The TSM-8F expansion module adds eight valve stations to compatible Toro TMC controllers while providing flow-sensing capability to help detect leaks or pipe breaks. It’s designed for installers who need to scale station count and add basic flow monitoring without extensive rewiring.

  • Expands compatible Toro TMC-424 and TMC-424E controllers by 8 stations for flexible system scaling and straightforward station management.
  • Integrated flow-sensing monitors system flow to help identify leaks, bursts, or abnormal usage and improves troubleshooting response.
  • Hot-swappable design allows installation or removal without powering down the controller; stations are automatically renumbered when modules are changed.
  • Includes standard valve output terminals and a dedicated flow-sensor/master-valve wiring terminal for easy integration with existing field wiring.
  • Compact, service-friendly form factor built to fit the TMC module bays and to simplify field service and upgrades.

Whether upgrading a residential system or expanding a commercial irrigation setup, the TSM-8F provides a practical way to add eight outputs plus flow monitoring while minimizing downtime during installation.
