KNX S1R-B4-UP DES

Actuator for 1 Drive with 3 Limit Switches

 

  • KNX blind actuator for a motor with 2 end positions (lower limit switches)
  • Integrated automatic functions for shading/sun protection
  • 4 binary inputs for buttons, auxiliary contacts etc.

 

The Actuator KNX S1R-B4-UP DES is an electronic control device for controlling a motor with 3 end switches. A 230 V AC power supply is needed for the motor.


  • 1 drive output for a drive with 3 end switches (Venetian blinds with working position)
  • 4 binary input for use as manual or bus button
  • Position feedback of the movement position
  • Position storage (movement position) via 1-bit object (storage and call-up, e.g. by button)
  • Controls by internal or external automatics
  • Integrated shading control
  • Scene control for movement position with 16 scenes
  • Blocking objects and alarm messages have different priorities so that safety functions always have priority (e.g. wind blocking)
  • Manual or automatic control configuration per time or communication object

Configuration is made using the KNX software ETS 5
