Functions
Type
GDB.3..2 / GLB.3..2
GDB16..2 / GLB16..2
Control type
Three-position control
Modulating control
Positioning signal with ad-
justable characteristic func-
tion
DC 0...35 V at
Offset Uo = 0...5 V
Span U = 2...30 V
Linear travel direction
The direction of linear travel depends on...
…the type of control. With no power ap-
plied, the actuator remains in the respec-
tive position.
...the DIL switch setting outward / inward.
Position indication
Position indicator: Output voltage
U = DC 0...10 V is generated proportional
to the linear travel. U depends of DIL
switch setting.
Auxiliary switch
The switching points for auxiliary switches A and B can be set independent of each
other in increments of 3.4 between 3.4 and 57.1 mm.
Self-adaptation of linear
span
When self-adaptation is active, the actua-
tor automatically determines the mechani-
cal end positions of the linear span and
maps the characteristic function (Uo, U)
to the calculated linear span.
Linear limitation
Stepless limitation between 0 and 60 mm for the linear travel is possible
by means of a clamp from the linear/rotary set ASK55.2
