89452937-DES DALI-2 Expander

The DALI-2 Expander DES is a compact device used to expand the DALI line. The device is connected to the DALI line (DALI IN terminals) and behaves like a DALI ballast with a DALI address. Devices connected to the output of the DALI-2 Expander (DALI OUT terminals) form a subordinate DALI line. The DALI operating devices in the sub-line are controlled broadcast via the address of the DALI-2 Expander. For the model with article number 89452937-DES, the devices in the DALI sub-line can also be controlled via Switch&Dim.

The DALI-2 Expander has an integrated DALI bus power supply (25mA or 200mA, depending on the device design) to supply the sub-line. In addition to expanding the number of operating devices, the Expander can also be used to increase the cable length by 300 meters.

Available housing variants:

• For DIN rail mounting
• For remote control/ceiling mounting
• For installation in luminaires
