The unit accepts digital inputs from dry contact switches or 24 VDC field sensors to provide near real-time state detection across industrial process loops. It converts field binary state changes into internal logic values with a fast data refresh cycle of approximately 10 milliseconds.\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\u003eNFDV161-P00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.75 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard STARDOM module footprint\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e24 VDC internal logic power\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e16 discrete input channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Type\u003c\/td\u003e\n\u003ctd\u003e24 VDC \/ Dry contact inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003eApproximately 10 kOhm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Refresh Cycle\u003c\/td\u003e\n\u003ctd\u003eApproximately 10 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Type\u003c\/td\u003e\n\u003ctd\u003eOptocoupler galvanic isolation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Compatibility\u003c\/td\u003e\n\u003ctd\u003eSinking and sourcing input configurations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlatform System\u003c\/td\u003e\n\u003ctd\u003eYokogawa STARDOM Controllers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol and Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe Yokogawa NFDV161-P00 incorporates optocoupler galvanic isolation between individual channels, as well as between field input circuits and system logic power. This isolation structure suppresses high-voltage field noise, transients, and ground potential differences from affecting internal controller backplanes or parallel 4-20 mA HART instrumentation loops. High channel impedance of approximately 10 kOhm minimizes signal loading on connected field switches while accommodating both sinking and sourcing field configurations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What input devices can be connected to the Yokogawa NFDV161-P00 module?\u003c\/p\u003e\n\u003cp\u003eA: The module accepts discrete inputs from potential-free dry contact switches as well as field sensors providing standard 24 VDC output signals.\u003c\/p\u003e\n\u003cp\u003eQ: What is the signal refresh time for the input channels on the NFDV161-P00?\u003c\/p\u003e\n\u003cp\u003eA: The module features a fast internal data update cycle of approximately 10 milliseconds for real-time state acquisition.\u003c\/p\u003e\n\u003cp\u003eQ: Does the module support both sinking and sourcing field wiring configurations?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the input conditioning architecture supports both sinking and sourcing digital signal connections.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDisconnect backplane power to the STARDOM controller base unit prior to inserting or removing the NFDV161-P00 module.\u003c\/li\u003e\n\u003cli\u003eAlign the module card edges with the designated base chassis guide slots and press firmly until the locking tab engages.\u003c\/li\u003e\n\u003cli\u003eWire field inputs using shielded twisted-pair cabling, terminating 24 VDC field power and dry contacts per channel assignment drawings.\u003c\/li\u003e\n\u003cli\u003eConnect cable shield drains to the local enclosure grounding bar to ensure effective noise attenuation.\u003c\/li\u003e\n\u003cli\u003eVerify that field signal loop impedance and sensor drive levels align with the nominal 10 kOhm input impedance before energizing.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":48701953441982,"sku":"NFDV161-P00","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-08-12_10-54-30_e9cef639-fb55-49eb-8812-de48811673b2.png?v=1786611816","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-nfdv161-p00-digital-input-module-1","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
