Growlink lightLINK 4-Channel 0-10V Light Controller

Four Lighting Zones, One Repeatable Dimming Strategy

The Growlink LINKS 4 Channel lightLINK brings 0-10V analogue dimming to four independent lighting zones, each channel driving up to 50 fixtures. LEDs, digital ballasts or a mixed setup all pull into Growlink OS, so every room follows the same recipe – sunrise and sunset ramping included. It is a rugged module built for greenhouse and indoor conditions, with optional DIN rail mounting, and part of the modular LINKS ecosystem.

Key Benefits

• Four independent 0-10V channels, each controlling up to 50 fixtures on its own schedule
• Smooth analogue dimming from low intensity in propagation to full output in flower
• Wide compatibility with the major 0-10V dimmable fixtures, so mixed-brand rooms behave as one system
• Automated sunrise and sunset ramping, set per room from a single dashboard
• Cuts energy waste by holding each zone at the intensity the crop needs
• Simple wiring: 24V DC input, 0.125A per channel and 0.5A maximum overall, with mounting kit and a 10ft (3m) RJ-45 cable supplied

Why Do Two Rooms on the Same Recipe Finish Differently?

Manual dimmers and standalone timers cannot standardise light levels across zones. One room ends up over-driven, another under-lit, and results diverge – excessive stretch in the dim room, bleached tops in the bright one, low yields in whichever got forgotten. Centralised analogue dimming removes the human error and applies the same intensity curve everywhere, run after run.

How to Use

• Mount the module on the supplied kit or DIN rail, near the fixtures it drives
• Wire each zone to one of the four 0-10V channels, staying within 50 fixtures per channel
• Supply 24V DC and link back to the controller with the supplied 10ft (3m) RJ-45 cable
• Build your lighting recipe in Growlink OS – intensity per zone, per stage, with ramp times either side of the photoperiod
• Ramp rather than switch at lights-on to spare young or freshly transplanted plants the shock of full intensity
