{"product_id":"trolmaster-rj12-splitter-hub-with-cable-set","title":"TrolMaster RJ12 Splitter Hub with cable set","description":"\u003cp\u003eThe TrolMaster SPH-1 is a powered RJ12 splitter hub designed to expand the connectivity of Hydro-X, Hydro-X Pro, Hydro-X Plus, and Carbon-X control systems. It accepts one RJ12 connection from the main controller and provides 8 individual RJ12 output ports for connecting sensors, device stations, lighting adapters, and other compatible TrolMaster modules. Unlike a passive splitter, the SPH-1 actively boosts\/regenerates the signal and provides supplemental 12V power for compatible devices.\u003c\/p\u003e\n\n\n\u003cp\u003e• SKU: SPH-1\u003cbr\u003e\n• Brand: TrolMaster\u003cbr\u003e\n• Compatible Systems: Hydro-X (HCS-1), Hydro-X Pro (HCS-2), Hydro-X Plus (HCS-3), Carbon-X\u003cbr\u003e\n• Input Voltage: 12 VDC\u003cbr\u003e\n• Maximum Current: 1A\u003cbr\u003e\n• RJ12 Input Ports: 1\u003cbr\u003e\n• RJ12 Output Ports: 8\u003cbr\u003e\n• Signal Type: Active \/ powered signal boosting\u003cbr\u003e\n• Included RJ12 Cable: 16 ft (approx. 4.9 m)\u003cbr\u003e\n• Power Supply: 12 VDC power supply included\u003cbr\u003e\n• Working Temperature: 32–122°F (0–50°C)\u003cbr\u003e\n• Working Humidity: ≤90% RH, non-condensing\u003cbr\u003e\n• Dimensions: 160 × 85 × 90 mm\u003cbr\u003e\n• Compatible Devices: TrolMaster sensors, device stations, lighting adapters, CO₂ stations, smoke detectors, and other compatible RJ12 modules\u003cbr\u003e\n• Multiple Hubs: Multiple SPH-1 hubs can be used within a TrolMaster system, subject to the controller-specific device limits\u003cbr\u003e\n• Special Requirement: Required for supplemental 12V power for certain modules, including the MBS-Pro sensor\u003cbr\u003e\n• Installation: One RJ12 cable from controller → SPH-1 → up to 8 downstream devices\u003cbr\u003e\n• Important Lighting Note: When used solely to connect multiple lighting adapters back to one LMA adapter, the 12V power supply may need to remain disconnected depending on the specific lighting-adapter configuration\u003cbr\u003e\n• In the Box: 1× SPH-1 hub, 1× 16-ft RJ12 cable, 1× 12VDC power supply\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The SPH-1 changes a simple single RJ12 connection into an 8-port powered hub while actively regenerating the signal, making it more suitable than passive Y-splitters for larger installations with multiple sensors, device stations, and lighting adapters. It also provides the supplemental power required by certain TrolMaster modules.\u003c\/p\u003e","brand":"Hydro Supply Co.","offers":[{"title":"Default Title","offer_id":67610181795876,"sku":"TRLM-SPH-1","price":37.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0254\/3914\/1924\/files\/rj12-splitter-hub-with-cable-set-sph-1.webp?v=1791317590","url":"https:\/\/www.growitdepot.com\/products\/trolmaster-rj12-splitter-hub-with-cable-set","provider":"Grow It Depot","version":"1.0","type":"link"}
