SwitchME4 DALI

Analog - DALI compatible relay

The SwitchME4 DALI 4CH relay is a DALI compatible relay. Device designed to allow for the independent switching of four devices (luminaires and others) through a DALI interface.
On the front panel of the device can be found an integrated push button for the manual control of the relays for testing purposes, additional to five device status indicator LEDs.

The device is housed in a standard DIN-rail mountable box for easy installation in electrical switchboards.

After powering-up the device an internal test sequence is initiated that lasts for no more than two seconds. The device then acts in normal mode and awaits DALI commands.

The "STATUS" LED indicator is lit when the DALI BUS is correctly supplied. LED indicators one to four show the current status of each relay:
a lit LED means the corresponding relay is switched on, an unlit LED means the corresponding relay is switched off.

Test mode

  •    Test mode can be activated at any time by pressing the push button "TEST"
  •    A short push of the button, for a period less than three seconds, changes which relay is selected, indicated by the corresponding LED indicator blinking
  •    By pressing the push button for a period of more than three seconds the selected relay is switched on / off, indicated by the way in which the LED indicator blinks (predominantly on means the relay is switched on, predominantly off means the relay is switched off)
  •    The device will return to normal mode after five seconds of push button inactivity
