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 optimizes switching of AC loads and helps reduce stress on the relay. 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.
