TrolMaster RJ12 Splitter Hub (SPH-1)

Effortless Expansion & Clean System Organization for TrolMaster Controllers

The TrolMaster SPH-1 RJ12 Splitter Hub is the ultimate solution for simplifying and expanding your TrolMaster environmental control system. Designed to eliminate messy wiring and multiple Y-splitters, the SPH-1 provides a clean, centralized way to connect up to eight sensors, device modules, or lighting adapters using a single RJ12 input.

Unlike passive splitters, the SPH-1 is a powered hub, boosting communication signals to ensure reliable performance across large installations with multiple modules and long cable runs. This enhanced signal strength allows growers to connect far more devices—including LED and HID lighting systems—through a single TrolMaster controller without signal loss or instability.

Perfect for Hydro-X, Hydro-X Pro, Aqua-X, and Tent-X users, the SPH-1 enables streamlined system organization, easier troubleshooting, and plug-and-play expansion. It also includes everything needed to get started: a 16 ft RJ12 cable and a 12VDC power supply.

✔ Central Hub with 8 RJ12 Outputs

Replace messy Y-splitters with a clean, efficient connection hub for sensors, adapters, and device modules.

No complicated wiring—simply plug in via RJ12 cables.

do NOT connect the 12VDC power supply.
