  • Distribution module sends power and data to shade and drapery motors
  • Powers and controls between 1 to 4 low-voltage RS485 motors
  • Program up to 16 intermediate positions per motor
  • Offers a control for groups of motors with stop and align command
  • Easy to connect/disconnect RJ45 and 4 pin ports with adaptor cable included
  • Safe operation and industry-standard compliance (UL 2108/ UL 1310)

The device supports both Somfy Synergy™ API and CoAP Digital Building API compatible with Molex Transcend Network Connected System. When operating motors in a group, motors will cascade individually. Compatible Somfy motors include: Sonesse® 30 RS485 DC, Sonesse® 50 Ultra DC RS485, Irismo™ 35 DC RS485.

Somfy Digital Network™ (SDN): Intelligent Wired Shading

Install robust, cost-efficient, and powerful shade controls with Somfy Digital Network (SDN) devices. Designed specifically to provide intelligent motors and controls for large scale shading projects, the SDN system offers a professional-grade solution to creating an interconnected home of intelligent devices.

SDN technology is based on standard network architecture that transmits digital signals over a twisted pair bus line. It uses the RS-485 standard with Category 5 UTP cable, Ethernet patch cables, RJ45 connectors and splitters for communication between devices.

SDN System Benefits

  • Differential signaling, low data speed communication and high impedance devices
  • Single bus segment can be up to 4,000 feet with 255 devices
  • Free wiring topology with no termination resistors
  • Noise and interference is minimized by using capacitance controlled, unshielded twisted pair cable
  • System scalability is virtually unlimited
  • No need for special wire or connectors
  • Bus-connected control devices are powered directly from the bus line using a 24VDC class 2 power supply
