12 Outputs 24V Control Board

Scale Up Irrigation Control Across Multiple Zones

The Aqua-X Pro system's largest commercial installations need more output density per board than a 6-output module provides, along with more sophisticated per-valve control than a simple on/off timer. The TrolMaster OAT-24 module is designed specifically for the Aqua-X Pro Irrigation Control System, featuring 12 individual 24V outputs that can each control a 24-volt irrigation solenoid.

By connecting multiple OAT-24 modules, the Aqua-X Pro system can manage up to 600 individually controlled 24V valves, each independently configurable across five modes: Recycle, Schedule, Demand, Volume, or Auto-fill.

Key Features & Benefits

• 12 Individual 24V Outputs — controls one 24-volt irrigation solenoid per output.
• Scales to 600 Valves — expands by connecting multiple OAT-24 modules together.
• Five Control Modes — sets Recycle, Schedule, Demand, Volume, or Auto-fill per valve.
• Simplified Schedule Management — manages irrigation across multiple nutrients, rooms, and zones.

Who Should Use the OAT-24 Control Board

Aqua-X Pro Irrigation Control System users who need to manage irrigation schedules across multiple rooms, nutrients, or zones, at a scale beyond what a 6-output OA6 board handles, are the intended users of the OAT-24. It's built specifically for the Pro-tier system rather than the base NFS-1.

About TrolMaster

The OAT-24 is the highest-density output board in TrolMaster's Aqua-X Pro accessory lineup, engineered at the Sacramento, California company's headquarters for facilities running valve counts well beyond a handful of zones. Its five configurable control modes give commercial growers per-valve flexibility that a simpler timer board doesn't offer.

Frequently Asked Questions

How many outputs does the OAT-24 have?

12 individual 24V outputs. That's double the output density of the OA6 board series.

How many valves can the Aqua-X Pro manage with multiple modules?

Up to 600 individually controlled 24V valves. Reaching that ceiling requires connecting multiple OAT-24 modules together.

What control modes are available?

Recycle, Schedule, Demand, Volume, or Auto-fill. Each of the 12 outputs can be set to a different mode independently.

What's the operating temperature range?

32-122°F. That covers typical indoor grow-room and greenhouse conditions.
