        • Provides the bus base for standard-width 240 VAC X20 I/O modules
        • Interconnects the internal I/O supply across the potential group
        • Uses coordinated 240 V coding for the bus, electronic, and terminal modules

        X20BM12 is a B&R 240 vac bus module designed for the X20 System.

        The module supports the electronic module and terminal block, preserves the 240 V coding relationship, and continues the internal I/O supply to adjacent compatible slices.

        Before installation or replacement, verify the complete material number, 240 VAC keying, electronic-module and terminal-block compatibility, potential-group boundary, 10 A contact-load limit, isolation and protective devices, neighboring bus modules, and station layout.

        Availability, condition, price, and shipping time for X20BM12 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.
        VIEW ALL FAQS
        Can B&R X20BM12 be substituted for a 24 VDC bus module?
        No. X20BM12 is 240 VAC keyed and must be used only with the officially compatible electronic module and terminal block.
        Does B&R X20BM12 create a new potential group?
        No. Its internal I/O supply is connected through. Use the documented supply-bus arrangement when an electrical group must be interrupted or newly fed.
        Why is keying important when ordering B&R X20BM12?
        The bus module, electronic module, and terminal block use coordinated 240 V coding, so a visually similar 24 VDC component is not an acceptable replacement.
        What should be checked if a 240 VAC slice on B&R X20BM12 does not operate?
        Remove power and verify the upstream supply, protective device, terminal block, electronic module, keying, bus contacts, potential-group continuity, and controller diagnostics.
        Is the 24 VDC value in B&R X20BM12 data the external 240 VAC field circuit rating?
        No. The official I/O-supply table lists a 24 VDC nominal internal supply, while the module keying and compatible slice type are for 240 VAC equipment; keep these functions distinct.
        How should the contact-load limit of B&R X20BM12 be checked?
        Calculate the current carried through the relevant bus contacts for the complete compatible group and keep it within the documented 10 A limit.
        What should be documented before replacing B&R X20BM12?
        Record the exact slice position, compatible electronic and terminal modules, 240 V keying, potential-group boundaries, upstream protection, wiring, and station power calculation.
