Precise Sun Protection Control with ABB JRA/S 2.230.1.1 KNX Actuator
The ABB JRA/S 2.230.1.1 (2CDG110120R0011) offers a specialized solution for automating motorized window coverings. Primarily, this DIN-rail device bridges the gap between the KNX bus and 230V AC motors. Consequently, it grants users total control over natural lighting and privacy in any smart building.
Key Features and Functional Benefits:
  • Automatic Travel Detection: This model features a standout ability to detect motor travel time automatically. Furthermore, this function ensures accurate blind positioning even after thousands of cycles. As a result, you save time because the system eliminates the need for manual recalibration.
  • Independent Dual Channels: The device manages two separate outputs. In addition, mechanical interlocks protect each channel by preventing simultaneous UP and DOWN commands. Therefore, the actuator safeguards your motors against accidental electrical damage.
  • Manual Override & Visual Feedback: Moreover, the front panel provides manual operation buttons for each channel. Specifically, these buttons allow technicians to test the blinds during construction without a programmed KNX bus. At the same time, status LEDs show immediate feedback regarding the current movement.
  • Advanced Safety and Scenes: Additionally, the actuator supports complex safety functions like wind, rain, and frost protection. Consequently, the system automatically retracts the blinds during extreme weather to prevent damage. Finally, users can integrate the device into various “scenes” to automate morning and evening routines.
  • Efficient Energy Usage: The KNX bus powers the device directly. Moreover, by optimizing the angle of the blind slats, the actuator reduces the cooling load of the building. Accordingly, it contributes significantly to the overall energy efficiency of the HVAC system.
