Compact Casambi controller for motorised curtains, roller blinds and venetian blinds, and for lighting loads. Two relay channels with up/down interlock and stop control drive AC three-wire tubular motors, or DC low-voltage motors through their control box, from an AC 100–240 V or DC 12–48 V supply. A wired switch input keeps existing wall switches in use, and the control mode is chosen in the Casambi app.
Key Benefits
Drives AC three-wire tubular motors, and DC low-voltage motors through their control box, for curtains, roller blinds and venetian blinds. Switch the same device to a lighting mode in the app to control lighting loads instead.
Up/down interlock keeps both directions from running at once, and a stop command halts the motor mid-travel. Relay, active or passive (voltage-free) output is selected in the Casambi app.
The wired switch input works with existing rocker or momentary switches, so retrofit projects keep familiar controls while gaining Casambi app control. Compact 44 × 44 mm body fits in a back box.
