ESYLUX Introduces APC Ethernet Link for Building-Wide DALI-2 Lighting Control

ESYLUX has expanded its DALI-2 lighting control portfolio with the APC Ethernet Link, a compact communication module that enables building-wide networking of up to 16 DALI-2 control lines. The solution allows facility managers and building operators to centrally switch lighting on and off, recall lighting scenes, manage groups, and implement cross-line swarm functionality while maintaining the familiar configuration workflow through ESYLUX DALI-2 Application Controllers (APCs).

A single ESYLUX DALI-2 Application Controller already supports up to 16 groups and 64 control devices, making it suitable for large building areas. With the APC Ethernet Link, multiple APC-controlled DALI-2 lines can now be interconnected, providing centralized management across entire buildings or campuses.

Each DALI-2 line is equipped with one APC Ethernet Link, which is installed either in the control cabinet or on the ceiling and connected via a CAT5 cable to an Ethernet switch. The module is powered through Power over Ethernet (PoE), either directly from a PoE-enabled switch or via an external PoE injector. Network configuration is performed automatically, simplifying installation and commissioning.

The APC Ethernet Link enables bidirectional communication between connected DALI-2 lines, supporting centralized on/off switching, scene activation, and advanced group management. This makes it possible to coordinate lighting scenarios across multiple areas, adapting building-wide illumination to changing room layouts or occupancy requirements.

The solution also extends ESYLUX’s swarm function across multiple DALI-2 lines. In this mode, occupied zones receive full illumination while unoccupied areas automatically dim to a comfortable background lighting level. When the building is completely vacant, lighting throughout the connected network can be switched off automatically, further reducing energy consumption.

All cross-line functions are configured using the existing ESYLUX DALI-2 Application Controllers, which are available either as integrated APC presence detectors or DIN rail-mounted APC modules. Push buttons and BMS presence detectors can be incorporated as input devices to support applications such as presence- and daylight-dependent constant light control as well as energy-efficient Human Centric Lighting (HCL) installations.

With the APC Ethernet Link, ESYLUX extends the scalability of its DALI-2 lighting control system, enabling intelligent, centralized management for larger buildings while preserving the flexibility and energy-saving capabilities of distributed lighting control.
