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.
