Desigo® Room Automation Compact 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 applicationspecific 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. Communication ● For critical environment DXRs with fume hood controls, all controllers in a pressurized space must be on a common switch. ● 2-Port Ethernet switch for cost-effective cabling via line topology.
Bus power supply The room automation station includes the bus power for KNX PL-Link. The bus power is switched on by default, but can be switched off via a web interface or configuration in the Automation Building Tool (ABT). 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.

Triac outputs AC 24 V Individual triac outputs may have a max. load of 12 VA, 24 V*0.5 A=12 VA. The following possibilities are permitted: ● Slow floating control actuators. ● Multiple motorized actuators with a total of max. 12 VA. ● 1 thermal actuator with 6 VA start load in a cold state. ● 2 thermal actuators with 12 VA start load each in a cold state. For transformer design (voltage drop), each thermal actuator must be counted at the full start load, since the triac outputs can be freely controlled.
