rotary versions, AC 24 V

Electromotoric rotary actuators for 3-position or modulating control, nominal

torque 5 Nm (GDB) or 10 Nm (GLB), mechanically adjustable span from 0...90°.

Cable connections via terminals (type J) or connectors (type L).

Specific versions with adjustable starting point and span for the positioning sig-

nal, with position indicator and self-adaptation of the rotational angle range.

The present Data Sheet provides a brief overview of these types of damper actuators.

For a detailed description with information about safety, engineering notes, mounting

and commissioning notes, please refer to the document "Technical basics" (Z4634en).

Use

• For damper areas up to about 0.8 m

(GDB) and 1.5 m2 (GLB)

• Suitable for use with modulating controllers (DC 0...10 V) or 3-position controllers for

the control of air dampers or air throttles
