An integrated galvanic barrier enforces a 2 kV AC input-to-output dielectric isolation rating for 1 minute, preventing field-side electrical surges from damaging the low-voltage processor backplane. The module tracks internal thermal profiles continuously, engaging a non-latching thermal protection circuit if component temperatures cross safe thresholds. The S2 suffix designates standard integration of ISA Standard G3 conformal coatings, which actively prevent copper creepage and trace corrosion caused by ambient hydrogen sulfide, sulfur dioxide, or high humidity levels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the load balancing behavior when two modules operate in a redundant configuration?\u003c\/p\u003e\n\u003cp\u003eA: The redundant pairing utilizes internal diode auctioneering circuits to handle load allocation. If one module experiences a drop in input voltage or an internal component failure, the secondary power supply assumes the full 10 A load current without causing voltage dips on the 5 V DC backplane bus.\u003c\/p\u003e\n\u003cp\u003eQ: Can this module be hot-swapped while the FIO baseplate is actively powered?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module supports online replacement under live system conditions. The integrated overcurrent and soft-start circuits suppress inrush currents during insertion, preventing localized voltage drops that could disrupt the operation of adjacent active I\/O modules.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eBaseplate Slot Alignment\u003c\/strong\u003e: Slide the housing straight into the dedicated power supply slot of the FIO baseplate, ensuring the rear connector pins line up correctly with the backplane socket before applying force to lock the tabs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Power Termination\u003c\/strong\u003e: Fasten the 24 V DC input lines via the designated MIL connector cable, verifying that the input voltage remains within the stable 20.4 to 26.4 V DC operational parameters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding Protocols\u003c\/strong\u003e: Connect the FIO baseplate ground lug directly to the dedicated instrumentation master ground rail using low-impedance copper conductors to ensure proper functioning of the 2 kV AC isolation barrier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Clearance Limits\u003c\/strong\u003e: Maintain unobstructed vertical clearance around the module chassis to facilitate natural convection, ensuring that the ambient operating temperature inside the cabinet does not exceed +70 deg C.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43778181431386,"sku":"ATRBS-00 S2","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/178_d038836e-441a-401d-ac7f-f0aaffcc8779.jpg?v=1785727022","url":"https:\/\/www.spareoil.com\/ar\/products\/atrbs-00-s2-yokogawa-fio-redundant-power-supply-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
