Circular motorised damper | 160 mm
Product description
A motorised damper is a device used in heating, ventilation, and air conditioning (HVAC) systems to regulate air flow inside of ductwork. Dampers are crucial for regulating the airflow to different parts of a building, ensuring proper temperature control and energy efficiency.
This damper is specifically designed to fit into ducts with 160 mm diameter and its supply voltage is 24 VDC, PoM. The damper blade position can be set via a 0-10 V signal or via Modbus RTU communication. Modbus RTU communication can be used to change the minimum and maximum position.
To stop the air leak, the airtightness of the enclosure and the damper blade needs to be ensured. Leakage can reduce the efficiency of the controller, increase the noise levels and can also lead to drafts and discomfort for occupants. For that, the damper blade provides class 4 airtightness and the enclosure's airtightness, which is classified as class D by EN1751.
This circular damper has the ability to regulate airflows with velocities between 0 and 10 m/s. An electric motor is installed in the damper to enable automated control. Usually used in HVAC systems, these dampers control airflow for both heating and cooling purposes.
Additional specifications and description
How does this circular damper help improve duct system efficiency?
This circular damper can be used in combination with standard circular ducts with a diameter of 160 mm. The circular ducts can be inserted inside the damper. To guarantee the airtightness of the system, the transition between duct and damper must be sealed with aluminum tape. The damper does not cause extra air resistance because the ducts can be slid into the damper. This increases the efficiency of the complete duct system and minimises energy losses.
How to connect?
One RJ45 connector is all it takes to connect this motorised damper! The built-in actuator requires a 24 VDC supply voltage. Modbus RTU communication and 24 VDC supply voltage can be connected via one UTP cable - we call it Power over Modbus or PoM. The damper blade position can be controlled via Modbus RTU communication. To facilitate wiring, we recommend to use the Sentera 24 VDC power supplies with RJ45 connector. These power supplies offer protection against short circuit, overload and overvoltage. A 24 VDC supply voltage increases the safety and reliability of your installation.
How to control the blade?
How to control the blade?
The damper blade position can be controlled via a 0-10 Volt signal or via Modbus RTU communication. That means that this motorised damper can be used in combination with all Sentera HVAC sensors that have a 0-10 Volt output. The 0-10 Volt signal can be connected via the terminal block. The 24 Volt supply voltage for the motorised damper can be connected via the terminal block or via the RJ45 socket. Make sure not to connect the supply voltage via the terminal block and via the RJ45 socket simultaneously!
Why is it simple to use?
This motorised damper doesn't require configuration. Once installed, it is ready to use. The default settings will do for most applications. If necessary, the settings can be adjusted via Modbus RTU communication. For example, the minimum and maximum damper blade position can be adjusted via the parameter settings. The Modbus register map provides a complete overview of all adjustable settings.

What makes the enclosure reliable?
The damper enclosure is made of high-quality r-ABS plastic. This material is exceptionally heat resistant, very tough and offers good protection against impacts.
