The EDA2 is an in-wall master dimmer touch panel engineered for two-channel management across any standard DALI lighting system. Compliant with the international DALI digital addressable lighting interface protocol IEC62386, this touch panel dimmer sends switching and dimming commands directly over the 2-wire DALI signal bus. Operating without an external line-voltage transformer or auxiliary power wire, the unit draws a nominal 6mA static current directly from the 16V DC bus. Two responsive capacitive touch keys provide dedicated control over two separate lighting circuits, downlights, or runs of single color LED strip lights. Each key supports dual actions: a rapid tap toggles fixture power on or off, while a continuous press ramps brightness smoothly up or down. With hardware rotary switches for instant physical addressing, the EDA2 delivers robust lighting DALI system integration for architectural interiors.
Features two dedicated capacitive touch keys that manage two separate DALI light channels, groups, or scenes independently.
Adheres to international DALI standard protocol IEC62386 to guarantee interoperability with certified DALI drivers and ballasts.
Pulls power directly from the 16V DC DALI signal line with a low static draw of 6mA, eliminating extra high-voltage wiring.
Enables unicast, group, scene, and broadcast operational modes selectable directly via rear rotary dials.
Includes onboard rotary spin switches X (0 to 9) and Y (0 to F) for physical address configuration without software tools.
Measures 86×86×37 mm, designed for flush installation into standard European and 86-type electrical back boxes.
Equipped with dual LED indicator lights on the front glass face to signal active channel output and feedback.

Q: Does the EDA2 touch panel dimmer require a separate 12V or 24V power supply?
A:No. The EDA2 is powered directly from the standard 16V DC DALI bus line, drawing 6mA of static current. It does not require external low-voltage power adapters or AC line voltage.
Q: What is the difference between EDA1, EDA2, EDA3, and EDA4 models?
A:The models differ strictly by the number of touch control keys: EDA1 controls 1 channel, EDA2 controls 2 channels, EDA3 controls 3 channels, and EDA4 controls 4 channels.
Q: How does the short press and long press operation work?
A:A short press (under 0.5 seconds) on either touch key toggles the assigned fixture ON or OFF. A sustained long press ramps the light level continuously upward or downward.
Q: How do the rear rotary switches configure unicast addressing?
A:Switch X represents tens (0–6) and switch Y represents units (0–9, continuing A–F). The initial channel address equals X*10 + Y. For example, setting X to 4 and Y to 0 assigns the controller to DALI address 40.
Q: Can the EDA2 control DALI group and scene modes?
A:Yes. Turning rotary switch X to position 7 sets group mode, and position 8 sets scene mode. Dial Y then designates the target group number (0–15) or scene number (0–15).
Q: What happens if unicast address calculation exceeds 63?
A:According to the IEC62386 standard, the maximum unicast address is 63. If your rotary combination totals a value beyond 63, the internal microcontroller defaults the address to 63.
Q: Is the DALI bus wiring polarized when connecting to the EDA2 terminal block?
A:Standard DALI control signals are non-polarized. You can attach the two bus wires to either terminal on the EDA2 rear socket without risk of connection faults.
Q: What size back box is needed for wall mounting?
A:The EDA2 has an 86×86 mm outer frame with a 37 mm total depth, fitting standard European 86-style flush-mount wall junction boxes.
