The Toro TSM-4 is a modular 4-station expansion module designed to add four additional irrigation zones to compatible Toro TMC controllers. It provides reliable 24VAC valve outputs and a weather-resistant enclosure for indoor or outdoor installations. Adds 4 stations: Expand your TMC controller by four zones per module, enabling flexible system growth without replacing the main controller. Compatible with TMC series: Designed for use with Toro TMC controllers, including the TMC-424 family, for straightforward integration into existing systems. 24VAC valve outputs: Standard 24VAC outputs allow direct valve control; wire valves directly to the module's terminal strip for each station. Rugged, weather-resistant enclosure: Built for indoor or outdoor use; reseller listings report an IP54 enclosure rating—confirm with Toro documentation for your region. Modular, plug-in design: Plug-in expandability reduces downtime and inventory needs; add modules as your system grows to increase station capacity. Simple wiring and service access: Clear terminal access simplifies installation and future servicing by trained technicians or professional installers. Ideal for residential and light-commercial irrigation projects, the TSM-4 delivers a compact, reliable way to increase the capacity of your Toro TMC irrigation system.
