General

Siemens Rotary damper actuators are used in ventilation and air conditioning plants to regulate and shut off air dampers:

• For damper areas up to approximately 4 m2 (Guideline: Always comply with the damper manufacturer's specifications).
• Suitable for use with 2-position and 3-position controllers as well as modulating controllers (DC 0/2…10 V) to control air dampers.
• We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3 point control to ensure continuous and accurate operation.

Features

• With self-centering shaft adapter for shaft dia. 8...20.5 mm, square 8...14.5 mm, min. shaft length 20 mm
• With position indication and adjustable mechanical limit stop
• Button for disengaging the gear train to enable manual control
• With housing made of die-cast aluminium and 0.9 m connecting cable
