SR-2701S-DT7AC DALI-2 Switching module 1×4.3 A

The Sunricher SR-2701S-DT7AC is a compact DALI-2 certified Device Type 7 (DT7) relay module designed for switching electrical devices 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 1 relay output with a maximum switching current of 4.3 A. It is designed for switching 100–240 V AC loads and supports resistive, capacitive and inductive loads.

The SR-2701S-DT7AC uses 1 DALI address, which can be assigned using a compatible DALI Master Controller. It is compatible with DALI and DALI-2 systems and complies with IEC 62386-208 for DALI Device Type 7.

Integrated Zero Crossing Detection helps reduce inrush current when switching AC loads, reducing stress on the relay contacts and extending relay service life. The manufacturer specifies a relay lifetime of up to 300,000 switching cycles. The module also features overload and short-circuit protection.

Thanks to its compact dimensions, the SR-2701S-DT7AC is suitable for installation in a standard electrical mounting box, for example behind a switch or close to the controlled device.
