KNX DALI L4 bc 16 A

Actuator for DALI Light Control, 4 Outputs.

The Actuator KNX DALI L4 bc 16 A is an interface between KNX bus system and DALI lighting system (Digital Addressable Lighting Interface). The interface has four channels for DALI lighting control, each of which can control up to 64 DALI devices (electronic ballasts). Control is via broadcast message, i.e. all participants on a channel are switched/dimmed simultaneously. Each channel can be set separately.

Each channel has a switched relay contact through which the DALI devices can be switched completely de-energised (no standby). The KNX DALI L4 bc 16 A supplies the DALI bus voltage, no external DALI bus voltage supply is required.

With the KNX DALI L4 bc 16 A, the colour and colour temperature (Tunable White) can be set for DALI EVGs with device type 8. Both colour settings can be controlled by scenes, relative or absolute dimming.

In addition to normal operation, the KNX DALI L4 bc 16 A has a night mode and staircase lighting function with prewarning function (and both in combination).

Buttons on the devi e allow direct manual switching and dimming of the connected DALI EVGs even without bus voltage. The LEDs indicate whether the relay is open or closed (upper LEDs) and whether the lamp is on or off after a DALI command (lower LEDs). The DALI EVGs can be controlled by the ETS with the buttons for commissioning on site without KNX power supply and without prior configuration.
