Desigo® Room Automation Room Automation Station, BACnet/IP, AC 24 V DXR2.E17C... For buildings with room pressurization and fume hood control applications, leveraging the functionality and flexibility of Desigo Room Automation applications.
Features Programmable The DXR2... automation stations provide the infrastructure for system and application-specific functions and can be programmed. Compact series The compact build permits mounting in narrow spaces and on standardized DIN rails, and is particularly well suited for compact panels or plants with integrated panel. Plug-in terminal blocks Plug-in terminal blocks to easily exchange room automation stations.
Functions The selected application and its parameters as well as input and output configuration determine the room automation station's functionality. A detailed description of functionality is available in the ABT (Automation Building Tool) online help.
The internal KNX PL-Link supply cannot be operated parallel to external power supplies. The internal KNX PL-Link power must be switched off during the engineering phase for external power. This is typically the case if the 50 mA from the internal supply is not enough to supply all devices connected on the KNX PL-Link bus. Type summary Order numbers Worldwide (without US and Canada) Type Stock number Applications Inputs Outputs DXR2.

DC 0…10 V outputs The DC 0…10 V outputs supply max. 1 mA. AC 24 V supply for field devices (V~) Actuators (valves, dampers) and active sensors are supplied directly by the device. Separate AC 24 V power supply is only required if field devices consume more than 5 VA. DC 24 V power supply for field devices (V+) Actuators (valves, dampers) and active sensors are supplied directly by the device. A separate DC 24 V field supply is only required if field devices use more than 2.4 W.
9205J01 Terminal cover Break off the cable inlets to insert the cables to the room automation station. To take off the terminal cover: Operation The outputs have no electricity when power fails. USB communications that does not work points to improper grounding of AC 24 V operating voltage (connection ⏊ must be grounded). Disposal The device is considered an electronic device for disposal in accordance with the European Guidelines and may not be disposed of as domestic garbage.
