Fluid
Lubricated or non lubricated air and neutral gases recommended filtration: 25 -
50 µ
Temperature range:
Ambient 0 to 50°C.
Fluid 0 to 50°C.
Inlet pressure range:
1 to 12 bar (the inlet pressure must always be at least 1 bar above the regulated pressure
value).
Outlet pressure range:
0.2 to 10 bar
Hysteresis:
~ 100 mbar. (Factory set up)
Linearity:
1% f.s.o.
Air consumption at constant control signal:
0.
Supply voltage:
24 V DC ± 15% (Max. ripple 1 V)
Power consumption:
Max. 6 W with 24 V DC and constant changes of the control signal ; < 1 W without change of control signal
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
W)
B) proportional pressure outlet signal 4 - 20 mA from integrated sensor (recommended load resistance 0.5 k
W)
|
C) "Alarm" output signal 0/24 V with adjustable triggering level.
(Difference between control signal and sensor pressure signal) (Imax. = 40
mA)
- 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:
With a volume of 330 cm³ at the outlet of
the regulator.
Filling:
2 to 4 bar - 2 to 8 bar
Step response: ~ 60 ms - ~
120 ms
Emptying: 4 to 2
bar - 8 to 2 bar
Step response: ~70 ms -
~-130 ms
Safety position:
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
servo-chamber).
Electrical connection:
4 screw terminals under the protection cover with Pg 13.5 cable gland or
through DIN 43651 connector (6 P + E).
Life expectancy:
> 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.
Mounting position:
Indifferent (recommended position: upright; electronic part on top).
Resistance to vibrations:
30 g in ali directions
Degree of protection:
IP 65.

AlI pressure sensors with following characteristics are compatible with
the EP-transducer
Sensitivity: 0.5 V/bar up to 10 V/bar
Zero offset: -3 V/bar to 10 V/bar
