Dry Contact Station Single Pack with cable set.

Switch Equipment That Needs a Dry-Contact Signal

Some grow room equipment doesn't accept direct power switching at all, instead needing a normally open or normally closed contact closure to trigger its own internal relay. The TrolMaster DSD-1 dry contact station fills that gap on the Hydro-X system, closing or opening a dry contact rather than switching line power directly.

Beyond its own dry-contact function, the DSD-1 can be reconfigured to behave like a DST, DSH, or DSC power module, which makes it a useful spare to keep on hand for a facility running several device-station types.

Key Features & Benefits

• Normally Open or Closed Output — matches whichever contact type the connected equipment's control input requires.
• Module Emulation — can be reconfigured to function like a DST, DSH, or DSC power module.
• LCD Status Display — shows the station's current configuration and activation state.
• Wiring Hardware Included — arrives with a 16 ft RJ12 cable, a 4 ft RJ12 cable, and a T-splitter.

Who Should Use the DSD-1 Dry Contact Station

Growers with equipment that requires a dry-contact or relay signal to activate, rather than a standard powered outlet, need the DSD-1 instead of one of the direct-switching device stations. It also suits facilities that want one flexible spare module on hand instead of stocking every device-station type.

About TrolMaster

TrolMaster gives its Hydro-X device-station lineup this kind of flexible, emulation-capable module precisely because grow-room electrical needs vary; the Sacramento, California-designed DSD-1 is built to fill whichever gap the more specific modules don't cover. That flexibility is part of a broader modular philosophy that runs through the company's controller hardware.

Frequently Asked Questions

What kind of equipment needs the DSD-1?

Equipment requiring a normally open or normally closed dry-contact signal to activate, rather than direct power switching. This includes some third-party relays and control panels.

Can the DSD-1 act like other TrolMaster modules?

Yes, it can be configured to work like the DST, DSH, or DSC power modules. That makes it a useful universal spare for a Hydro-X system.

What's included with the DSD-1?

The dry contact station ships with a 16 ft RJ12 cable, a 4 ft RJ12 cable, and a T-splitter. No additional wiring accessories are needed for a standard installation.

Does it include a status indicator?

Yes, an LCD display shows the module's current configuration and activation status. That makes it easy to confirm which emulation mode is active.

How do I switch the DSD-1 between emulation modes?

Emulation mode is set through the station's own configuration menu on its LCD display. No additional hardware or rewiring is needed to switch between modes.
