What the Rako RACUB is
The Rako RACUB is a dual-relay switching module for motor control, suitable for mains, low-voltage and dry-contact motors. It is the most flexible of Rako's three wireless curtain modules: the RACUB2L is for mains motors with two live inputs, and the RACUB24DC is for 24V DC polarity-reversing motors.
Where it sits in a Rako system
The RACUB is controlled by Rako wireless commands from keypads such as the RK-EOS-6, and works with the Rako app through an RK-HUB. Basic set-up can be done from a Rako keypad; full customisation, including relay time-out and latching or momentary switching, uses RASOFT Pro with a RAMPI or RK-HUB. See all Rako wireless blinds and curtains.
