This is a 2-DIN relay output module to control AC rollerblind motors. It has been developed to be connected to and controlled by the smart-house system controllers. The rollerblind motor is driven by two relays in series: one to switch the motor ON/OFF and the second one to control the direction UP/DOWN. These two relays are controlled in such a way to respect the motor timing before any reversing of the motor direction.
