8-Subnet DALI Controller (478)
8-subnet DALI Controller, suitable for controlling ballasts/
drivers when device addressing is not required. This reduces
commissioning and maintenance cost, as failed devices
can be simply replaced. The flexible control inputs support
multiple protocols, by routing an input address/group to its
corresponding subnet output.
Key Features
• Control using DALI Broadcast messages on each subnet
• Integral DALI Power Supply – supports up to 512 DALI
devices (2 mA per driver/ballast)
• Lamp failure reporting per subnet
• Lower commission costs - device addressing/grouping on
subnet not required
• DALI / S-DIM / DMX control inputs
