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, and 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 luminaires

  • 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, defined in IEC 62386, ensures interoperability of electronic 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, published under IEC 62386, not only defines control gear but also specifies 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 luminaires and lighting groups. Assigning luminaires to operating elements and grouping is performed using short addresses. A DALI master can control a line with up to 64 devices, each assignable to 16 groups and 16 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 adapt 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®.

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 control and complex constant-light regulation — via centralized or decentralized systems.

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 reliably transmitted to the lighting system.

DALI Multi-Master Module
(Item No. 753-647)

The 12 mm-wide DALI Multi-Master Module (Item No. 753-647) is certified to the DALI-2 standard IEC 62386 and supports up to 64 DALI actuators (electronic control gear) as well as up to 16 multi-sensors (maximum of 64 sensor addresses). This eliminates the need to sensor-only parallel buses for brightness measurement and/or motion detection — saving both time and money. Commissioning and management of DALI networks have also been significantly simplified. Installation time is reduced, and the network structure is clearer — making DALI use more cost-effective than ever.

Each DALI actuator can be assigned to 16 groups and 16 scenes. The DALI Multi-Master Module also offers 16 additional virtual groups on the DALI bus.

Your Benefits:

  • Certified to DALI-2 Standard IEC 62386

  • Up to 64 DALI addresses for operating devices (ECGs) and control devices (sensors)

  • Freely programmable for complex applications

  • Interfaces between DALI and KNX®, BACnet®, Modbus® and others (in combination with the respective WAGO controllers)

DALI Power Supply
(Item Number 753-620)

WAGO offers two options for supplying DALI modules, allowing customers to choose the most cost-effective solution. A 12 mm-wide module (DALI Multi-Master DC/DC Converter, Item No. 753-620) is recommended for a single DALI module with 200 mA. If several DALI modules are operated on one controller, an external 230 V power supply for DIN-35 rail with an output current of 1100 mA (Switched-Mode Power Supply, Item No. 787-1007 for DALI Multi-Master Modules Item No. 753-647) is the ideal choice.

Your Benefits:

  • Cost-effective power supply for parallel operation of multiple DALI Multi-Master Modules

  • Power supply for the DALI Multi-Master Module: 787-1007 Switched-Mode Power Supply

DALI Configurator

The free DALI Configurator is a graphical interface for configuring and commissioning the DALI Multi-Master Module (Item Number 753-647) and the DALI network. The configurator is available as a stand-alone Windows application or for use with WAGO-I/O-CHECK software. It provides the following functions: easy commissioning, configuration, service, support and maintenance of a DALI network.

Key features of the software include a simplified project overview, optimized device addressing, efficient batch processing, and comprehensive data backup and restore functionality.

Your Benefits:

  • Simple and easy start-up/configuration of a DALI line

  • Efficient batch processing of a large number of DALI devices by multiple selection

  • Comprehensive data and parameter backup and restoration of a complete DALI line
