Growlink LINKS QuadLINK Switching Module — 120VAC 9A Controls up to 4 Devices via Growlink HUB

Automate Four 120VAC Grow Room Devices Independently From One Module

Irrigation pumps, CO2 systems, circulation fans, and supplemental lighting are all common 120VAC loads in an active grow room, and switching each one manually adds up to a lot of daily attention. The Growlink QuadLINK Switching Module controls up to four such 120VAC devices independently, connecting through the Growlink HUB for centralized scheduling and monitoring.

Each of the four channels handles up to 6A, with 9A supported combined across all channels, and three operation modes — manual, scheduled, and sensor-based — let different devices run on whatever control logic fits them best.

Key Features & Benefits

• 4 Independent 120VAC Channels: Each channel switches its own device on its own schedule or trigger.
• Up to 6A Per Channel, 9A Combined: Covers a wide range of common 120VAC cultivation equipment.
• Three Operation Modes: Manual, scheduled, and sensor-based control fit different devices to different automation strategies.
• Growlink HUB Integration: Connects via the LINKS HUB for centralized monitoring through Growlink OS.
• Supports Diverse Equipment: Switches irrigation pumps, CO2 systems, fans, lights, and similar 120VAC loads.

Who Should Use This

Cultivators automating multiple 120VAC devices in a single room who want manual, scheduled, and sensor-triggered control options from one module are the direct fit for QuadLINK, particularly operations coordinating irrigation, CO2, and circulation equipment together.

About Growlink

Since its founding in 2015, Growlink has built switching and relay hardware to bring powered cultivation equipment under centralized Growlink OS control.

Frequently Asked Questions

How many devices can the QuadLINK control at once?

QuadLINK supports up to four independently controlled 120VAC device channels running simultaneously. Each channel can follow its own schedule or automation rule.

What is the maximum load per channel?

Each channel supports up to 6A at 120VAC, with a combined maximum of 9A across all four channels. Verify your connected equipment's draw against these limits before wiring.

Does the QuadLINK need a Growlink HUB?

Yes, the QuadLINK connects to Growlink OS through the LINKS HUB, which is required for remote management and sensor-based automation. Without a HUB connection, the module can still switch devices but loses remote scheduling and sensor-triggered control.

How is the QuadLINK different from the RelayLINK?

QuadLINK switches higher-voltage 120VAC devices such as pumps, fans, and lights across four channels. RelayLINK instead switches low-voltage 24VAC climate equipment such as HVAC and humidifiers across six channels. The two modules target different device classes and are typically deployed together rather than as substitutes.
