The EAE SD110 KNX 1–10 V Dim Actuator is a high-density DIN-rail module for analogue dimming of fluorescent ballasts, ECGs, and LED drivers from KNX. It provides 10 independent channels, each with a 1–10 V dimming output and an integrated 16 A relay for complete load disconnection — eliminating standby consumption when lights are off.

Each channel is fully parameterized in ETS4/ETS5 and offers local membrane-switch manual control for commissioning and testing. The SD110 is bus-powered and does not require an additional auxiliary supply, simplifying distribution-board wiring.

Key Features — 10 × 16 A 1–10 V Dimming

Channel Outputs

• 10 channels: Independent 1–10 V dimming outputs, each with integrated relay.
• 16 A relay per channel: Complete switch-off of the load — zero standby loss when off.
• 1–10 V interface: Standard analogue dimming for ballasts, ECGs, and compatible LED drivers.
• Manual override: Membrane switches on the enclosure for each channel.
• Bus-powered: No external auxiliary power supply required.

Per-Channel Functions (ETS)

• Staircase: Timed auto-off for circulation areas.
• Scene: Integration into KNX lighting scenes.
• Operating hour: Runtime counting for predictive maintenance.
• Forced operation: Override mode for emergency or maintenance.
• Recovery behaviour: Configurable state after bus voltage return, failure, or ETS download.

Applications and KNX Integration

• Commercial office lighting: Dim banks of 1–10 V fluorescent or LED gear from KNX presence detectors and light sensors.
• Energy efficiency: Relay disconnect per channel removes standby draw from drivers when off.
• Phase dimming alternative: For trailing/leading-edge dimming of incandescent, halogen, or phase-dimmable LED, use the EAE UD106 Universal Dimmer Actuator.
• On/off loads: For pure switching without dimming, pair with or substitute using the EAE SW108 Switch Actuator.
• DALI installations: For DALI luminaire control, use an EAE DA100 or DA110 DALI Gateway instead.

Choosing EAE Dim Actuators

The SD110 suits projects with 1–10 V gear and high channel density (10 circuits in one module). The UD106 handles phase dimming with advanced fault detection and channel grouping for higher VA loads. Both are bus-powered and mount on standard DIN rail.
