DALI-2 Expander Unit 89452937

Product information "DALI-2 Expander Unit 89452937"

DALI-2 Expander unit 89452937 for DALI system expansion with integrated bus supply

With the compact DALI-2 Expander 89452937, a separate DALI subcircuit can be set up and supplied with power and information. This means that other DALI operating devices in the DALI sub-circuit can be controlled via the address of the DALI Expander broadcast. Alternatively, the DALI Expander in the 89452937-DES version can also control the DALI devices in the sub-circuit directly via its switch &dim push-button input. The DALI-2 Expander supplies the sub-circuit via an integrated DALI bus supply, with 25mA or 200mA depending on the device version. In addition to increasing the number of control gear/ ECGs in a DALI circuit, the expander can also be used to extend the cable length, which is usually up to 300 metres. There are 3 housing variants available: Top-hat rail, recessed ceiling / luminaire installation and box Installation.

Product Properties / Features:

  • DALI-2 Expander unit for extending a DALI circuit and controlling several DALI devices via one DALI address
  • For the higher-level DALI circuit, the DALI-2 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)
  • Available as
    ◦ DIN rail module (for installation in protection class II devices)
    ◦Independent operating device (for recessed ceiling or luminaire installation as well as box Installation)
