Smart Infrastructure 2019-11-28
Functions
Type GBB.3..1 / GIB.3..1 GBB/GIB16..1
Control type
Three-position control
(see “Use”)
Modulating control
Positioning signal with adjustable
characteristic function
DC 0...35 V at
Offset Uo = 0...5 V and
Span DU = 2...30 V
Rotary direction
Clockwise or counter-clockwise direction depends...
…the type of control. With no power applied, the
actuator remains in the respective position.
... the setting of the rotary direction switch
clockwise / counter-clockwise
Position indication: Mechanical Rotary angle position indication by using a position indicator.
Position indication: Electrical
The feedback potentiometer can be connected to
external voltage to indicate the position.
Position indicator:
Output voltage U = DC 0...10 V is generated
proportional to the rotary angle. U depends on the
rotary direction of the switch setting.
Auxiliary switch
The switching points for auxiliary switches A and B can be set independent of each
other in increments of 5° within 0° to 90°.
Powerpack
Mounting two of the same actuator types on the
same damper shaft results in a double torque (with
accessories ASK73.1).
Mounting two of the same actuator types on the
same damper shaft results in a double torque (with
accessories ASK73.2).
Rotary angle limitation The rotary angle of the shaft adapter can be limited mechanically at increments of 5°.
Ordering
Potentiometer cannot be added in the field. For this reason, order the type that in-
cludes the required options.
Individual parts such as position indicator and other mounting materials for the actuator
are not mounted on delivery.
Accessories to functionally extend the actuators are available, e.g., rotary/linear sets,
auxiliary switches (1 or 2 switches) and weather protection cover; see data sheet
N4699.
