X20BB22 discontinued, and can it still be quoted?

B&R currently maintains an official product page, data sheet and hardware-upgrade downloads for X20BB22 without a published discontinuation notice. Stock, condition and revision are confirmed during quotation.

What must be checked before replacing a B&R X20BB22 base?

Verify the installed Compact CPU, CPU power supply module, RS232 wiring, end-cover arrangement, hardware revision, Automation Studio project and environmental approval requirements before replacement.

Which documents and order details help with a B&R X20BB22 inquiry?

Request the official X20BB22 data sheet and X20 System User's Manual, then provide the base label, Compact CPU and power-module numbers, hardware revision, quantity, condition and delivery destination.

PEOPLE BEHIND THE WORK

Professional Team

Experience, careful verification and patient communication support demanding automation purchases.

Professional automation sales and support team at work — Team development, product review and customer support during our 2017 growth stage.

EXPERIENCE

Nearly 10 Years of Industry Experience

Our team members have an average of more than 10 years of industry experience.

Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.

JUDGMENT

Professional Product Judgment

We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.

SERVICE

Sincere and Patient Service

Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.

In Practice — Indian discontinued control module

An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.

In Practice — German mixed-product inquiry

A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.
