Somfy RS485 (SDN) 2-Way Module for Glydea ULTRA

The Somfy RS485 / SDN 2-Way Module is a hardwired hardware expansion that integrates Glydea ULTRA 35 DCT and 60 DCT motors into the Somfy Digital Network (SDN) topology. Built exclusively for commercial builds, high-end automation projects, and luxury smart homes, this module swaps out wireless mesh vulnerability for rock-solid, physical low-voltage data lines.

Product Specifications

Dual-Source Bus Power: Electrically handles its data layer via the SDN bus line while extracting secondary power straight from the host motor.

Standardized RJ45 Data Ports: Utilizes industry-standard CAT-5e or higher TIA-568B pinouts to carry serial RS485 differential signals without data drops over hundreds of feet.

Transmits precise real-time positions back to the central processor, enabling micro-adjustments for precise solar tracking and glare control.

Zero-Latency Response: Processes network commands instantaneously with absolute immunity to RF congestion, wireless interference, or structural concrete blockades

Functional Design Highlights

16 Unique Group Addresses: Each single physical module can be assigned up to 16 different SDN group channels simultaneously.

Complex Scene Matrixing: Simplifies massive window expanses by allowing one motor to simultaneously respond to localized wall keypads, whole-floor triggers, and global building-wide fire/emergency overrides

Safeguards soft start / soft stop velocity damping and programmable intermediate "my" custom positions.
