Inlet pressure range:
1 to 12 bar (the inlet pressure must always be at least 1 bar above the regulated pressure
Outlet pressure range:

~ 100 mbar. (Factory set up)
Air consumption at constant control signal:
24 V DC ± 15% (Max. ripple 1 V)
Max. 6 W with 24 V DC and constant changes of the control signal ; < 1 W without change of control signal
Analog 0 - 10 V Impedance: 10 k W
Analog 4 - 20 mA Impedance: 0.5 k W
Outlet sensor signal:
A) proportional pressure outlet signal 0 - 10 V from integrated sensor (recomended load resistance 10 k
B) proportional pressure outlet signal 4 - 20 mA from integrated sensor (recommended load resistance 0.5 k
C) "Alarm" output signal 0/24 V with adjustable triggering level.
(Difference between control signal and sensor pressure signal) (Imax. = 40
- factory set up: diff. signal = ± 0.8 V to ± 1 V
- possible set up: diff. signal = ± 0.1 V to ± 5 V
To neutralize the alarm output signal during the control signal changes,
the use of a synchronized time lag relay is required.
Indicative response time:

2 to 4 bar - 2 to 8 bar
Step response: ~ 60 ms - ~

Step response: ~70 ms -
In case of control failure or if it is less than 1% of its full scale
value, the regulated pressure drops automatically to 0 bar (atmospheric
pressure). In case of voltage suply failure, the regulated pressure will
be kept constant (with eventual discrepancy due to loss of pressure in the
4 screw terminals under the protection cover with Pg 13.5 cable gland or
through DIN 43651 connector (6 P + E).
> 50 Mio changes of control signal steps.
Attention: It is compulsory to set the control signal at 0 V or 4
mA each time the air pressure supply is turned off (during the night or
the weekend). When the air pressure supply cannot be fully exhausted,
it is necessary to assure that the deviation between
the control value and the inlet pressure remains smaller than 1 bar.
