Connect & Automate Almost Any Grow Room Device with Dry Contact Control

The TrolMaster DSD-1 Dry Contact Station gives growers the flexibility to integrate and automate equipment that operates using normally open (NO) or normally closed (NC) dry contact signals. Compatible with the Hydro-X and Aqua-X control systems, the DSD-1 makes it possible to automate a huge range of third-party equipment—including lighting contactors, irrigation pumps, blackout curtains, HVAC systems and CO₂ devices—creating a smarter, more efficient growing environment.

Unlike standard power modules, the DSD-1 doesn't supply power directly to equipment. Instead, it acts as a relay trigger, making it ideal for commercial growers who need to integrate existing control systems into their TrolMaster setup. With plug-and-play installation, an integrated LCD display and manual override, the DSD-1 provides reliable automation while helping maintain stable environmental conditions for healthier crops and improved yields.
