32 Nm Damper Actuators – RA32 Series

• Torque: 32 Nm, suitable for dampers up to 8.0 m².
• Control Signals:
  • On/off (two-position) or 3-point floating (RA32 24D, RA32 220D).
  • Selectable analog signals: 0-10 Vdc or 4-20 mA (RA32 24VC).
• Auxiliary Switches: Equipped on both digital models (e.g., RA32 24D S2) and analog models (e.g., RA32 24VC S2).
• Feedback Signal: Standard on all models with analog control signals (0-10 Vdc).
• Position Indicator: Integrated for real-time damper position monitoring.
• Manual Override: Push-button functionality for manual adjustments.
• Direction of Rotation: Adjustable via a switch on the PCB.
• Running Time: 220 seconds for all RA32-series models.
