Commercial & Bulk Purchasing
We support operations & licensed facilities with volume pricing, dedicated account managers, and custom equipment consultation.
Who This Is For
- You are integrating high-draw dehumidifiers or CO2 generators into your controller network because standard outlets keep tripping under heavy load.
- You are upgrading your facilitys environmental management because your existing device stations cannot handle the continuous amperage of professional-grade equipment.
What We Found
- We suggest this module for any heavy-duty equipment since the relay contacts are built to withstand 25A without heating up.
- The RJ12 daisy-chaining is reliable but we recommend keeping these units away from high-moisture exhaust paths to ensure long-term port integrity.
What Users Say
- Growers who swapped out their standard 15A stations for the DSR-1 report that they finally stopped seeing intermittent power failures on their largest heaters.
- Managers of larger facilities say that using these to consolidate their heavy-load devices has made troubleshooting their climate circuits much simpler.
TrolMaster DSR-1 25A High-Current Relay Station
Managing high-power equipment in a commercial grow environment often presents a challenge when standard 15A device stations reach their limit. The TrolMaster DSR-1 Environmental Control solves this by providing a robust 25A high-current relay, allowing you to safely manage large electric heaters, commercial-grade humidifiers, and high-capacity CO2 generators without the risk of overloading your environmental control system. While other modules like the TrolMaster DFM-3 Digital Flow Meter focus on monitoring, the DSR-1 is built for heavy-duty power delivery.
This versatile module integrates perfectly with your existing TrolMaster ecosystem. Whether you are using a Hydro-X Pro HCS-2 or Hydro-X Plus HCS-3 controller, the DSR-1 can be assigned as a temperature (DST), humidity (DSH), CO2 (DSC), or timer (DSP) station. With built-in overload protection and a universal voltage range of 100–277V, it offers the reliability and flexibility needed for professional cultivation facilities, much like the precision control found in the TrolMaster EFC-1 EC Fan Control Adapter.
Compatibility: TrolMaster Hydro-X Pro, Aqua-X Pro, Carbon-X, Green-X, and Tent-X Systems

FAQs
When do I need the DSR-1 instead of a standard device station?
If your climate device (heater, humidifier, or CO2 generator) draws more than 15A, the DSR-1 is required. Standard TrolMaster stations like the 4RS-2 4-Outlet Device Station are capped at 15A, whereas the DSR-1 handles up to 25A continuous load.
What roles can the DSR-1 be assigned?
The DSR-1 is highly versatile and can be configured as a temperature station (DST), humidity station (DSH), CO2 station (DSC), or timer station (DSP) within your controller settings.
Is the DSR-1 compatible with 240V systems?
Yes, the DSR-1 features a universal voltage range of 100–277V, making it compatible with standard 120V and 240V North American electrical circuits.
Does it include overload protection?
Yes, the DSR-1 includes integrated overload protection to protect both the relay station and your expensive climate equipment from excessive current draw.
Which controllers work with the DSR-1?
It is fully compatible with the TrolMaster Hydro-X, Aqua-X, Carbon-X, Green-X, and Tent-X systems using standard RJ12 communication cabling.
