This circular motorised damper is suitable for ducts with 125 mm. The position of the damper blade can be set via Modbus RTU communication or a 0-10 V signal. The enclosure has an airtightness class D according to EN1751. To ensure this classification aluminium tape should be wrapped on the seam between damper/duct. The unit needs 24 VDC supply voltage. We recommend using Sentera 24 VDC power supplies with RJ45 connector. They are protected against overload, overvoltage and short circuit. Once installed the device is ready for use. The default settings will suffice for most applications. If you do need to change some parameters, this can be done via Modbus RTU communication.

This self-calibrating CO2 sensor measures CO2 as well as temperature, relative humidity and ambient light conditions. It needs a 24 VAC supply voltage. This sensor can also directly control an EC-fan, AC fan speed controller or frequency inverter. It has 1 single analogue / modulating output depending on the highest measured value for temperature, humidity or carbon dioxide. If you only want to use it for measuring CO2, you can deactivate the temperature or humidity measurement. The FCMFX-series are available for different types of supply voltages such as 24 VDC, 24 VAC/VDC or 230 VAC. All version have 3 LEDS on the frontpanel showing whether the measured value is within or out of range. Additionally they are available in a version with audible alert. All parameters are accessible via Modbus RTU. This sensor doesn't need to be configured. Once installed it's ready for use.
