What is the DSD-1 dry contact module and how does the it work?

The DSD-1 is a Dry-contact module, meaning it has a 6-Amp SPDT relay inside of it and can be used to activate devices that require a simple relay contact or switch closure to turn a device on & off.

The DSD-1 can be addressed to become a temperature, humidity, CO2 or timer module and it offers a normally open and normally closed contact with a single common connection.

The DSD-1 can be configured to work like the other Trolmaster "Device Station (DS)" power modules work. The DSD-1 is a dry-contact "relay" that has connections for normally open and normally closed. You can hard-wire the DSD-1 into many devices to control: Lighting contactors, Light Deprivation curtains, Pump contactors, Temperature devices, Humidity devices, CO2 devices
