Expand the capacity of your Toro TSM‑8 expansion module to add eight additional irrigation stations to a Toro TMC‑424 series controller. This modular station module is designed for professional residential and commercial irrigation systems, delivering reliable 24 VAC station outputs, automatic station numbering, and a compact form factor that installs directly into the controller to extend watering coverage without replacing the entire unit.

  • 8 additional stations: Instantly increases controller capacity by eight stations for larger lawns or added zones.
  • Compatible with TMC‑424 series: Designed specifically for Toro TMC‑424/TMC‑424E modular controllers for straightforward integration.
  • 24 VAC station outputs: Standard 24 VAC output per station; supports station run times from 1 minute to 8 hours.
  • Hot‑swappable installation: Install or remove the module while the controller remains powered; the controller automatically recognizes module position and station numbering.
  • Surge protection options: TSM‑8 is offered as a standard surge module; flange variants (TSM‑8F) and high‑surge versions (TSM‑8H) are available for specific site requirements.
  • Modular reliability: Compact design fits into the TMC cabinet and is sold individually with manufacturer SKU TSM‑8 for easy ordering and replacement.

This expansion module is ideal when you need more zones without replacing the base controller—perfect for adding new beds, drip lines, or remote irrigation areas. Refer to the controller manual for exact load limits and installation diagrams before adding multiple modules. If you need assistance choosing the right surge protection or checking total controller load, consult product documentation or a qualified irrigation technician.
