What the Rako RACUB24DC is
The Rako RACUB24DC is a dual-relay module that controls 24V DC motors by polarity switching. For mains motors, choose the RACUB2L; for 12V DC or dry-contact motors, the RACUB.
Where it sits in a Rako system
The RACUB24DC 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.
