The Rako RACUB-24DC is a curtain and blind module for use with 24V motors requiring polarity reversing control. Rako 0907-S curtain and blind control units allow control of most blind and curtain motors. The 0907-S has two change over relay outputs. The 0907-S requires a 24V DC supply. The units are controlled using either the Rako single or 8 channel switches and/or transmitters. The wall switches and hand-held transmitters communicate with the units using coded FM radio control signals.
