        Overview Manuals Carrier Role Network Fit Service Planning Applications

        Features:

        • Redundancy-ready base: A second EIOC can be added to the same carrier when the DeltaV and network design are prepared for a redundant pair.
        • Consolidated connections: Power entry and isolated device-network interfaces remain associated with the EIOC assembly instead of being improvised around the card.
        • Serviceable architecture: The carrier defines a stable mounting point while EIOCs and isolation ports remain separately identifiable service items.
        KL4104X1-BA1 forms the physical base of a DeltaV EIOC installation rather than performing Ethernet protocol processing itself.

        Its value is the prepared simplex-or-redundant layout: the same carrier can host the active interface and a matched standby interface.

        Selection still depends on the installed EIOC hardware, isolation-port type, power arrangement and available cabinet rail space.

        Apter Power can help confirm the Emerson KL4104X1-BA1 DeltaV EIOC Dual Horizontal Carrier, installed EIOC hardware and required isolation ports 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.
        • Stable equipment base: The carrier keeps the EIOC electronics, power entries and device-network isolation points in one repeatable cabinet location.
        • Simplex starting point: One installed EIOC can use the carrier while leaving a defined path for later redundancy.
        • Paired-card layout: Two matching EIOCs share the carrier when a redundant design is commissioned.
        • Independent processing: Protocol handling remains in the EIOC, so replacing the carrier does not change the configured device protocol by itself.
        • Isolation-port boundary: Replaceable Ethernet Isolation Ports separate the device network connection from the EIOC assembly.
        • Copper link option: The documented twisted-pair isolation port supports the standard field-network connection without changing the carrier identity.
        • Redundant path planning: A second card only improves continuity when the primary and secondary network paths are engineered correctly.
        • Control-network context: The carrier belongs to an EIOC node that connects Ethernet devices into the DeltaV control environment.
        • Label preservation: Recording the two card positions, power feeds and isolation ports prevents the redundant sides from being reversed during work.
        • Space verification: Horizontal rail clearance must be checked before staging the carrier because orientation is part of the installation design.
        • Component boundary: The carrier is a spare part; EIOCs, covers, isolation ports and power plugs are separate unless the order explicitly includes them.
        • Acceptance evidence: Card recognition, network communication and redundancy state should be verified separately after installation.
        • Ethernet-device integration: Supports Ethernet Device Networks that use the protocol configured for the EIOC, including the manufacturer-listed drive, PLC, switchgear and intelligent-device contexts.
        • Redundant interface cabinets: Provides a prepared base where loss of one EIOC should not remove the complete integration node.
        • Brownfield expansion: Adds a defined EIOC mounting point without assigning all connected Ethernet data processing to a separate controller.
        • Maintenance spares: Replaces an identified dual carrier while allowing verified EIOC and isolation-port components to remain controlled separately.
        Description
        KL4104X1-BA1 is the dual horizontal carrier for the DeltaV Ethernet I/O Card. It provides the mechanical and electrical base for one EIOC or a redundant pair, keeping power entry and isolated Ethernet connection points together in one defined assembly.

        By adding a second EIOC to KL4104X1-BA1, a prepared installation can move from simplex to redundant operation without replacing the carrier. This helps maintenance teams preserve the cabinet layout while gaining a controlled standby path for Ethernet-device integration.
        Alternative Names
        KL4104X1BA1
        Technical notes
        Confirm the installed EIOC generation, available horizontal DIN-rail space, power feed and Ethernet Isolation Ports before ordering KL4104X1-BA1. The carrier accepts one or two EIOCs, but redundancy also depends on a matched second card, correct network design and supported DeltaV configuration. Preserve the existing port and power labels during replacement.

        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
        A project has one EIOC today but may require redundancy later. Does KL4104X1-BA1 avoid replacing the mounting base?
        Yes, when the cabinet, power and network design are prepared for redundancy. The carrier can host one EIOC initially and a matched second EIOC later; software configuration and independent network paths must still be commissioned.
        The quotation for KL4104X1-BA1 includes only the carrier. Should procurement expect EIOCs and isolation ports in the package?
        No. Treat the carrier as a separate spare unless the supplier lists the cards, power plugs, protection cover and isolation ports. Request a component-by-component scope before releasing the order.
        A redundant EIOC pair reports a failed side after work on KL4104X1-BA1. Which checks should come before replacing a card?
        Verify the card seating, the corresponding power input, the assigned isolation port and the primary/secondary network path. This separates a carrier-side connection problem from an actual EIOC failure.
        The cabinet has a vertical carrier position. Can KL4104X1-BA1 be fitted because the electrical function looks similar?
        Do not proceed from electrical similarity. This item is a horizontal EIOC carrier; confirm rail orientation, clearance and the exact EIOC assembly before installation.
        A second EIOC has been inserted into KL4104X1-BA1 but DeltaV does not show a healthy redundant pair. What evidence is needed?
        Confirm that both cards are the supported matching hardware, the system recognizes their paired positions and the redundant network design is complete. Physical occupancy alone does not establish redundancy.
        An existing isolation port is damaged while KL4104X1-BA1 remains sound. Must the entire carrier be replaced?
        Not automatically. The isolation ports are replaceable components. Identify the approved port type and inspect the carrier connector before deciding whether the fault is limited to the port or includes the carrier.
