It connects directly to the base controller to add 12 additional control stations, allowing irrigation professionals and landscape contractors to manage larger properties or more complex zone layouts without replacing the existing controller. The module is built to integrate seamlessly with the SL1600 platform, maintaining centralized programming and scheduling from the host unit. At 20 pounds, it is a substantial hardware component suited for commercial and large residential irrigation installations.\u003c\/p\u003e\n\u003cp\u003eThis expansion module is used in irrigation systems where the base SL1600 controller has reached its native station capacity and additional zones are required.
