        More Information

        Overview Manuals Segment Design Terminal Fit Service Limits Applications

        Features:

        • Four H1 segment ports: One module presents four separately identifiable fieldbus connections to the DeltaV I/O position.
        • Defined power boundary: LocalBus demand and per-port fieldbus supply are stated independently for cabinet and segment planning.
        • Keyed field interface: The D2 terminal setting distinguishes this function from other DeltaV I/O circuits.
        KC3030X1-BA1 is the electronic interface between DeltaV LocalBus electronics and four FOUNDATION Fieldbus H1 segments.

        Its most important service distinction is the four-port layout combined with D2 terminal keying and a separate field-power requirement.

        The module is replaced as a complete unit; segment wiring, power and communication are tested outside the enclosure rather than by internal adjustment.

        Apter Power can help identify the Emerson KC3030X1-BA1 DeltaV Fieldbus H1 4-Port Plus Interface and its D2 terminal arrangement before quotation.

        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.
        • Four-port architecture: Each H1 segment retains a distinct physical port for commissioning and fault isolation.
        • Shared control interface: The module brings the four segment paths into one DeltaV I/O position without merging their field wiring.
        • Power separation: LocalBus consumption does not replace the required fieldbus supply at the ports.
        • Commissioning sequence: Segment voltage and communication are established one port at a time before the complete module is released.
        • D2 key position: The terminal block must match the documented key setting before the card is seated.
        • Port identity: Field conductors remain associated with their recorded H1 port during replacement.
        • Carrier relationship: Bussed field power can reach the module through the carrier and must be included in isolation planning.
        • Wrong-function barrier: Correct rotary keying helps prevent an unrelated I/O card from meeting the established field circuit.
        • De-energized handling: Both field and system power are removed before connection or removal.
        • Complete-unit service: Internal disassembly is outside the permitted user-service scope.
        • No calibration step: Return-to-service checks focus on voltage, segment communication and device status.
        • Classified-area procedure: Product marking and the referenced DeltaV Zone 2 method govern the destination installation.
        • H1 instrument networks: Connects compatible FOUNDATION Fieldbus transmitters and final elements to DeltaV.
        • Multi-segment cabinets: Organizes four fieldbus trunks at one identified I/O position.
        • Segment fault isolation: Separate ports let maintenance distinguish a single wiring path from a module-wide problem.
        • Brownfield replacement: Restores an exact D2-keyed position while preserving verified segment assignments.
        Description
        KC3030X1-BA1 connects four FOUNDATION Fieldbus H1 ports to a DeltaV I/O position. Each port receives the documented fieldbus supply range while the module communicates through the LocalBus, giving cabinet designers one defined boundary between controller-side electronics and four field segments.

        The keyed terminal relationship and hazardous-area instructions make KC3030X1-BA1 a controlled replacement rather than a generic four-port coupler. A successful exchange depends on removing both field and system power, preserving the D2 key position, and returning each segment to its recorded port.
        Alternative Names
        KC3030X1BA1
        Technical notes
        Remove field power and system power before inserting or removing KC3030X1-BA1. Its terminal block uses key position D2, and each H1 port has a defined supply boundary. The module has no user-serviceable parts and needs no calibration, so troubleshoot segment power, wiring and the keyed terminal before replacing or opening the unit.

        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
        All four H1 segments disappeared after work on KC3030X1-BA1. Which common points should be tested first?
        Start with module seating, LocalBus power, shared field-power delivery and the keyed terminal connection. A common supply or carrier interruption can remove all four segments while their field devices remain healthy.
        Only one port on KC3030X1-BA1 has lost its field devices. Does that indicate a failed module?
        Not necessarily. Measure the fieldbus supply at that port and inspect its trunk, terminators and connected devices before condemning the module. Healthy communication on the other ports narrows the fault boundary.
        Can KC3030X1-BA1 be removed while the DeltaV controller remains energized?
        No. Emerson states that the unit cannot be inserted or removed with system power energized, and field power supplied at the terminal or through the carrier must also be removed.
        A spare resembles KC3030X1-BA1 but uses another terminal key. Is it suitable for a temporary test?
        Do not bypass the keying boundary. The replacement must match the complete model and D2 key position so the existing H1 field circuit is not connected to a different I/O function.
        Does a replacement KC3030X1-BA1 need bench calibration before commissioning?
        No module calibration is required. Commissioning should prove fieldbus voltage and communication on every affected port and confirm that the expected devices return to DeltaV.
        Receiving obtained KC3030X1-BA1 without the terminal block or fieldbus power accessories. Is the order complete?
        Only if the quotation intentionally covers the electronic module alone. Compare the supplied scope with the installed carrier, D2-keyed terminal and field-power arrangement before accepting it for the outage.
