TrolMaster Low-Volt Station

Power Solenoids, Valves, and Alarms Directly From Hydro-X

Solenoids, valves, and audiovisual alarms typically run on low-voltage AC or DC power rather than line voltage, which normally means sourcing a separate power supply just to trigger them. The TrolMaster DSV-1 removes that extra step, delivering selectable 12 or 24 volt output directly from the Hydro-X or Hydro-X Pro system to whatever low-volt device is wired to it.

The module itself can be addressed as a temperature, humidity, CO2, or timer device depending on configuration, so the same hardware adapts to whichever condition should trigger the connected device.

Key Features & Benefits

• Selectable Voltage Output — supplies 12 or 24 volts, in AC or DC, to match the connected device.
• Assignable Control Type — configures as a temperature, humidity, CO2, or timer module.
• LCD Display — supports on-site setup and status viewing without a separate app.
• Direct Hydro-X Integration — connects to the HCS-1 and HCS-2 controllers without an external power supply.

Who Should Use the DSV-1 Low-Volt Station

Growers who need to power solenoids, valves, or alarms directly from their Hydro-X system, without sourcing and wiring a separate low-voltage transformer, are the intended users of the DSV-1. It removes a common point of extra hardware in irrigation and alarm setups.

About TrolMaster

The DSV-1 extends TrolMaster's HCS-1 and HCS-2 Hydro-X controllers, both engineered at the Sacramento, California company's headquarters, to reach low-voltage devices that standard line-voltage device stations aren't built to power. It's one of several accessory modules the company designs to round out a single-zone control build.

Frequently Asked Questions

Which controllers support the DSV-1?

The HCS-1 and HCS-2 Hydro-X controllers. It is not designed for use with the HCS-3 or the standalone BETA-series controllers.

What output voltages are available?

12 or 24 VDC up to 0.5A, or 12 or 24 VAC up to 4.8VA. The specific output depends on how the module is configured.

Can I use the DSV-1 for more than one function?

Yes, it can be addressed as a temperature, humidity, CO2, or timer device module. Only one function is active at a time per module.

What's included with the DSV-1?

A low-volt station, a cable set, and an RJ12 T-splitter. No separate low-voltage power supply is needed for compatible devices.

How do I change which condition triggers the DSV-1?

The control type is set through the module's configuration menu on the controller, choosing temperature, humidity, CO2, or timer. No rewiring is needed to switch between these modes.
