DCS Instrumentation\u003c\/h3\u003e\n\u003cp\u003eThe module processes 16 non-isolated 4 to 20 mA current loops across an internal 10 ms data update period, converting analog process variables into 16-bit digital values. Built-in transmitter power circuitry supplies field instruments with a minimum terminal voltage of 14.8 VDC at 20 mA, capped by an active current-limiting threshold of 27 mA. When the node chassis loses operating power, input resistance shifts to 500 kohm or greater to maintain electrical isolation across attached field loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the non-isolated channel architecture affect field signal wiring?\u003c\/p\u003e\n\u003cp\u003eA: All 16 input channels share a common internal signal ground reference, requiring connected 2-wire and 4-wire field transmitters to operate on equal ground potential to prevent loop current distortion.\u003c\/p\u003e\n\u003cp\u003eQ: What interface connection does the \/K400 option code supply?\u003c\/p\u003e\n\u003cp\u003eA: The \/K400 option mounts an ATK4A-00 adapter to the module front faceplate, establishing a direct connection point for prefabricated multi-core KS interface cables.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInsert the module into the designated slot of the FIO node chassis along the plastic guide rails until the rear header seats into the backplane bus. Hand-tighten the top and bottom panel retention screws to secure mechanical alignment and establish chassis grounding connections.\u003c\/p\u003e\n\u003cp\u003eLatching fasteners secure the multi-core KS cable to the front ATK4A-00 adapter. Route input cabling through dedicated low-voltage wireways, maintaining a minimum clearance of 200 mm from three-phase AC power lines. Connect cable shielding to the main cabinet grounding bus at a single ground point to suppress high-frequency electrical noise.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":67662830633059,"sku":"AAI141-S00\/k400","price":360.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/345._0ca82415-1293-49ac-8b1f-559fc3648d11.jpg?v=1791424698","url":"https:\/\/www.autocontrolglobal.com\/products\/aai141-s00-k400-yokogawa-centum-vp-analog-input-module","provider":"AutoControl Global","version":"1.0","type":"link"}
