The TrolMaster RJ12 Splitter Hub (SPH-1) facilitates the installation of sensors, modules, and adapters by providing a centralized and organized connection. Instead of using multiple chain splitters (Y-splitters), the SPH-1 allows you to connect up to 8 RJ12 devices in a clean and efficient manner.
The SPH-1 also has the function of boosting the signal of all connections that pass through this module, allowing you to connect as many sensors and light adapters as necessary. Using the SPH-1, you can control an almost unlimited number of LED / HID luminaires with a single TrolMaster controller.
IMPORTANT: if you use the SPH-1 to interconnect the luminaires in a single LMA adapter module (except for the LMA-T adapter and ThinkGrow luminaires), DO NOT connect the 12v dc power supply to the SPH-1
