Streamline your grow room wiring with the TrolMaster SPH-1 Splitter Hub, the professional solution for organized and reliable system expansion. Designed to eliminate the mess of "daisy-chaining" multiple Y-splitters, the SPH-1 acts as a central nervous system for your environment. It takes a single input from your controller and provides eight individual ports to connect sensors, device modules, or light adapters, ensuring a clean and efficient installation.
Why Choose the SPH-1?
In large-scale or complex setups, signal loss can be a hidden enemy. The SPH-1 is more than just a junction box—it is a powered hub. When using the included 12V power supply, it boosts the communication signal across all connected lines. This ensures that every command from your controller reaches your lights and modules instantly, allowing for the management of an almost unlimited number of LED or HID fixtures without lag or interference.
Core Benefits & Standout Features
  • Centralized Connectivity: Features eight (8) RJ12 output jacks, allowing you to run individual cables to each device from one central location rather than linking them one by one.
  • Active Signal Boosting: The powered internal circuitry strengthens data transmissions, preventing signal degradation over long cable runs or high-density equipment setups.
  • Clean Installation: Replaces bulky daisy-chain configurations with a sleek, organized hub, making troubleshooting and cable management significantly easier.
  • Universal Utility: Compatible with the full range of TrolMaster sensors and device modules, including Hydro-X, Aqua-X systems. and tent-X
  • Versatile Power Options: Flexible design allows you to use it with or without the power adapter depending on your specific hardware needs (e.g., lighting vs. sensors).
Technical Breakdown
  • Inputs/Outputs: 1x RJ12 Input Port | 8x RJ12 Output Ports.
  • Power Requirement: 12VDC (Power supply included).
  • Durability: Built to withstand grow room conditions, operating reliably in temperatures from 32°F to 122°F.
  • Plug & Play: No software or complex configuration required; works immediately upon connection.
Package Contents
  • 1 x SPH-1 Splitter Hub
  • 1 x 12V DC Power Adapter
  • 1 x 4ft RJ12 Connection Cable
Organize your grow. The TrolMaster SPH-1 is the key to a professional-grade, scalable environment that stays connected and responsive.
Pro-Tip: If you are using the SPH-1 to connect your lighting systems to a single LMA adapter, do not plug in the 12V power supply unless you are using the LMA-T or ThinkGrow systems.

Expand Your TrolMaster System with Clean, Reliable Connectivity

The TrolMaster SPH-1 RJ12 Splitter Hub makes it easy to expand your Hydro-X, Aqua-X or Tent-X control system by providing eight RJ12 output ports from a single controller connection. Instead of daisy-chaining multiple Y-splitters, the SPH-1 creates a clean, organised installation while making it simple to connect additional sensors, lighting adapters and device stations as your grow operation grows.

More than just a splitter, the SPH-1 is a powered signal booster, strengthening communication between your controller and connected devices. This allows growers to build much larger automation systems and even control almost unlimited numbers of compatible LED and HID grow lights when used with the appropriate TrolMaster lighting adapters. It's an essential accessory for commercial growers looking to build a scalable, professional environmental control system.

Expand Your Hydro-X System

Frequently Asked Questions

The SPH-1 is a powered RJ12 Splitter Hub that expands your TrolMaster controller by providing one RJ12 input and eight RJ12 output ports, allowing multiple sensors, adapters and device stations to be connected neatly from one central location.

The SPH-1 creates a much cleaner installation, reduces cable clutter and eliminates the need to daisy-chain multiple Y-splitters, making your system easier to install, expand and maintain.

Yes. Unlike a standard splitter, the SPH-1 is a powered hub that boosts communication signals, allowing more sensors, modules and lighting adapters to be connected reliably across larger installations.

The SPH-1 works across multiple TrolMaster platforms, including:
Hydro-X
Aqua-X
Tent-X
Carbon-X
and other compatible RJ12-based TrolMaster systems.

Yes. The SPH-1 allows multiple lighting adapters to be connected, making it possible to control very large LED or HID lighting installations from a single TrolMaster controller.

Yes. The package includes:
SPH-1 RJ12 Splitter Hub
12V DC Power Adapter
16 ft RJ12 Communication Cable
ready for plug-and-play installation.

Yes. If you're using the SPH-1 to connect multiple lighting systems back to a single LMA lighting adapter (except the LMA-T and ThinkGrow lighting systems), do not connect the 12V DC power supply to the SPH-1. Follow the manufacturer's guidance for this specific configuration.

The SPH-1 is ideal for commercial growers, greenhouse operators and advanced indoor growers who need to expand their TrolMaster system with additional sensors, lighting adapters or device stations while maintaining reliable communication and a tidy installation.
