The TrolMaster DSD-1 is a universal dry-contact relay module that brings equipment requiring normally open (NO) or normally closed (NC) contact closure under centralized TrolMaster control. It provides the interface between Hydro-X, Aqua-X, or Carbon-X controllers and equipment such as lighting contactors, light-deprivation curtain motors, irrigation pump contactors, CO₂ systems, and other contactor-based equipment. It connects through the TrolMaster RJ12 device line and includes a complete cable set for plug-and-play integration.

• Typical Applications: Lighting contactors, blackout curtain motors, irrigation/fertigation pump contactors, CO₂ equipment, dehumidifiers, humidity equipment, and temperature-control peripherals
• Included Cable Set: 1× 16-ft RJ12 cable, 1× 4-ft RJ12 cable, 1× RJ12 T-splitter
• Packaging Dimensions: 85 × 80 × 90 mm
• Direct Mains Switching: The DSD-1 is primarily a dry-contact interface; it is intended for equipment that requires a contact-closure signal rather than a conventional switched outlet.
Key Advantage: The DSD-1 acts as a flexible integration bridge between TrolMaster automation and equipment with its own contactor/control circuit. Unlike dedicated DST, DSH, or DSC stations, its NO/NC dry contacts can be assigned to different control functions, making it useful for larger contactor-based equipment and non-standard devices.
