Downlight Relay


The DC Downlight Relay Dimmer provides a 1000 mA DC output contact closure relay, 0-10V dimming output, and Direct Connect© Sensor port.  This flexible module can be used as a small form factor controller for downlights and other small fixtures that do not have dim to off drivers. The controller can also be used as general purpose contact closure output without the dimming lines to drive output commands to external relays, building control systems, or any other use requiring contact closure output.

Relay Dimmers are part of the Avi-on™ Bluetooth with Mesh product ecosystem supported by the Avi-on mobile app, commissioning tools, and cloud IoT Services.

Any output command from the Avi-on network can be directed to the Relay Dimmer including motion sensors, daylight harvesting, wall stations, and schedules

The Downlight Relay Dimmer comes with an external antenna for flexible mounting options in metal enclosures.


DC Fixture Controller

The Downlight Relay Controller works with 12~24V DC, controlling fixtures up to 1A.  The small form factor allows it to fit within the wiring box of individual downlights, and can also support a Direct Connect sensor to add motion sensing and daylight control for downlights.  The relay can disconnect power to the LEDs to support drivers that do not dim to off.  The relay can be wired on the LED (DC side of the driver) to support AC constant current 1-10v drivers with less than 24V max voltage and 1A maximum current.  See wiring diagram below.

Contact Closure Output

The Downlight Relay Controller cans also be used as a generic contact closure output for control of circuit level relays in control panels (DC powered), external commands to building control systems, VAV boxes, custom indicator lights, or other uses that need an on/off signal based on a command from the Avi-on Network.
