Functions
Type
GDB.3..1 / GLB.3..1
GDB16..1 / GLB16..1
Control type
Three-position control
Modulating control
Positioning signal with adjustable
characteristic function
Y = DC 0...35 V at
Offset Uo = 0...5 V
Span U = 2...30 V
Rotary direction
Clockwise or counter-clockwise direction depends...
…on the type of control. With no power applied,
the actuator remains in the respective position.
...on the setting of the rotary direction DIL 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 propor-
tional to the rotary angle. U depends on the rotary
direction of the DIL 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°.
Self-adaptation of linear span
When self-adaptation is active, the actuator automat-
ically determines the mechanical end positions of the
linear span and maps the characteristic function (Uo,
U) to the calculated linear span.
Manual adjustment
The actuator can be manually adjusted by pressing the gear train disengagement button
Rotary angle limitation
The rotary angle of the shaft adapter can be limited mechanically with a socket head cap screw.
Ordering
Potentiometer and auxiliary switches cannot be added in the field. For this reason,
order the type that includes the required options.
Accessories to functionally extend the actuators are available, e.g., rotary/linear sets,
see data sheet N4698.
