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. For complete installation instructions, wiring diagrams, compatibility details and warranty information, consult Toro's official manual or contact Toro support.
