The 2-Channel 490 Blinds Controller is a DALI-compatible interface unit that allows control of blinds and curtains in a DIGIDIM lighting control system. The blinds controller is a DIN-rail mounted unit that provides two independent control channels, each with two single-pole, volt-free contacts for switching up to 550 W up/down or power direction motors from a DIGIDIM system.

The blinds controller is provided with a status LED, a physical selection switch and relay-state indicators. The status LED provides status and a fault indication. The physical selection switch is used to identify the device during system configuration. The relay-state indicator LEDs are illuminated when the respective relay is closed.

Note: This unit does not contain a DALI power supply. Therefore, one must be incorporated elsewhere in the system.

  • Up/Down mode operates in a ‘Break before Make’ manner to prevent motor damage.
  • Relays are internally isolated permitting separate mains phases to be controlled in one unit.
  • All DALI functions are programmed with DIGIDIM Toolbox software.
  • DIN-rail mounted and only 88 mm wide.
