DALI-2

Lighting control with DALI — the Digital Addressable Lighting Interface (DALI) is a communication protocol for building lighting applications. It enables communication between lighting control devices such as electronic control gear, brightness sensors, or motion detectors.

DALI system features:

Easy reconfiguration when changing room usage
Digital data transmission via two-wire line
Supports up to 64 single units, 16 groups, and 16 scenes per DALI line
Status confirmation of individual lights
Configuration data (e.g., group assignments, light scene values, fading times, emergency lighting/system failure level, power-on level) stored in the electronic control gear (ECG)
Flexible bus topologies: line, tree, star, or any combination
Cable lengths up to 300 meters (depending on cable cross-section)

DALI Explained Simply

The manufacturer-independent DALI standard is defined in IEC 62386 and ensures the interoperability of control gear in digitally controllable lighting systems, such as transformers and power dimmers. This standard replaces the commonly used analog 1–10 V dimmer interface.

The DALI-2 standard is published under IEC 62386. In addition to defining control gear, it also specifies the requirements for control devices — including our DALI Multi-Master Module.

Building Lighting Control: DALI-2 Applications

The DALI protocol is used in building automation to control individual lights and lighting groups. Assigning individual lights to operating elements and grouping is performed using short addresses. A DALI master can control a line with up to 64 devices. Each device can be assigned to 16 individual groups and 16 individual scenes. Thanks to bidirectional data exchange, not only switching and dimming but also status messages can be transmitted from the operating unit back to the controller.

DALI maximizes flexibility by enabling lighting control to be adapted to new conditions — such as changes in room layout or usage — via software, without requiring hardware modifications. Lighting assignments and groupings can also be adjusted after installation without rewiring. In addition, advanced DALI controllers can be integrated into higher-level controllers and connected to a complete building automation system via bus systems such as KNX ^®, BACnet, or Modbus^®.

Key Benefits:

Quick and easy installation of DALI lights using WINSTA^® Pluggable Connection System from WAGO
Freely programmable applications for maximum project flexibility
Connection of digital/analog sensors and actuators, as well as subsystems (e.g., DALI, EnOcean^®)
Certified to the DALI-2 standard (EN 62386)
“Easy mode” for lighting functions without complex programming

Flexible, Convenient Lighting Control: with WAGO and DALI-2

WAGO's I/O System effectively showcases your lighting — from simple switching and dimming to daylight-dependent lighting control and complex constant light regulation of the lighting system — via a centralized or decentralized system.

The product range includes the DALI Multi-Master Module and various power supplies. WAGO’s DALI Configurator enables straightforward commissioning and configuration of DALI network devices. WAGO also offers a wide selection of multi-sensors for motion and brightness detection.

Our DALI-2 products offer flexible lighting control solutions. Various controllers with different bus systems — such as BACnet, KNX ^®, or Modbus^® — and the extensive module portfolio of the I/O System meet diverse requirements and interconnect different building systems.

WAGO's WINSTA^® Pluggable Connection System enables scalable solutions for convenient lighting applications. DALI signals are distributed quickly, securely and without errors — and reliably transmitted to the lighting system.

DALI Products from WAGO

Compact Controller with DALI (Item Number 751-9403)

The WAGO Compact Controller 100 with DALI is the ideal solution for applications requiring integrated lighting control. It enables direct connection and control of DALI lights without an additional gateway.

The integrated DALI Multi-Master Module is certified according to the DALI-2 standard IEC 62386 and acts as a DALI application controller. In addition to controlling lights (electronic control gear), sensors such as presence or brightness sensors can be directly integrated. This eliminates the need for additional bus systems, keeping the entire DALI installation clearly structured and easy to maintain.

Key Benefits:

Direct connection to DALI lights without an additional gateway
DALI Multi-Master Module certified to DALI-2 standard IEC 62386
Compact solution for lighting automation
