Integrated isolated bus pathways maintain signal fidelity across connected 4-20 mA HART loop protocol interface cards and digital I\/O nodes.

Secure the ground earth terminal directly to the enclosure grounding bar using a low-impedance copper strap to establish proper protective earth continuity.\u003c\/p\u003e\n\u003cp\u003eMaintain a minimum clearance of 50 mm above and below the chassis to permit unimpeded air circulation. Route incoming 24 VDC power lines and ESB bus communication cables through dedicated, shielded wire channels, maintaining at least 300 mm separation from high-voltage AC conductors.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43873259225178,"sku":"NFBU200-S","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/858..jpg?v=1787193179","url":"https:\/\/www.spareoil.com\/products\/yokogawa-nfbu200-s-base-unit-centum-vp-esb-bus-chassis","provider":"SpareOil Automation","version":"1.0","type":"link"}
