It extends high-speed optical Extended Serial Backplane (ESB) communication lines natively at the physical-layer tier, allowing real-time, deterministic signal routing across distant I\/O nodes parallel to master processor network execution cycles.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eYNT511D-P42 (Configuration: YNT511D-P42\/KT)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApprox. 8 lbs (3.6 kg unpopulated)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e19.0\" × 7.0\" × 12.0\" (48.3 cm × 17.8 cm × 30.5 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRack Profile\u003c\/td\u003e\n\u003ctd\u003eStandard 19-inch industrial rackmount 4U configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlot Capacity\u003c\/td\u003e\n\u003ctd\u003e13 dedicated slots for optical ESB repeater modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperational Input Voltage\u003c\/td\u003e\n\u003ctd\u003e24 V DC nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003eMaximum 60 mA (Base chassis draw excluding modules)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGalvanic Isolation\u003c\/td\u003e\n\u003ctd\u003e1 kV DC electrical isolation threshold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Focus\u003c\/td\u003e\n\u003ctd\u003eOptical ESB bus network expansion and signal regeneration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eIndustrial Control \u0026amp; DCS Architecture\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhysical-Layer Network Extension and Signal Regeneration:\u003c\/strong\u003e The YNT511D-P42 acts as a localized optical-to-electrical and electrical-to-optical signal conditioning matrix. By eliminating attenuation across long fiber-optic runs, the rack permits distributed I\/O nodes to be placed kilometers away from the central Field Control Station (FCS) while keeping communications tightly synchronized.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Density Modular Expansion Slotted Backplane:\u003c\/strong\u003e Featuring a 13-slot backplane layout, the unit provides scalable density matching for complex network structures. It hosts optical bus repeater modules that organize incoming star or line topologies into a unified data stream, matching the token-passing intervals of the master system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic Isolation and Electrical Isolation Barriers:\u003c\/strong\u003e Built with an internal 1 kV DC isolation barrier, the rack structurally detaches the local power distribution traces from the shared optical transceiver bus logic. This prevents ground loops, lightning surges, or electrical faults at remote nodes from migrating across the fiber lines into the core controller matrix.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What specific hardware behaviors manifest if the incoming 24 V DC supply voltage exhibits a ripple transient beyond nominal parameters?\u003c\/p\u003e\n\u003cp\u003eA: The rack's internal voltage regulation circuits filter minor fluctuations. However, if the supply drops below operational thresholds, the optical modules will encounter transceiver jitter. This causes the host FCS to flag cyclic redundancy check (CRC) errors, register communication retries, and eventually trigger an ESB network link failure alarm.\u003c\/p\u003e\n\u003cp\u003eQ: Can individual optical ESB repeater modules be hot-swapped within the 13 slots while the YNT511D-P42 is live and processing network data?\u003c\/p\u003e\n\u003cp\u003eA: No. Unless the specific optical module and system version explicitly support live online maintenance, removing or inserting a transceiver module can generate a transient electrical disruption across the shared backplane bus lines, breaking token synchronization and interrupting communication to downstream I\/O racks.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":47705122701502,"sku":"YNT511D-P42","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-06-24_12-01-06.png?v=1782279320","url":"https:\/\/www.autooiltech.com\/ar\/products\/yokogawa-ynt511d-p42-optical-bus-repeater-rack","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
