TrolMaster Dry Contact Station (DSD-3) - 5.51 x 3.54 x 1.97-in - 1A Relay Output

Switch Terminal Devices On and Off From Your Controller - Single Relay

Some cultivation equipment has no direct link to your environment controller, so it stays on manual control. The DSD-3 works as a peripheral driver that turns a terminal device ON or OFF on command from a compatible TrolMaster controller. It provides an isolated dry-contact output with a 1A rating, and it functions solely as an isolated switch.

At 5.51 x 3.54 x 1.97 in and 0.46 lb, this single unit suits growers adding one switched device to an existing TrolMaster setup, whether in a home room or a larger indoor facility that needs another relay point.

Key Features & Benefits

• Single relay with NO and NC contacts — choose the contact that matches how your device should behave.
• Isolated dry-contact output — the station only switches, so it does not supply power to the device.
• Contact rating of 1A@250VAC and 1A@30VDC — clear limits for planning your wiring.
• RJ12 cable and T-splitter included — you can connect it to your controller without sourcing extra parts.
• Rated for 32-104°F and up to 90% RH — defined operating conditions for room planning.

Who Should Use TrolMaster DSD-3 Dry Contact Station

Growers who run Hydro-X, Aqua-X, Carbon-X or Green-X controllers and want to automate a device that needs a simple switched contact. It fits home and commercial cultivation rooms alike.
