À TRAVERS LE REGARD DU CULTIVATEUR Évaluation pratique

À qui s'adresse cet article ?

  • You are scaling your irrigation zones because your current controller cannot handle the volume of independent valves.
  • You are centralizing your room management because manually adjusting individual timers is costing you too much labour.

Ce que nous avons découvert

  • The Phoenix type connectors make a real difference during install because they save you from dealing with loose wires.
  • We like that this unit offloads the processing power from your main controller, keeping your system response snappy.

Ce que disent les utilisateurs

  • Operators who integrated these boards say they eliminated the uneven moisture levels across their different crop zones.
  • Users who added these to their greenhouse say the organized wiring reduced their troubleshooting time during harvests.

TrolMaster OAT-24 12-Output 24V Irrigation Control Board

Managing a complex irrigation network across multiple zones often feels like an impossible task when limited by standard controller ports. The TrolMaster OAT-24 Environmental Control solves this scaling bottleneck by providing 12 individually controlled 24V solenoid valve outputs in a single, robust module. Each output is independently programmable, allowing you to tailor your irrigation strategy to the specific needs of different crop types or growth stages. For those monitoring water flow, the OAT-24 pairs perfectly with the TrolMaster DFM-1 to ensure volume-based irrigation accuracy.

The OAT-24 is designed for maximum scalability and precision. By integrating this module with your TrolMaster Green-X GCS-1, you can expand your system's reach to up to 600 valves. This makes it an essential tool for commercial cultivators who require granular control over their greenhouse control environment while maintaining a clean and organized wiring setup via the included Phoenix type connectors.

Compatibility: TrolMaster Green-X and Aqua-X Systems

FAQs

What irrigation control modes does the OAT-24 support?+

Each of the 12 outputs can be independently configured with one of five control modes: Recycle, Schedule, Demand, Volume, or Auto-fill. This allows each irrigation zone to operate on its own logic rather than sharing a single blanket schedule across all zones.

How many OAT-24 modules can I connect?+

Multiple OAT-24 modules can be combined within the same TrolMaster system to scale irrigation capacity. The system supports up to 600 individually controlled valves in total across all connected modules, making it suitable for large commercial greenhouses.

What type of solenoid valves is the OAT-24 compatible with?+

The OAT-24 is designed for standard 24 VAC irrigation solenoid valves, with each output rated at up to 0.5A. This covers the vast majority of commercially available 24V solenoids used in horticultural irrigation systems.

Can the OAT-24 manage irrigation across multiple rooms?+

Yes, the OAT-24 is specifically designed to handle irrigation scheduling across multiple nutrients, rooms, and zones simultaneously. Each output is independently configurable to avoid conflicts between different crop requirements.

Does the OAT-24 work on both 110V and 240V systems?+

Yes. The OAT-24 accepts a universal input of 100–240 VAC at 50/60 Hz, making it compatible with standard electrical infrastructure in North America, Europe, and other regions without additional adapters.

How does the OAT-24 connect to the controller?+

The OAT-24 connects to your TrolMaster controller via the included 16ft RJ12 cable. Solenoid valves wire into the module through the included 13-pin Phoenix type connector for organized and secure field wiring.
