{"product_id":"qbp867654","title":"Vimar By-me Plus Line Coupler, 29V Nominal Supply, DIN Rail TH35, Electrical Isolation, Message Filtering","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Vimar VM01845.1 is a line coupler used to connect two By-me Plus bus lines while keeping the lines electrically separated. It works on a 29 V bus supply, draws 30 mA, and mounts on a DIN 60715 TH35 (EN 50022) rail, taking up 2 DIN modules (35 mm) in your electrical cabinet.\u003c\/p\u003e\u003cp\u003eOn a boat, this is typically installed in the main distribution panel or an automation cabinet when the bus layout needs two powered sections, or when two lines need to communicate without tying the wiring together directly. The unit must be powered from both sides, so each connected line should have its own bus power available.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eCouples two By-me Plus bus lines while maintaining electrical separation between the lines\u003c\/li\u003e\n\u003cli\u003eRated supply voltage: 29 V bus; the device must be powered from both sides\u003c\/li\u003e\n\u003cli\u003eCurrent draw: 30 mA\u003c\/li\u003e\n\u003cli\u003eDissipated power: 800 mW average, 1100 mW maximum\u003c\/li\u003e\n\u003cli\u003eDIN rail mounting on DIN 60715 TH35 (EN 50022); occupies 2 modules of 17.5 mm (35 mm total)\u003c\/li\u003e\n\u003cli\u003eFilters bus traffic so only relevant messages pass between lines, with a manual routing mode available\u003c\/li\u003e\n\u003cli\u003eConfigured using the View Pro app; the Function button supports reset and manual routing functions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis coupler is intended for Vimar By-me Plus bus installations that use a 29 V bus supply. It is not a KNX, KNX-RF, or LON coupler.\u003c\/p\u003e\u003cp\u003eBecause it is a DIN device, it belongs inside a protected electrical cabinet rather than in an exposed location. Plan space for a 2-module unit and leave room for clean cable routing and strain relief, especially in high-vibration installs.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eClip the unit onto a TH35 DIN rail and wire each bus side to match your system topology. In marine panels, keep bus wiring organized and supported so vibration does not work connections loose over time.\u003c\/p\u003e\u003cp\u003eConfiguration is handled through the View Pro app. The Function button provides a reset procedure and a manual mode that routes all messages, with an automatic timeout after 2 hours.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eThis is a low-voltage bus device, so treat its cabling and terminations like any other SELV circuit on board. In mixed-voltage cabinets, keep mains conductors (230 V AC) physically separated from SELV wiring to reduce noise pickup and to keep the panel serviceable.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eCommon layouts include splitting an automation backbone between zones such as salon and cabins, or joining a secondary panel into the same By-me Plus system while keeping each side independently powered. It is a practical fit for refits where the bus is being extended into a new area of the vessel and you want clearer segmentation between lines.\u003c\/p\u003e","brand":"Vimar","offers":[{"title":"Default Title","offer_id":52269504987317,"sku":"QBP867654","price":545.04,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1300225_qbp867654.jpg?v=1771544336","url":"https:\/\/www.qualityboatparts.com\/products\/qbp867654","provider":"Quality Boat Parts","version":"1.0","type":"link"}
