Its non-isolated channel configuration provides analog signal acquisition for a Yokogawa control system. The module is intended for applications requiring multiple current-input signals to be collected through a single I\/O module.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\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\u003eNFAI141-S01\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\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAnalog Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Platform\u003c\/td\u003e\n\u003ctd\u003eSTARDOM FCN\/FCJ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e16\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\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eNon-isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllowable Input Current\u003c\/td\u003e\n\u003ctd\u003e27 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power ON)\u003c\/td\u003e\n\u003ctd\u003e250 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Power OFF)\u003c\/td\u003e\n\u003ctd\u003e500 kohm or more\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-0.1% of full scale\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Refresh Cycle\u003c\/td\u003e\n\u003ctd\u003e10 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Step Response Time\u003c\/td\u003e\n\u003ctd\u003e100 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Drift\u003c\/td\u003e\n\u003ctd\u003eMax. +\/-0.01%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Power Supply\u003c\/td\u003e\n\u003ctd\u003e22.8-26.4 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmitter Output Current Limit\u003c\/td\u003e\n\u003ctd\u003e27 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current Consumption\u003c\/td\u003e\n\u003ctd\u003e310 mA at 5 VDC; 450 mA at 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Connection\u003c\/td\u003e\n\u003ctd\u003ePressure clamp terminal or MIL connector cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eSignal Processing and Channel Configuration\u003c\/h3\u003e\n\u003cp\u003eThe module accepts 4-20 mA current signals from field transmitters and converts them into measurement data for the controller. The 16-channel arrangement allows multiple process variables to be acquired through one module. Its non-isolated design means the input channels do not provide individual galvanic isolation, which should be considered when evaluating field wiring and grounding arrangements.\u003c\/p\u003e\n\u003cp\u003eThe specified input accuracy of +\/-0.1% of full scale describes the measurement deviation relative to the configured full-scale range. The 10 ms data refresh cycle and 100 ms input step response time describe different aspects of signal performance: controller data updating and the response to a change in the input signal.\u003c\/p\u003e\n\u003ch3\u003eTransmitter and Wiring Requirements\u003c\/h3\u003e\n\u003cp\u003eThe NFAI141 hardware specification supports both 2-wire and 4-wire transmitter configurations. Each channel is configured through its setting pin. When using a 2-wire transmitter, the analog field power supply terminal of the power supply module must receive 24 VDC. The transmitter supply has a specified output current limit of 27 mA.\u003c\/p\u003e\n\u003cp\u003eThe module supports pressure clamp terminal connections and MIL connector cable connections. Yokogawa's field connection documentation identifies the NFTA4S terminal block and a 40-pin MIL connector arrangement for the NFAI141 module. The actual connection hardware should be checked against the installed system configuration.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the NFAI141-S01 accept both 2-wire and 4-wire transmitters?\u003c\/p\u003e\n\u003cp\u003eA: The NFAI141 hardware supports both transmitter types. Each channel requires the corresponding setting-pin configuration, and 2-wire transmitter applications require the specified 24 VDC analog field power supply.\u003c\/p\u003e\n\u003cp\u003eQ: Does this module provide channel-to-channel isolation?\u003c\/p\u003e\n\u003cp\u003eA: No. The NFAI141 is specified as a non-isolated 16-channel analog input module. Applications requiring isolated input channels should not treat this model as equivalent to an isolated analog input module.\u003c\/p\u003e\n\u003cp\u003eQ: What connection options are available?\u003c\/p\u003e\n\u003cp\u003eA: The NFAI141 supports pressure clamp terminal connections and MIL connector cables. The documented terminal block combination is NFTA4S with a 40-pin MIL connection option.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":69254188400882,"sku":"NFAI141-S01","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/NFAI141-S012.jpg?v=1794195128","url":"https:\/\/www.petrospare.com\/products\/yokogawa-nfai141-s01-16-channel-analog-input-module","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
