We offer an assembly service for the actuator with the fitting for this product. More information

Emergency Belimo SF actuator for HVAC dampers or ball valves (e.g., Giacomini R250D with adapter). The actuator is designed for damper sizes up to approx. 4m2. The actuator is controlled via a 0-10V signal. Communication is conducted via the Belimo MP-BUS. The actuator is suitable for integration into the Loxone system.

Functions

In the event of a power interruption, the return spring begins to rotate the actuator to its default position. For example, in the event of a power failure, it closes the damper or ball valve. The same can be achieved in reverse, depending solely on the initial position of the damper.

• The actuator can be manually operated using a locking button and a manual crank. 
• Optional control parameters: Open/close, 3-point, DC 0.5 - 30V.

Features

• The actuator is protected against overload, no end stops are required.
• Simple mounting on the damper shaft using a universal bracket.
• Adjustable working angle with mechanical stop.
• The actuator can be equipped with auxiliary switching contacts S...A or a feedback potentiometer.

Connectivity with the LOXONE smart home system 

The connection with the Loxone system is realised through the Belimo MP-Bus interface. To connect, you will need the product Loxone - Belimo Tree. Belimo Tree is an interface allowing the connection of up to 16 Belimo MP-Bus devices. Thanks to the native integration of MP-Bus, Belimo products become a direct part of Loxone Config and Miniserver, ensuring easy configuration and management. Belimo Tree significantly simplifies the connection of Belimo devices with the Loxone system, enabling quick and error-free setup of all functions. Its compact design and wide compatibility make this interface an ideal choice for modern and efficient building automation.
