The Trolmaster DSV-1 is a low voltage output module that can be used on Hydro-X and Aqua-X controllers. The DSV-1 can be addressed for use as a temperature, humidity, CO2, or timer module.

The user can select multiple voltage outputs. The DSV-1 can output 12 or 24 VDC at up to 0.5 amps, or 12 or 24 VAC at up to 4.8 VA. Once the module is configured, it will power the low voltage device wired to the DSV-1.

This allows the user to directly connect low voltage devices such as solenoids, valves, audio-visual alarms, or any other device that requires 12 to 24 volts AC or DC power to operate.

By pressing and holding the top button on the DSV-1, users can manually override the module and turn it on/off.
