{"product_id":"qbp297210","title":"Garmin NMEA 2000 Power Isolator, Data Only, No Power Pass-Through","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Garmin 010-11580-00 is a NMEA 2000 power isolator that lets network data pass while stopping NMEA 2000 bus power from passing through that point in the backbone.\u003c\/p\u003e\u003cp\u003eIt is used when a device on the network can also feed power onto the NMEA 2000 bus, which can lead to the backbone being powered in more than one place. NMEA 2000 networks are powered from 12 Vdc, and connected devices are intended to operate from 9 to 16 Vdc with a nominal 12 Vdc supply.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eAllows NMEA 2000 data communication while blocking network power across the isolator\u003c\/li\u003e\n\u003cli\u003eHelps prevent a connected device from backfeeding power onto the NMEA 2000 backbone\u003c\/li\u003e\n\u003cli\u003eFits inline in the NMEA 2000 backbone between two network segments where power separation is needed\u003c\/li\u003e\n\u003cli\u003eSupports mixed installations where an engine or other equipment may be capable of powering the network\u003c\/li\u003e\n\u003cli\u003eFor NMEA 2000 systems that use 12 Vdc network power (devices typically operate 9 to 16 Vdc)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eInstall the isolator in the backbone between the portion of the network that could introduce bus power and the rest of the backbone. It is placed in-line, not on a device drop, so it separates power paths while keeping the data path intact.\u003c\/p\u003e\u003cp\u003eAfter installation, confirm the network is still built as a proper linear backbone with terminators at both ends, and confirm you are not powering the backbone in more than one place unless an isolator separates those power connections.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis part is for NMEA 2000 networks that use micro-style connectors commonly found on modern marine electronics. If your existing backbone uses NMEA 2000 mini connectors, an adapter is required to interface a micro-connector component into that backbone.\u003c\/p\u003e\u003ch6\u003eElectrical and network considerations\u003c\/h6\u003e\u003cp\u003eThis isolator does not act as a power tap and it does not replace correct network power wiring. The NMEA 2000 backbone should be powered from a switched 12 Vdc source using a dedicated NMEA 2000 power cable, with network loading and voltage drop handled through proper backbone layout and power connection placement.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis is a practical fit for refits where you are adding new electronics to an existing NMEA 2000 backbone, especially when you cannot confirm how the network is powered. It also applies when integrating equipment like certain engines that may be able to supply bus power while still needing to exchange NMEA 2000 data with the rest of the system.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269089226933,"sku":"QBP297210","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298905_qbp297210.jpg?v=1771541810","url":"https:\/\/www.qualityboatparts.com\/products\/qbp297210","provider":"Quality Boat Parts","version":"1.0","type":"link"}
