Air damper actuators

GDB...1

GLB...1

Rotary version, AC 24 V / AC 230 V

• Electronic motor driven actuators for three-position and modulating control

• Nominal torque 5 Nm (GDB), 10 Nm (GLB)

• Mechanically adjustable span between 0...90°

• Pre-wired with 0.9 m long connection cables

• Type-specific variations with adjustable offset and span for the positioning

signal

• Position indicator

• Feedback potentiometer

• Self-adaption of rotational angle range and adjustable auxiliary switches for

supplementary functions

This data sheet provides a brief overview of these actuators. Please refer to the Tech-

nical Basics in document Z4634en for a detailed description as well as information on

safety, engineering notes, mounting and commissioning.

Use

• For damper areas up to 0.8 m

(GDB) / 1.5 m

(GLB), friction-dependent.

• Suitable for use with modulating controllers (DC 0...10 V) or three-position controllers

for air dampers or air throttles.
