Additional specifications and description
Minimum air resistance
This circular damper can be used in combination with standard circular ducts with a diameter of 125 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.
Reduced installation time
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.
If Modbus RTU communication is not available, the damper blade position can be controlled via a 0-10 Volt signal. In that case, the analogue input signal can be connected via the terminal block. The 24 Volt supply voltage can also be connected via this terminal block. Make sure not to connect the supply voltage via the terminal block and via the RJ45 socket simultaneously!
Easy 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.
Plastic enclosure
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.
