DALI Expander Unit 89453847

DALI Expander Unit 89453847 | 89452937 for DALI System Expansion with Integrated Bus Supply

The DALI expander can be used to set up your own DALI sub-circuit and supply it with energy and information. In this way, additional DALI operating devices in the DALI sub-circuit can be broadcast controlled via the address of the DALI expander. Alternatively, the DALI Expander can also control the DALI devices in the sub-circuit directly via its switch & dim button input. It has an integrated DALI bus supply (200mA) for 90 DALI devices in the sub-circuit. In addition to increasing the number of electronic ballasts in a DALI circuit, the expander can also be used to extend the cable length of usually up to 300m.

Product Properties / Features:

• DALI expander unit for expanding a DALI circuit and controlling several DALI devices via one DALI address
• For the higher-level DALI circuit, the DALI expander behaves like a DALI ECG (DALI IN) with a DALI address
• Broadcast forwarding of the DALI commands received at the input (DALI IN) to the output (DALI OUT)
• Output (DALI OUT) with DALI power supply (200mA) for supplying DALI ECGs and DALI control devices
• Alternative control option for the DALI output circuit via the switch & dim input (broadcast)
• Galvanic separation between the DALI circuits
• Available as
  • DIN rail module (for installation in protection class II devices)
  • Independent control gear (for ceiling installation or luminaire Installation)
