9.1.2 Output
Compressed air output
Range 0 ... 6 bar (0 ... 90 psi)
Air capacity
5.0 kg/h = 3.9 Nm
3
/h = 2.3 sfcm
at 1.4 bar (20 psi) supply pressure
13 kg/h = 10 Nm
3
/h = 6.0 sfcm
at 6 bar (90 psi) supply pressure
Output function For single or double-acting
actuators, air is vented from
actuator or actuator is blocked in
case of (electrical) power failure
Shut-off values
End position 0 % = 0 ... 45 %
End position 100 % = 55 ... 100 %
Digital output (control circuit to DIN 19234 / NAMUR)

Switching state logical "0"
Current > 2.1 mA
Switching state logical "1"
Effective direction (configurable)
normally logical "0" or logical "1"
9.1.3 Travel
Rotation angle
Used range 25 ... 120° (rotary actuators,
optional 270°)
25 ... 60 ° (linear actuators)
Travel limit Min. and max. limits, freely
configurable between
0 ... 100 % of total travel (min.
range > 20 %)
Travel time prolongation Range of 0 ... 200 s, separately
for each direction
Dead band time limit Setting range 0 ... 200 s
(monitoring parameter for
control until the deviation
reaches the dead band)
9.1.4 Air supply
Instrument air free of oil, water and dust to DIN/ISO
8573-1. Pollution and oil content
according to Class 3 (purity: max.
particle size = 5 µm, max. particle density
= 5 mg / m
3
; oil content: max.
concentration = 1 mg / m
3
; pressure dew
point: 10 K below operating temperature)
Supply pressure 1.4 ... 6 bar (20 ... 90 psi)
IMPORTANT (NOTE)
Do not exceed the maximum operating pressure of the
actuator!
Air consumption < 0.03 kg/h / 0.015 scfm (independent
of supply pressure)
