Lunatone DALI-2 line expander, 1 address → broadcast sub-line, 25 mA supply, back box (DALI-2 Expander 89452937-DO)

Compact DALI-2 line expander that appears on the main DALI line as a single device with one address and repeats every command it receives as broadcast on its own subordinate DALI line. One address can thus control many additional drivers, and the sub-line adds up to 300 m of cable. This back-box version is mains-powered and has a built-in 25 mA bus supply for the sub-line (no Switch&Dim input – that is only on the DES version).
