The physical module intercepts 4-20 mA DC input loops and derives a proportional 0-10 VDC voltage output for registration by high-impedance monitoring nodes. Operating with passive and active electronic filtering topologies, the 2-wire hardware design achieves galvanic signal separation without requiring auxiliary operational power bus lines.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eN0309YK (2AI-P2V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eFoxboro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.11 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Foxboro inline transmitter card footprint\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 to +80 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eDependent on current loop draw (low power configuration)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003e0-10 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e\\pm 0.1% of configured span\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelectable Input\/Output Spans\u003c\/td\u003e\n\u003ctd\u003e0-100 mV, 0-200 mV, 0-500 mV, 0-1000 mV, 0-2000 mV, 0-4000 mV, 0-5000 mV, 0-10000 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e24 VDC nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eFully isolated input to output circuit architecture\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Protection\u003c\/td\u003e\n\u003ctd\u003eIntegrated reverse polarity protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation and HART Loop Protocol Interaction\u003c\/h3\u003e\n\u003cp\u003eThe transceiver layout introduces continuous channel-to-channel isolation matrices across the conversion pathway. This electrical barrier prevents field-induced common-mode currents from altering internal amplifier bias references, preserving a linear transfer function across the entire operating spectrum. While transforming the base 4-20 mA DC current level, the internal active input impedance profile maintains a high-frequency characteristics match with the 4-20 mA HART loop protocol layer. This compatibility passes smart telemetry frequencies unimpeded across the isolation barrier, enabling simultaneous analog scaling and digital data routing to centralized supervisory hardware.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the converter behave if the 4-20 mA current input drops below the standard 4 mA threshold?\u003c\/p\u003e\n\u003cp\u003eA: The internal processing circuits maintain linear down-scaling down to the lower saturation limit. A total loop break (0 mA) causes the internal logic to drop the output signal voltage to 0 VDC, triggering an out-of-range flag on the supervising PLC or DCS analog input card.\u003c\/p\u003e\n\u003cp\u003eQ: Is manual calibration required to maintain the specified \\pm 0.1% of span accuracy across the full operational temperature range?\u003c\/p\u003e\n\u003cp\u003eA: No, the component employs internal temperature compensation networks to mitigate thermal drift across the -40 to +80 deg C span. Factory calibration remains valid provided the input supply voltage remains stabilized at 24 VDC.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding and Shield Separation\u003c\/strong\u003e: Connect the field instrumentation cable drain wire to a single, dedicated earth point inside the local termination marshalling junction box. Do not ground the shield at both ends, as this will violate the channel-to-channel isolation boundary and cause measuring drift.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpan Selection and Wiring Terminals\u003c\/strong\u003e: Prior to applying loop power, configure the terminal links to match the designated input\/output span configuration. Ensure all point-to-point connections use gas-tight crimp lugs to minimize loop resistance variations on the input terminals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConduit and Signal Separation\u003c\/strong\u003e: Route the low-voltage 0-10 VDC output lines in dedicated wire trays physically isolated from parallel 440 VAC power distribution cables or variable frequency drive conductors to prevent inductive noise injection.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":43461753733210,"sku":"N0309YK","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/416_6fe8a70b-ff17-43e8-94f4-97fa51815aee.jpg?v=1780882757","url":"https:\/\/www.spareoil.com\/products\/n0309yk-foxboro-2ai-p2v-signal-converter-technical-datasheet","provider":"SpareOil Automation","version":"1.0","type":"link"}
