        Overview Manuals Feed Protection Installation Fit Operating Limits Product Applications

        Features:

        • Controller supply: Feeds the X20 bus controller and X2X Link in the station.
        • Separate I/O input: Internal I/O power uses its own defined 24 VDC feed.
        • Service visibility: Module status and RS232 transfer have local indicators.
        The X20PS9400 is used together with an X20 bus controller as part of the station supply arrangement.

        Its controller/X2X and I/O power paths serve different loads, so the station design can account for each feed on its own terms.

        B&R specifies a suitable X20BB8x bus base and the X20TB12 terminal block as separate accessories for the installed assembly.

        Apter Power can provide quotations, technical documentation, and configuration support for the B&R X20PS9400 Isolated Bus Controller Power Supply Module.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        • BC/X2X fuse: The controller-side input has an integrated, non-replaceable fuse within the module.
        • BC/X2X polarity: Reverse-polarity protection is provided on this input, unlike the I/O feed.
        • I/O line protection: The separate I/O input requires a slow-blow line fuse rated no higher than 10 A.
        • I/O polarity: The I/O input has no reverse-polarity protection, a distinct wiring consideration for this feed.
        • Standard base: X20BB80 accommodates the bus-controller base module and the associated power-supply module.
        • One-slot expansion: X20BB81 provides one additional X20 add-on position beside the controller and supply.
        • Two-slot expansion: X20BB82 provides two add-on positions, making base choice relevant to the station layout.
        • Keyed terminal: X20TB12 is the separate 12-pin, 24 VDC keyed terminal block for this module.
        • Mounting temperature: Horizontal and vertical installation are both permitted, but vertical mounting has a lower ambient-temperature ceiling.
        • High elevation: Above 2,000 m, the permitted ambient temperature decreases by 0.5°C per 100 m.
        • Humidity: Operation is specified at 5–95% relative humidity without condensation, a boundary for cabinet conditions.
        • Module protection: IP20 is the stated protection degree, so the installation environment remains part of cabinet planning.
        • X20 controller stations: The module is used together with an X20 bus controller in the station assembly.
        • X2X Link supply: The same station module provides the controller-side X2X Link feed.
        • Internal I/O supply: It also provides the local I/O power path through its separate I/O input.
        • Redundant BC/X2X layouts: Multiple supply modules can operate simultaneously for this controller-side supply path.
        Description
        In an X20 bus-controller assembly, X20PS9400 brings the controller/X2X and internal I/O supply roles together without making them one undifferentiated feed. Their distinct inputs let the station power plan account for controller-side and I/O loads separately.

        For a station designed with more than one controller-side supply module, X20PS9400 supports parallel and redundant BC/X2X operation. This gives designers a defined option for that supply path, without implying that the separate I/O feed is also redundant.

        During fault finding, X20PS9400 reports module run/error and overload through LEDs and software, while an LED also indicates RS232 data transfer. These observations give maintenance staff a direct starting point at the power module before examining the wider station.

        Technical notes
        X20PS9400 supplies a compatible X20 bus controller, X2X Link, and internal I/O power and provides an RS232 service interface. Keep the isolated bus-controller/X2X feed separate from the non-isolated I/O feed and verify both power budgets, accessories, fuse, and redundancy plan.

        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
        When should B&R X20PS9400 be selected instead of X20PS9402?
        Choose X20PS9400 when the application needs an isolated BC/X2X feed, parallel or redundant BC/X2X operation, or the RS232 service interface.
        Can B&R X20PS9400 supply a bus controller and I/O from one module?
        Yes, but the BC/X2X and I/O feeds are distinct circuits. Verify both 24 VDC inputs, protection, loads, and isolation boundaries.
        What can cause an overload indication on B&R X20PS9400?
        Check the bus-controller and X2X load, I/O group load, downstream shorts, low input voltage, terminal mapping, and the complete station power calculation.
        Can B&R X20PS9400 modules be operated redundantly?
        Yes for the BC/X2X supply, provided the documented parallel and redundant wiring and load rules are followed.
        How is the RS232 service interface connected on B&R X20PS9400?
        It is connected through X20TB12 and supports up to 115.2 kbit/s; verify terminal assignment and remember that the interface is not isolated from the bus.
        Which mechanical accessories are needed with B&R X20PS9400?
        Use the applicable X20BB80, X20BB81, or X20BB82 bus base and an X20TB12 terminal block, ordered separately.
        What should be recorded before replacing B&R X20PS9400?
        Record both feeds, fuse, BC/X2X load, I/O load, redundancy wiring, RS232 wiring, bus base, terminal block, controller type, and diagnostics.
