        Overview Manuals HART Integration Loop Power Wireless Link Applications

        Features:

        • Adds WirelessHART communication to compatible HART 5 or later field devices.
        • Operates from the 4-20 mA loop through power scavenging without a separate battery.
        • Uses a long-range integral antenna for IEC 62591 mesh networking.
        The low-copper aluminum housing of Emerson 775XD11NAWA3WK9 carries Type 4X and IP66 ingress protection for exposed industrial installations.

        Its configurable update interval lets the wireless link trade faster variable refresh for lower network traffic based on the monitoring duty.

        A direct 1/2-14 NPT connection supports instrument mounting, while the remote arrangement is used when equipment vibration exceeds the direct-mount limit.

        Apter Power provides quotation assistance and official Emerson documentation access for the Emerson 775XD11NAWA3WK9 WirelessHART THUM Adapter.

        775XD11NAWA3WK9 HART Device Integration

        • Device support: Connects to compatible two-, three- or four-wire devices using HART revision 5 or later.
        • Process data: Carries the primary variable and additional HART information into the WirelessHART network.
        • Diagnostics: Makes device status and diagnostic variables available to plant asset-management tools.
        • Wired access: Preserves the existing HART loop connection while adding a wireless communication path.

        775XD11NAWA3WK9 Loop Power Planning

        • Power source: Scavenges operating power from the connected 4–20 mA loop and does not require a battery.
        • Loop load: Requires at least 250 Ω for dependable HART communication.
        • Voltage allowance: Drops 2.25 V at 3.5 mA and 1.2 V at 25 mA during normal operation.
        • Fault margin: Reserve up to 2.5 V for the adapter when checking the loop supply under fault conditions.

        775XD11NAWA3WK9 Wireless Link Settings

        • Protocol: Communicates on a 2.4 GHz IEC 62591 WirelessHART network.
        • Update interval: Supports user-configurable update periods from 8 seconds to 60 minutes.
        • Antenna: Uses the WK9 long-range integral antenna specified by the complete ordering code.
        • Network behavior: Participates in the self-organizing WirelessHART mesh for redundant communication paths.

        775XD11NAWA3WK9 Plant Applications

        • Valve testing: Transfers valve-test results from HART-capable positioners without adding a new signal cable.
        • Asset diagnostics: Exposes device health information to maintenance and asset-management workflows.
        • Multivariable instruments: Publishes secondary HART variables that are not carried by the primary 4–20 mA signal.
        • Retrofit monitoring: Adds WirelessHART visibility to installed instruments where new wiring is impractical.
        Description
        The complete Emerson 775XD11NAWA3WK9 configuration is a Rosemount 775 WirelessHART THUM Adapter with low-copper aluminum housing, 1/2-14 NPT mounting, PlantWeb HART data functionality, NA approval, WA3 radio configuration and a WK9 long-range integral antenna.

        Connected to a compatible HART 5 or later instrument, 775XD11NAWA3WK9 transfers process variables, device status and diagnostic data into an IEC 62591 WirelessHART mesh while preserving the existing wired HART connection.

        Operating power is scavenged from the 4-20 mA loop, eliminating a separate adapter battery. The loop must retain adequate supply margin for the adapter voltage drop and at least 250 ohms of load for dependable HART signaling.

        Update periods from 8 seconds to 60 minutes let 775XD11NAWA3WK9 balance data refresh against network traffic. Its long-range antenna supports retrofit monitoring, valve-test reporting and access to additional HART variables without adding a new signal cable.

        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
        How can I verify enough loop voltage remains after installing Emerson 775XD11NAWA3WK9?
        Calculate the transmitter, wiring and load voltage requirements, then reserve up to 2.5 V for Emerson 775XD11NAWA3WK9 under fault conditions before confirming the loop supply.
        Why does Emerson 775XD11NAWA3WK9 require at least 250 Ω of loop load?
        Emerson 775XD11NAWA3WK9 uses HART signaling on the 4–20 mA loop, and a minimum 250 Ω load provides the impedance needed for reliable digital communication.
        Does Emerson 775XD11NAWA3WK9 need a separate battery?
        No. Emerson 775XD11NAWA3WK9 scavenges its operating power from the connected 4–20 mA loop, so a separate battery is not used.
        Which field devices can work with Emerson 775XD11NAWA3WK9?
        Emerson 775XD11NAWA3WK9 can be integrated with compatible two-, three- or four-wire devices that support HART revision 5 or later.
        How should I choose an update rate for Emerson 775XD11NAWA3WK9?
        Set Emerson 775XD11NAWA3WK9 between 8 seconds and 60 minutes according to how quickly the variable must change while balancing WirelessHART network traffic.
        How does the NA approval segment affect installation of Emerson 775XD11NAWA3WK9?
        The NA segment of Emerson 775XD11NAWA3WK9 means the configuration carries no hazardous-area approval. Use it only where the installation does not require classified-location certification.
        What should I do if Emerson 775XD11NAWA3WK9 is exposed to vibration above 2 g?
        Use the remote-mount arrangement for Emerson 775XD11NAWA3WK9 when vibration exceeds 2 g so the adapter is not supported directly by the field-device connection.
