Take full control of your grow room without the cable chaos. The AC Infinity UIS Splitter Hub 4-Port lets you distribute smart programming from a single controller port to up to four compatible UIS devices simultaneously — so your fans, lights, and humidifiers all respond as one unified system. Whether you're running a compact tent or a multi-tier commercial setup, this hub makes scaling your automation effortless and clean.
Why the AC Infinity UIS Splitter Hub 4-Port
Most growers hit a wall when they want to automate multiple devices from a single controller — either they're limited by port count or forced into mismatched programming. The UIS Splitter Hub solves this by expanding one UIS controller port into four synchronized outputs, allowing all connected same-type devices to follow identical programming without any additional configuration. It's plug-and-play simplicity with professional-grade results.
Unlike generic splitters or workarounds, this hub is purpose-built for the AC Infinity UIS ecosystem. It supports up to three tiers of daisy-chained hubs, meaning you can build out a multi-level array of grow equipment all governed by a single controller port. Premium cable construction ensures a firm, reliable connection every time — no signal degradation, no dropped commands, no guesswork.
Key Benefits
- 1-to-4 Port Expansion – Splits one UIS controller port into four outputs so multiple devices share the same smart programming simultaneously.
- Synchronized Device Control – All connected same-type devices follow identical programming, eliminating the need to configure each unit individually.
- Multi-Tier Daisy Chaining – Link additional hubs together in up to three tiers to build a scalable, multi-level grow equipment array.
- Broad UIS Compatibility – Works with CONTROLLER 69, CONTROLLER 69 PRO, CONTROLLER 69 PRO+, and all future UIS controllers and devices.
- Premium Cable Construction – Engineered with high-durability cables for a firm, secure connection with UIS ports and connectors.
- Plug-and-Play Setup – No software configuration required; simply connect and your devices inherit the controller's programming instantly.
- Versatile Device Support – Compatible with inline fans, humidifiers, LED grow lights, circulation fans, exhaust fans, and more across the AC Infinity lineup.
Use Cases
- Multi-Fan Grow Tent Setups – Run two or more CLOUDLINE inline fans from a single controller port, keeping airflow synchronized across your entire canopy.
- Unified LED Lighting Control – Connect multiple IONBOARD or IONBEAM grow lights to one controller port for consistent light schedules and dimming across all fixtures.
- Humidity Management Arrays – Link multiple CLOUDFORGE humidifiers to a single humidity program so your entire grow space maintains consistent VPD targets.
- Multi-Tier Commercial Grows – Daisy-chain hubs across three tiers to automate large-scale rack systems with dozens of devices under centralized control.
- Grow Room Expansion – Add new UIS devices to an existing controller setup without needing additional controller ports or separate programming profiles.
- Crawl Space & Basement Ventilation – Synchronize multiple AIRTITAN fans across a large space from one controller for consistent airflow management.
Directions for Use
- Connect the hub's input port to an available UIS port on your AC Infinity smart controller using a male-to-male UIS cord.
- Plug your UIS-compatible devices into the hub's four output ports using the male-to-male cords included with each device.
- Ensure all connected devices are the same type (e.g., all inline fans, or all LED lights) — the hub distributes one shared program to all outputs.
- To expand further, connect an additional UIS Splitter Hub to one of the output ports and repeat — up to three tiers are supported.
- Power on your controller and configure your desired program; all connected devices will automatically follow the same settings.
- Note: This hub is not compatible with RJ11/12 Type-A and Type-B adapters.
What Growers Are Saying
"This hub completely cleaned up my tent setup. All four fans run on the same schedule and I only had to program it once. Game changer."
— Marcus T., Commercial Grower
"I daisy-chained two of these across my rack system and now everything runs in sync. Setup took less than five minutes."
— Sarah P., Greenhouse Grower
"Exactly what I needed to expand my AC Infinity setup without buying another controller. Solid build and works perfectly."
— Daniel R., Home Grower
Frequently Asked Questions
Can I connect different types of devices to the same hub?
No — all devices connected to a single hub must be the same type (e.g., all inline fans or all LED lights). The hub distributes one shared program, so mixing device types would result in incompatible commands being sent to different equipment.
How many devices can I control with one hub?
Each hub supports up to four UIS devices. By daisy-chaining additional hubs across up to three tiers, you can significantly expand the number of devices controlled from a single controller port.
Which AC Infinity controllers are compatible?
The hub is compatible with CONTROLLER 69, CONTROLLER 69 PRO, CONTROLLER 69 PRO+, and all future UIS controllers. It is not compatible with RJ11/12 Type-A or Type-B adapters.
Do I need additional cables to use this hub?
Yes — you'll need male-to-male UIS cords to connect your devices to the hub. These cords are included with most UIS devices and are also available for individual purchase from AC Infinity.
Will this hub work with future AC Infinity products?
Yes — the UIS Splitter Hub is designed to be forward-compatible with future UIS devices and controllers as AC Infinity expands their ecosystem.
Does using a hub affect the programming or performance of connected devices?
No — all connected devices receive the exact same programming signal as if they were plugged directly into the controller. There is no signal degradation or performance impact from using the hub.
