Electrical data
Supply voltage 20 mA mode: 12... 30 VDC, smoothed, not stabilized
2 V mode: 5...30 VDC, smoothed, not stabilized
To drive a current of 20 mA through a signal line with a series resistance of 600
Ω
a power supply voltage of 18 V minimum is needed.
Current consumption 12...30 V; 20 mA mode; without load: < 10 mA quiescent current; typically approx. 8 mA
12...30 V; 20 mA mode; 20 mA output: < 30 mA; typically approx. 28 mA
12...30 V; 2 V mode, without load: < 3 mA; typically approx. 2 mA
5...30 V; 2 V mode; 1000
Ω
load resistance: < 5 mA; typically approx. 4 mA
(5...30 V; 2 V mode; 470
Ω
load resistance: < 7 mA; typically approx. 6 mA;
not specified)
Power consumption 30 V x 30 mA = 900 mW max.; 5 V x 2 mA = 10 mW min.
Analog outputs 0...20 mA; 4...20 mA; 0...2 V selectable/ adjustable
Current output: 20 mA max.; 30 V max.; series impedance 600
Ω max.
Voltage output: 2 V max. at 1000
Ω
min., parallel 100 nF max.
Inrush current depending on source impedance, equivalent capacity at power supply
input: approx. 47 µF.
Time from power on to first valid value: approx. 3 seconds.
Every following measurements are taken in intervals of approx. 3 seconds. Due to
sealing of the enclosure measured values lag behind the true pressure by 30 s...60 s.
