Wiring diagram

Luminaires, sensors and push buttons on two DALI-2 lines

Power, both DALI lines and both LAN ports sit on the bottom edge; the digital inputs, USB A and the USB-C service port are on top. The reference wiring shows a typical office with luminaires, sensors and push buttons split across both lines.

SYMPL dali Node

One more DALI line, connected over e:net

Need more than the two DALI lines of the DALI Duo SX? Add a SYMPL dali Node to the network. Each node brings one more DALI line for up to 64 ballasts and 64 input devices and connects to the DALI Duo SX over e:net on a standard Ethernet cable.

  • One DALI line for up to 64 ballasts and 64 input devices, with DALI bus power supply (max. 250 mA)
  • e:net over Ethernet, RJ45, 10/100 Mbit/s
  • Compact 3 unit housing for 35 mm DIN rails or wall mounting via key hole
  • External 24 V DC supply, 6.5 W
