Each channel handles \u003cstrong\u003e50 fixtures max\u003c\/strong\u003e and delivers \u003cstrong\u003e125mA at 24VDC\u003c\/strong\u003e into the dim port. That's enough headroom for Gavita, Fluence, TrolMaster, and most industry-standard 0-10V LED drivers and ballasts. The unit takes 24VDC input from a Growlink HUB through the RJ-45 cable, pulling \u003cstrong\u003e12W max\u003c\/strong\u003e at full load. DIN rail mounting keeps the controller flush in a control panel. Operating range covers 50–122°F (10–50°C) and 0–75% RH non-condensing for greenhouse and indoor cultivation.\u003c\/p\u003e\n\u003ch2\u003eSunrise\/Sunset Ramping Through a Centralized 0-10V Analog Dimming Controller\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eMap each channel to one room or canopy zone. Flowering on channel 1, veg on 2, mother on 3, propagation on 4. The \u003cstrong\u003e0-10V analog dimming controller\u003c\/strong\u003e fires the matching driver inputs from Growlink OS. Place the unit close to the fixture array to keep 0-10V signal runs short. Analog dimming voltage drops over long wire runs and can cause uneven brightness across a row. Sunrise\/sunset ramping is the daily workhorse. Program a 10-30 minute ramp from 10% to 100% at lights-on and reverse it at lights-off to avoid light shock and stretch. Save recipes per crop cycle — veg ramps, flower DLI targets, finishing UV pulses — and reuse them across rooms running the same genetics. The trade-off is that channel-level control isn't fixture-level control. If two fixtures on the same channel need different intensities, split them onto separate channels rather than averaging.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e4× 0-10V Analog Outputs (50 Fixtures Each):\u003c\/strong\u003e Independent dimming across four zones with up to 200 fixtures total at industry-standard 0-10V signaling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGavita, Fluence, TrolMaster Compatible:\u003c\/strong\u003e Plugs into most 0-10V dim ports on commercial LED drivers and ballasts without protocol adapters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunrise\/Sunset Ramping in Growlink OS:\u003c\/strong\u003e Build per-zone ramp profiles, save recipes by crop cycle, and reuse them across rooms running the same genetics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowlink HUB Required, 24VDC Input:\u003c\/strong\u003e Powers from the HUB over RJ-45 and pulls 12W max at full load with 125mA per dim channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN Rail Mounting:\u003c\/strong\u003e Mounts flush in a control panel and keeps signal wiring tidy across a multi-zone lighting build.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;
