  • Provides twelve push-in field terminals
  • Supports tool-free insertion and lever-assisted release
  • Offers marking, test access, and customer coding

X20TB12 is a B&R 12-pin push-in terminal block designed for the X20 System.

The terminal block connects a larger terminal set to a compatible X20 electronic module while keeping field wiring removable from the I/O slice.

Before installation or replacement, verify the complete material number, twelve-pin terminal assignment, compatible electronic and bus modules, conductor material and cross-section, stripping length, ferrules, voltage and current limits, customer coding, and quoted-stock contents.

Availability, condition, price, and shipping time for X20TB12 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.
How do I confirm that B&R X20TB12 matches an electronic module?
Use the exact electronic-module product page or manual and compare the required terminal block, keying, and terminal assignment before ordering.
Can B&R X20TB12 replace X20TB06?
Only if the electronic module explicitly supports X20TB12 and the twelve-pin terminal map is followed; pin count and wiring layout are not interchangeable by assumption.
Why can a conductor pull out of B&R X20TB12?
Check strip length, conductor size, ferrule type, strand damage, complete insertion, and whether the lever was left actuated.
Can aluminum conductors be connected to B&R X20TB12?
No. The official specification permits copper conductors only.
Is B&R X20TB12 supplied with power-supply modules?
Do not assume it is included. B&R commonly lists X20TB12 as a mandatory accessory ordered separately, so verify the quoted contents.
How should field wiring be preserved when replacing B&R X20TB12?
De-energize the circuit, photograph and label every conductor, preserve polarity and commons, and compare the complete wire schedule before reconnection.
What checks matter before energizing B&R X20TB12?
Confirm the exact module terminal map, voltage, current per contact, copper conductor and ferrule sizes, strip length, retention, coding, and module seating.
