The push button coupler is a module with 4 contact
inputs for regular push buttons and switches. It
communicates and it is powered from the DALI channel.

Its small size allows it to be installed behind standard
wall switches and push buttons.

Four digital inputs

There are 4 digital inputs (dry contact) designed for conventional pushbuttons or switches. These inputs facilitate seamless integration with standard pushbutton or switch controls.


Mutil-master, up to 32 per DALI channel.

DALI Bus Powered

Powered directly from the DALI channel. This ensures efficient integration and operation without the need for additional power sources.

DALI-2 Support

Can integrate up to 32 DALI-2 input devices (control devices) per DALI channel. Light sensors, occupancy sensors and buttons can be configured via the web interface and made accessible to BACnet.

Compact design

Designed for optimal mounting behind standard switches.

Integrated Wires

Built-in wires for connecting the push button and switches.

Via the DALION lighting controller, the connected push
buttons and switches can control luminaries on the DALI
channel. The DALION allows for the following
commands and more:

✓ Off, On
✓ Dim Up and Down
✓ Direct Value
✓ Recall Scenes 1-16
✓ Last On Level
✓ Occupancy
✓ Daylight Harvesting
✓ Demand Response



The bus wiring must be connected in a star topology, a linear topology, or a mixture of the two. Wiring must not be carried out in a ring structure. The two wires that serve as the bus must be located in the same cable or cable conduit. In the cable or cable conduit, the two wires must be side by side to avoid unintentional coupling to other signals.
