Couplers connect, extend or segment DALI systems and allow external control input, which enables larger, multi-zone architectures and integration with other technologies. They support flexible system design and easier expansion. The right devices depend on your system structure and integration needs. Share your layout and objectives and we can help select suitable couplers and interfaces.
Segmenting helps when a system has many devices or several zones, improving manageability, performance and scalability. Couplers let you divide and connect segments so they work together. We help plan the segmentation and select suitable couplers for the structure, so the system stays stable and easier to commission and maintain.
Yes. Couplers and control interfaces allow external control input and can support integration across zones or with other technologies. This helps lighting form part of a coordinated system. We support the lighting layer’s integration readiness rather than providing a full BMS. Share your integration objectives and we can advise on suitable devices.
The right couplers and interfaces let a DALI system scale, segment and integrate cleanly, supporting flexible, maintainable control architecture.
Segmentation
We help select couplers to divide larger systems into manageable, coordinated zones for stability and scalability.
Expansion
Guidance on devices that let DALI systems extend and connect, so the system can grow without redesign.
Integration
Advice on interfaces that bring external control into the system and support integration across technologies.
Architecture
Support planning a scalable, maintainable architecture using suitable couplers and interfaces.
Couplers and control interfaces connect, extend and segment DALI systems and allow external control input, enabling flexible, scalable control architecture and integration across zones or technologies. The range includes push-button couplers and interface modules. The right devices depend on the system structure, scale and integration requirements.
Devices that connect DALI networks and integrate manual or push-button control into the system.
Interfaces that allow external control input and integration.
Devices that divide larger systems into coordinated zones.
The right couplers and interfaces give a DALI system flexible architecture, easier expansion and cleaner integration across the building.
Coupler and interface selection depends on the system structure, scale and integration requirements. Share these details and we can help plan the architecture and select suitable devices, subject to confirming the full system.

The most useful details are the system structure and scale, the number of zones or segments, the devices involved, and any integration requirements. With this we can help select suitable couplers and interfaces for a scalable, coordinated architecture, and flag anything that needs checking. Sharing your layout and objectives helps us recommend the right devices.
By connecting, extending and segmenting DALI systems, couplers let a system grow and be divided into manageable zones without redesigning it from scratch. This supports scalability and maintainability. We help plan where segmentation and extension are needed and select suitable devices, so the system can adapt as the building’s needs change.
Control interfaces and couplers can allow external control input and support integration across technologies through DALI. This helps lighting coordinate with other systems. We support the lighting layer’s integration readiness rather than providing a full BMS. Sharing your systems and objectives lets us recommend suitable interfaces for a compatible integration.
Yes. We can provide datasheets and technical documentation to support selection and system design. Tell us the system or requirement and we can supply the relevant data or help identify suitable couplers and interfaces from your architecture and integration needs, supporting a scalable, reliable control system.
Yes. We supply couplers and interfaces alongside DALI power supplies, dimmers, relays and Tridonic components, so you can source a complete control system from one place. We help ensure the devices work together within a coherent architecture, supporting flexible, reliable control across the installation.
