DALI Relay Module, Bus Powered SR-2701S

The SR-2701S is a mini DALI relay module. It brings loads without a DALI input into a DALI system and switches them on and off. It can also control a standard contactor.

It is powered by the DALI bus, so no extra power supply is needed. It gets one DALI address from the DALI master controller and works with DALI systems and controllers from other brands.

It switches 100-240VAC loads up to 500W at 110VAC (1000W at 230VAC) for incandescent, halogen and transformer loads, and up to 150W at 110VAC (300W at 230VAC) for LED and other capacitive loads. It can also switch 12/24VDC loads.

Key Features

• DALI relay module for on and off switching
• DALI bus powered, less than 3mA, no extra power supply
• 1 DALI address, set by the DALI master controller
• Switches AC loads up to 250V and DC loads up to 30V
• Incandescent, halogen and transformer loads: 500W @ 110VAC, 1000W @ 230VAC
• LED and capacitive loads: 150W @ 110VAC, 300W @ 230VAC
• Can control a standard contactor for bigger loads
• Mini size, fits into a standard wall box
• IP20, 5 year warranty

Typical Applications

Switching non-DALI lights, fans or other loads from a DALI or KNX-DALI system, or driving a contactor for larger circuits.
