Commercial & Bulk Purchasing
We support operations & licensed facilities with volume pricing, dedicated account managers, and custom equipment consultation.
Who This Is For
- You are consolidating your irrigation control because managing multiple zones with single ports is a wiring mess.
- You are adding more solenoids because your current controller lacks the outputs to manage high-density layouts.
- You are switching to volume-based feeding because timer-only cycles fail to account for fluctuating line pressure.
What We Found
- The Phoenix connectors make wiring much cleaner than traditional terminals when you are managing all 12 zones.
- The universal voltage input is a huge help since you do not need to hunt for external transformers during setup.
What Users Say
- Commercial growers who daisy-chained these modules say they finally stopped worrying about manual valve overrides.
- Users who switched to volume-based mode report more consistent runoff levels compared to using standard timers.
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

TrolMaster backs the OAT-24 with a 3-year warranty from the original date of purchase, covering all mechanical and electronic components under normal operating conditions. Components that fail due to abnormal or improper usage are excluded from this coverage.
FAQs
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.
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.
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.
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.
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.
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.
