SR-2701DIN-DT7 DALI-2 Switching module 4×12 A

The Sunricher SR-2701DIN-DT7 is a DALI-2 certified 4-channel DT7 relay module for DIN rail installation, designed for switching non-DALI electrical loads through a DALI lighting control system. With 4 independent 12 A relay outputs, the module allows conventional luminaires, power supplies, contactors and other electrical devices to be integrated into and controlled from a DALI system.

As a DALI Device Type 7 (DT7) relay actuator, the SR-2701DIN-DT7 provides reliable ON/OFF switching of resistive, capacitive and inductive loads. Each of the four channels supports loads up to 12 A or 2760 W at 230 V AC.

Each relay channel can be addressed and controlled independently. The module uses 4 DALI addresses, allowing individual switching of all four outputs through a compatible DALI or DALI-2 controller.

Integrated Zero Crossing Detection optimizes the switching point for AC loads, reducing stress on the relay contacts and helping to extend their operating life. This makes the module particularly suitable for professional DALI lighting installations with frequent switching operations.

The compact DIN rail design makes the SR-2701DIN-DT7 suitable for installation in electrical distribution boards in commercial buildings, offices, hotels, residential projects and other DALI lighting control applications.
