Who This Is For

  • You are automating your multi-zone feeding because manually opening solenoid valves takes up your whole morning.
  • You are expanding your irrigation capacity because your single-line setup cannot keep up with growing canopy demands.
  • You are consolidating your valve controls because managing six separate power bricks for solenoids is a wiring mess.

What We Found

  • The individual LEDs are a lifesaver when you need to verify zone activity without pulling out a multimeter.
  • We prefer the one-button addressing over older modules that make you mess with dip switches or software mapping.

What Users Say

  • Users who automated their feed cycles say they finally stopped losing plants to missed manual waterings.
  • Operators running large facilities say daisy-chaining these modules made expanding to 30 zones surprisingly simple.

TrolMaster Aqua-X OA6-24 24V Solenoid Control Board

Managing solenoid valves manually across a large irrigation setup isn't scalable — and a controller is only as useful as the hardware it can actually drive. The TrolMaster OA6-24 24V Control Board bridges your TrolMaster Aqua-X NFS-1 Irrigation Control System to your low-voltage solenoid valves, providing six individually controlled 24V AC outputs from a single module. Each output has its own LED indicator so you can confirm active zones at a glance, and daisy-chain connectivity via dual RJ12 sockets means you can expand the system as your operation grows — connecting up to five OA6-24 modules to a single Aqua-X controller to manage up to 30 solenoid valves in total.

Setup is straightforward: connect via RJ12, press the addressing button to link the module to the controller, and your irrigation zones are ready to schedule and automate.

Compatibility: TrolMaster Aqua-X, Green-X, and Hydro-X HCS-2 Grow Tent Control Systems


What's Included

  • 1 × 24V Control Board (OA6-24)
  • 1 × 16ft RJ12 Cable

Features

💧
24V AC Solenoid Valve Support

Designed specifically for low-voltage 24V AC solenoid valves — the standard used in most irrigation and fertigation setups.

🔢
6 Individually Controlled Outputs

Six independent 24V outputs per module let you schedule and control each irrigation zone separately from the controller.

💡
Per-Output LED Indicators

Each of the six outputs has a dedicated LED indicator showing active or inactive status — confirm zone activity at a glance.

🔗
Daisy Chain Connectivity

Dual RJ12 sockets allow modules to be daisy-chained. Connect up to 5 OA6-24 units to one controller to manage up to 30 valves.

📍
One-Button Addressing

Onboard addressing button links the module to your controller in a single press — no software or configuration tools required.

🔌
Plug & Play Setup

RJ12 cable included. Connects directly to the controller with no additional wiring or hardware required.

FAQs

What type of solenoid valves is the OA6-24 designed for? +

The OA6-24 is designed specifically for solenoid valves that operate on 24V AC — the standard low-voltage specification used in the majority of irrigation and fertigation valve setups. Each of the six outputs delivers 24 VAC at up to 0.2A. If your valves run on 110V AC instead, see the TrolMaster OA6-110 Environmental Control which is designed for that voltage range.

How many solenoid valves can I control with one OA6-24? +

Each OA6-24 provides six individually controlled outputs, so a single module can drive up to six solenoid valves independently. By daisy-chaining up to five OA6-24 modules to a single Aqua-X controller, you can scale the system to manage up to 30 solenoid valves in total.

How do I expand beyond six zones? +

The OA6-24 features dual RJ12 sockets that allow multiple modules to be daisy-chained together. Connect additional OA6-24 units in sequence to expand your zone count in increments of six — up to five modules (30 zones) per controller. Each module is addressed individually so the controller can identify and schedule each zone separately.

How do I address (link) the OA6-24 to my controller? +

After connecting the OA6-24 via RJ12 cable, press the onboard addressing button once to link the module to your controller. When multiple OA6-24 modules are daisy-chained, each unit must be addressed individually so the controller can distinguish between them and schedule irrigation zones independently.

What do the LED indicators on each output show? +

Each of the six outputs on the OA6-24 has a dedicated LED indicator that shows whether that output — and therefore that irrigation zone — is currently active or inactive. This allows you to confirm at a glance which valves are open and running without needing to check the controller display or physically inspect each valve.

Which controllers is the OA6-24 compatible with? +

The OA6-24 is compatible with the TrolMaster Aqua-X NFS-2 Irrigation Control System as its primary use case, and also works with the Green-X and Tent-X environmental control systems. It connects via standard RJ12 cable and integrates directly into the TrolMaster control ecosystem.

Is there a version of this board for 110V solenoid valves? +

Yes — the TrolMaster OA6-110 Environmental Control is the 110V AC equivalent of the OA6-24, designed for solenoid valves that operate at line voltage rather than the low-voltage 24V AC standard. Both modules share the same six-output layout and daisy-chain capability. Choose the version that matches your valves' operating voltage.
