The Trolmaster DSD-1 Dry Contact Module provides a simple and flexible solution for users who wish to connect to Hydro-X or Aqua-X powered and monitored devices using a “dry contact” or relay to activate the device. Many devices require the closure of a dry contact to be controlled or activated. The DSD-1 is the product you need to control such devices.

The DSD-1 can be configured to have the same functions as other TrolMaster power modules. The DSD-1 plugs into the Hydro-X’s “device” line and can be configured to control a nearly infinite number and types of devices such as:

• Lighting Contactors
• Light Deprivation Curtains
• Pump Contactors
• Temperature Devices
• Humidity Devices
• CO2 Devices

By holding down the top button on the DSD-1, users can manually override the module and turn it on/off.
