DALI 4-channel dimmer

Code: EK-GL1-DL

DALI bus device to be supplied with 12 / 24 / 48 Vdc. It

provides the dimming control function for LED sources, by

means for several commands: KNX pushbuttons or other

local command devices.

Description

The ekinex DALI 4-channel dimmer EK-GL1-DL allows

brightness control of dimmable LED sources by means

of several types of button. It can be connected by me-

ans of KNX (TP) pushbutton connected to a DALI / KNX

Gateway or via another device, directly connected to the

dedicated input, selectable from a normally open button,

0-10V analog input, 1-10V analog input and 10 kΩ poten-

tiometer. The device has an integrated DALI bus com-

munication module and requires a 12, 24 o 48 Vdc input

power supply.
