Desigo™ Room Automation Compact actuating room automation stations, BACnet/IP, AC24 V (Actuating DXR) DXR2.E10PL-102B, DXR2.E10PLX-102B Combination room automation station and actuator for buildings with increased demands placed on functionality and flexibility in Room Automation applications, VAV, Dual Duct and FPB 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 directly on the damper shaft, and is designed for VAV and FPB. Plug-in terminal blocks Plug-in terminal blocks to easily exchange room automation stations. Integrated actuator The actuator gear base is integrated into the housing of the actuating DXR. For dampers requiring up to 88 lb-in (10 Nm) of torque.
Communication ● 2-Port Ethernet switch for cost-effective cabling via line topology. ● USB connection for service and commissioning, firmware download, and LAN access. ● The following functions are available with the KNX PL-Link bus: – Communication with room operator units, switches, sensors, actuators, and luminaires. – Plug-and-play connection of Siemens field devices with KNX PL-Link. – Integration of common devices using KNX S-Mode (ETS engineering required).

Triac outputs AC 24 V Individual Triac outputs may have a max. load of 12VA. The following possibilities are permitted: ● Internal floating control actuator. ● One or two motorized actuators with 6 VA each. ● 1 to 4 binary outputs with 12 VA load each. ● 1 or two thermal actuator(s) with 6 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.
Operation The outputs have no electricity when power fails. USB communications failure can be caused by weak or incorrect grounding at DXR 24 V power termination. (The power terminal labeled ⏊ must be connected to earth ground.) Disposal The device is considered an electronics device for disposal in terms of European Directive 2012/19/EU and may not be disposed of as domestic garbage. ● Dispose of the device through channels provided for this purpose.
