The 2-Channel Blinds Controller is a DALI-compatible interface unit that allows control of blinds and curtains in a DALI 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 unit has 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 relaystate indicator LEDs are illuminated when the respective relay is closed.
