Because channels share a non-isolated common ground structure, signal conditioning circuits filter out high-frequency noise and prevent cross-channel interference. Cold junction compensation (CJC) algorithms are managed at system marshalling panels when interfacing remote temperature transmitters via current transducers.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What grounding precautions must be observed due to the non-isolated channel architecture of the AAI141-H00 S2?\u003c\/p\u003e\n\u003cp\u003eA: Since input channels share a common ground reference, all connected 4-20 mA loops must originate from isolated loop power supplies or isolated transmitters to prevent circulating ground currents across the card.\u003c\/p\u003e\n\u003cp\u003eQ: How does HART communication pass through the analog signal chain without distorting 16-bit conversion?\u003c\/p\u003e\n\u003cp\u003eA: HART frequency-shift keying (FSK) signals operate at higher frequencies (1200 Hz and 2200 Hz) overlaid on the 4-20 mA DC signal; internal active low-pass filtering removes these FSK components prior to A\/D sampling.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInsert the module firmly into the CENTUM baseplate slot until the upper and lower locking levers snap into position.\u003c\/li\u003e\n\u003cli\u003eRoute 4-20 mA current loop wiring using shielded twisted-pair conductors, terminating the cable shield at the designated cabinet grounding bar rather than on the module terminal block.\u003c\/li\u003e\n\u003cli\u003eVerify that the external 24 VDC loop power supply voltage remains steady under full 16-channel load conditions.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":52842886529304,"sku":"AAI141-H00 S2","price":170.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/AAI141-H50_Cocoai_a2018e99-4dda-4aab-ae6b-e6fffe93caf7.jpg?v=1791596984","url":"https:\/\/www.innoplcsync.com\/products\/yokogawa-aai141-h00-s2-analog-input","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
