It integrates with 4-20 mA HART loop protocols where upstream modules require discrete input translation. Cold junction compensation is applied to stabilize signal detection from devices subjected to ambient temperature drift. FOUNDATION Fieldbus and Profibus PA connectivity options are supported when integrated with hybrid I\/O configurations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum input frequency for pushbutton detection?\u003cbr\u003eA: The module supports up to 25 Hz maximum ON\/OFF cycle for pushbutton inputs.\u003c\/p\u003e\n\u003cp\u003eQ: Can the module be hot-swapped while the system is powered?\u003cbr\u003eA: Yes, the NFDV161-P50 supports removal and insertion without shutting down the STARDOM controller, provided wiring integrity is maintained.\u003c\/p\u003e\n\u003cp\u003eQ: How is galvanic isolation managed between channels?\u003cbr\u003eA: Each channel is fully isolated, with 2 kV AC isolation to the system and 500 V AC between commons for every 16-channel group.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the module in the designated STARDOM rack slot and secure mechanical fasteners before energizing.\u003c\/li\u003e\n\u003cli\u003eUse shielded twisted-pair cabling for field inputs to minimize cross-talk.\u003c\/li\u003e\n\u003cli\u003eConnect MIL or clamp terminals per pinout diagram, verifying peel length and wire gauge.\u003c\/li\u003e\n\u003cli\u003eGround the module shield to the system common to reduce transient noise injection.\u003c\/li\u003e\n\u003cli\u003eAvoid routing high-current power cables adjacent to input signal wiring to maintain isolation integrity.\u003c\/li\u003e\n\u003cli\u003eVerify all input channels are within 20–26.4 VDC ON range before commissioning.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":44165710151768,"sku":"NFDV161-P50","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/NFDV161-P50-3.jpg?v=1780367247","url":"https:\/\/www.industriaxplc.com\/ar\/products\/digital-input-module-yokogawa-nfdv161-p50","provider":"IndustriaX Limited","version":"1.0","type":"link"}
