TrolMaster RJ Splitter HUB SPH-1


The SPH-1 Splitter Hub by TrolMaster makes installation of thier controllers as easy as plugging in a phone cable. The SPH-1 hub uses a single RJ12 cable input jack, and provides 8 individual RJ12 output jacks that can be connected to various TrolMaster sensors, adapters & device modules. Using the SPH-1 allows for a neat/tidy & generally clean installation which eliminates the need for the use of daisy-chain Y-splitters to be used to interconnect multiple modules or sensors reducing excess coils of cables in the grow room.

The SPH-1 is also a powered hub, meaning that it will boost the signals passing through the SPH-1 allowing more modules, sensors and light adapters to be connected to the TrolMaster controllers. By using the SPH-1, an almost unlimited number of LED/HID lights can be controlled using a single TrolMaster controller. The SPH-1 comes complete with the SPH-1 hub, a 16 foot RJ12 cable and the 12vdc power supply.

The SPH-1 can be located in a central location with a single RJ12 cable connecting it to the main controller. From the SPH-1 hub, the individual RJ12 jacks can be connected to each of the sensors, device modules, or lighting adapters.

NOTE: If you are using the SPH-1 to interconnect your lighting systems together back to a single LMA adapter (except for LMA-T and ThinkGrow lighting system), DO NOT connect the 12 volt dc power supply to the SPH-1.
