Growlink LINKS 4 Channel LightLINK Lighting Controller — 0-10V Outputs Control up to 50 Fixtures Per Channel

Control Up to 200 Fixtures Across Four Independent 0-10V Dimming Channels

Large lighting installations need zone-by-zone control, not just a single on/off switch for the whole room. The Growlink 4-Channel LightLINK Controller drives four independent 0-10V analog dimming channels, each capable of running up to 50 compatible fixtures, giving a single controller command over as many as 200 fixtures split across separate zones or rooms.

Scheduling and dimming curves are managed through Growlink OS, letting growers ramp intensity gradually at sunrise and sunset or tie lighting output to other environmental triggers rather than running fixtures at a flat, unchanging level.

Key Features & Benefits

• Four Independent Dimming Channels: Control separate zones or rooms from a single controller.
• Up to 50 Fixtures Per Channel: Supports up to 200 total 0-10V dimmable fixtures per controller.
• 0-10V Analog Dimming: Compatible with the industry-standard dimming protocol used by most commercial grow lighting.
• Growlink OS Scheduling: Program sunrise and sunset ramps or tie dimming to other environmental data.
• Optional DIN Rail Mounting: Installs cleanly into a control panel using the Growlink DIN Rail Mounting Kit.

Who Should Use This

Commercial cultivators running large fixture counts across multiple rooms or zones who need centralized, scheduled 0-10V dimming control are the direct fit for the 4-Channel LightLINK Controller, particularly facilities looking to automate sunrise and sunset ramping rather than switching fixtures abruptly.

About Growlink

Since 2015, Growlink has built lighting and environmental control hardware under its LINKS brand, aiming to give commercial cultivators zone-level control from a single Growlink OS dashboard.

Frequently Asked Questions

How many fixtures can this controller support in total?

Each of the four channels supports up to 50 compatible 0-10V fixtures, for a maximum of 200 fixtures across the full controller. Actual fixture capacity per channel can depend on the specific driver's current draw, so check your fixture's specifications.

Can each channel run a different dimming schedule?

Yes, the four channels operate independently, so each can be programmed with its own schedule, dimming curve, or intensity target through Growlink OS. This supports rooms on different photoperiods running from the same controller.

Is this controller compatible with all grow light fixtures?

It is compatible with fixtures that accept a standard 0-10V analog dimming signal, which covers most commercial LED and HPS grow lighting. Confirm your specific fixture's dimming input type before wiring it to this controller.

Can this controller be mounted in a control panel with other LINKS devices?

Yes, it supports optional DIN rail mounting using the Growlink LINKS DIN Rail Mounting Kit, letting it sit alongside other LINKS modules in the same enclosure. This keeps larger automation panels organized as more devices are added.
