SR-DARM16-DIN4 DALI-2 Switching module 4×16 A

The Sunricher SR-DARM16-DIN4 is a DALI-2 certified 4-channel relay module for DIN rail installation, designed for switching electrical loads via a DALI system. It allows devices without a native DALI interface to be integrated into a DALI installation and switched on and off through DALI control.

The module features 4 independent volt-free relay outputs, with each channel capable of switching loads up to 16 A. The relay contacts are NO (Normally Open) and are open in their default state.

Thanks to the volt-free contacts, independent external circuits can be switched. The outputs support switching voltages up to 250 V AC or 30 V DC and are suitable for resistive, capacitive and inductive loads.

Each of the four relay channels can be controlled independently via DALI. The module uses 4 DALI addresses, which can be automatically assigned by a compatible DALI Master Controller.

The relay outputs feature zero-crossing detection, helping to reduce stress on the relay contacts when switching AC loads and extending relay service life.

The SR-DARM16-DIN4 is powered by 100–240 V AC, 50/60 Hz and is designed for installation on a standard 35 mm DIN rail.
