Actuators with Multifunctional Output

Replacement for N° 70201-70203 KNX S1R-UP 230 V

Actuators KNX S1R with integrated façade control have a multifunctional output which can connect to either a drive with Up/Down control (blinds, awnings, shutters, windows) or two switchable devices (On/Off for light and ventilation). Because the output is designed to be free of potential, other systems can also be controlled, e.g. via the manual switch input on a motor control unit.

Automation can be specified externally or internally. Internally, there are numerous options available for blocking, locking (e.g. master-slave) and priority definitions (e.g. manual-automatic). Scenes can be saved and called up via the bus (scene control with 16 scenes per drive).

The KNX S1R-B4-UP and KNX S1R-BA2-UP models are equipped with inputs which are used as bus inputs (buttons, alarms, etc.) or for T-NTC temperature sensors. The KNX S1R-UP model does not have any analogue/digital inputs.

N° 70513 S1R-BA4-UP, 4 A/D Inputs

  • KNX S1R-UP (70511) KNX S1R-UP (70511)
  • KNX S1R-BA2-UP (70512) KNX S1R-BA2-UP (70512)
  • KNX S1R-BA4-UP (70513) KNX S1R-BA4-UP (70513)
  • Free of potential multifunctional output for a 230 V drive (shading, windows) or connection of two switchable devices (light, fan)
  • Relays switch with low wear near the zero-voltage transition
  • Inputs for binary contact or temperature sensor (not on KNX S1R-UP)
  • Automatic runtime measurement of the drives for positioning (incl. fault reporting object)
  • Position feedback (movement position, also slat position for shutters)
  • Position storage (movement position) via 1-bit object (storage and call-up e.g. via buttons)
  • Parameters for taking drive and mechanics downtimes into account
  • Control via internal or external automation functions
  • Integrated shade control with slat adjustment for shutters based on the position of the sun
  • Scene control for movement position with 16 scenes per drive (also slat position for shutters)
  • Mutual locking of two drives using zero position sensors prevents collisions e.g. of shade and window (master–slave)
  • Blocking objects and alarm reports have different priorities, so safety functions always take precedence (e.g. wind block)
  • Manual or automatic priority setting via time or communication object
  • 4 temperature switching outputs in the application program with adjustable threshold values (presetting the parameters or communication object)
  • Brief time limit (movement command blocked) and 2 movement limits
  • Configuration is made using the KNX software ETS
