GENERAL
Microprocessor based indicator in both
48x48 (1/16 DIN) and 96x48 (1/8 DIN)
formats manufactured with SMT.
The instruments have a lexan membrane faceplate (guaranteed to IP65)
which has 3 keys, a 3-digit display for
the 48x48 format or a 3 / 4 digit display
for the 96x48 format.
The input signal section provides for
the visualisation of the sinusoidal effective value corresponding to following
signals:
• AC voltage:
0 to 2, 0 to 20, 0 to 200 and
0 to 500Vac
• AC current:
0 to 20, 0 to 50, 0 to 200mAac
0 to 1, 0 to 5Aac
The selection is made using the faceplate keys and correct input terminals.
No external shunt or adapter is required.
The programming of the instrument is
made easy by grouping the parameters
in function blocks and by a simplified
data entry menu.
The configuration can be simplified
even further using the PC programming
kit made up of a connection cable and a
menu guide program that runs under
Windows (see data sheet code WINSTRUM).
A configurable personal software protection code (password protection) can
be used to restrict the levels of editing
and displaying the configuration
parameters.
TECHNICAL DATA
Inputs
Accuracy:
0,2% f.s. ±1 digit for 2Vac, 20Vac,
20mAac, 50mAac, 1Aac inputs
0,5% f.s. ±1 digit for 200Vac, 500Vac,
200mAac, 5Aac inputs
The measurement of the effective value
considers the sinusoidal signal.
Sampling time 120msec, resolution
8000 steps.
Configurable decimal point position,
scale -1999 to 9999 (4 digit display) or
-999 to 999 (3 digit display with sign,
only for the 96 format) with over- and
under-range indication.
Voltage input for 2Vac, 20Vac, 200Vac,
500Vac with Ri > 1MΩ.
Current input for 20mAac, 50mAac,
200mAac with Ri = 1,6Ω.
Current input for 1Aac, 5Aac with
Ri = 16mΩ.
