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

Independent 120VAC Device Control for Grow Room Automation with the Growlink QuadLINK

The Growlink™ LINKS QuadLINK Switching Module delivers precise, independent control of up to four 120VAC devices within indoor growing environments, connecting seamlessly to the Growlink system via the LINKS HUB for centralized automation management. Capable of switching devices up to 6 amps each (9A max combined), the QuadLINK supports a wide range of common cultivation equipment — including irrigation pumps, CO₂ systems, circulation fans, and supplemental lighting — giving cultivators flexible, automated device control from a single module.

With three operation modes — manual, scheduled, and sensor-based — the QuadLINK adapts to diverse automation strategies across different devices and growth phases. Its rugged, durable construction ensures dependable performance in demanding agricultural settings, and its integration with Growlink OS provides remote monitoring, automation programming, and real-time status visibility through the Growlink app or web dashboard. Made in the USA.

Key Features & Benefits

• Controls up to 4 devices independently — each channel operates separately, allowing different devices to run on different schedules or automation triggers simultaneously.
• 120VAC / 9A max combined — supports standard 120VAC devices up to 6A per channel for broad compatibility with common cultivation equipment.
• Three operation modes — manual, scheduled, and sensor-based automation provide flexibility to match the control strategy to each device's role in the grow environment.
• Growlink HUB integration — connects via the LINKS HUB for centralized management and monitoring of all connected devices through Growlink OS.
• Supports diverse cultivation devices — controls irrigation pumps, CO₂ systems, fans, lights, and other 120VAC equipment from a single module.
• Rugged, durable construction — engineered for reliable long-term performance in the demanding conditions of active indoor grow facilities.
• Made in the USA — built to commercial agricultural standards for professional-grade reliability.

Who Should Use the Growlink QuadLINK

The QuadLINK is ideal for commercial cultivators and facility operators who need to automate multiple 120VAC devices within a grow room using the Growlink platform. It is particularly valuable in operations where irrigation pumps, CO₂ enrichment systems, and environmental control devices need to be coordinated through a single automation controller with flexible scheduling and sensor-driven response capabilities.

Coordinated Device Automation for Indoor Cultivation Efficiency

Effective indoor cultivation requires precise coordination of multiple environmental systems — irrigation, CO₂, air circulation, and lighting must work together in response to both schedules and real-time conditions. The QuadLINK's four independent channels allow cultivators to manage this coordination through Growlink OS, creating automated workflows where devices respond to sensor data, time schedules, and manual overrides from a single, accessible interface. The result is a more responsive, efficient, and consistent growing environment with less manual management overhead.

Frequently Asked Questions

How many devices can the QuadLINK control simultaneously?

The QuadLINK supports up to four independently controlled 120VAC device channels simultaneously. Each channel can operate on its own schedule or automation rule, running different devices concurrently.

What is the maximum load per channel?

Each channel supports up to 6 amps at 120VAC. The total combined load across all four channels must not exceed 9 amps.

Does the QuadLINK require a Growlink HUB?

Yes. The QuadLINK connects to the Growlink platform via the LINKS HUB. A Growlink HUB is required for integration with Growlink OS, remote management, and sensor-based automation.

What is the difference between the QuadLINK and the RelayLINK?

The QuadLINK controls 120VAC devices (pumps, fans, CO₂, lights) with 4 independent channels. The RelayLINK controls 24VAC low-voltage signals (HVAC systems, humidifiers, dehumidifiers) with 6 dry-contact channels. They target different device voltage classes and serve complementary roles in a complete grow room automation system.

Can sensor data from Growlink sensors trigger QuadLINK device responses?

Yes. In sensor-based mode, QuadLINK channels can be triggered by data from connected Growlink sensors — for example, turning on a CO₂ system when CO₂ drops below a set level, or activating an irrigation pump based on substrate moisture readings.
