SDN 0-10V Interface
The SDN 0-10V Interface control is a device that will accept industry standard 0-10V input and convert it to a Somfy Digital
Network™ (SDN) signal. The SDN signal will drive a Somfy RS485 motor to a percentage of opening or closing based
upon the 0-10V input level and the setting of the reverse push button.
• No configuration or programming required.
• Reverse operation by pressing and holding the reverse button for 1 second.
• One control can drive up to 20 SDN tubular motors.
• Provides 45 SDN Bus Power units

1. Verify that the limits of the RS485 motor are set and the power to the motor is applied.
2. Verify that the SDN 0-10V Interface is OFF, then connect the motor data cable and the 0-10V input according to Figure 1.
Do not connect the +24V power supply at this time.
*NOTE* VERIFY THE POLARTIY OF THE 0-10V POSITIVE (+) VIOLET AND NEGATIVE (-) GREY INPUTS BEFORE
APPLYING POWER.
3. Connect the +24V power supply to the 0-10V Control. Then verify that the Bus Power Supply LED on the Bus Out jack is
solid green. Also verify that the Bus Activity LED on the Bus Out port turns on for 2 seconds and then turns off.
4. Turn on the SDN 0-10V Interface and verify that the motor responds accordingly to various input levels.
If reverse operation of the motor is desired:
• Drive the motor to the fully opened or the fully closed limit
• Then press and hold the reverse button for 1 second
• Verify that the motor moves to the opposite limit
