GENERAL

Microprocessor based indicator in
96x48 (1/8 DIN) format manufactured
with SMT.
The instruments have a lexan mem­brane faceplate (guaranteed to IP65)
which has 3 keys, a 4 digit display and
3 indicating LED’s for the output statu­ses.
The input signal can be selected from a
wide range of sensors:

• voltage free mechanical contact

• Inductive or capacitive proximity
switch, encoder or Namur 2 / 3 wires

• 30 to 500Vac, 1mA alternating voltage
command

The selection is made using the face­plate keys.
A digital input (24Vdc/4mA) is available
for resetting, hold, flash, peak handling
or releasing latch.
The instruments can have a maximum
of 3 outputs that can be mechani­cal relays (5A/250V) or logic outputs
(0 to 11Vdc).

One output of 4 to 20mA (max. 150Ω)

is available for retransmitting the mea­sured input signal.
Finally, a triac can be fitted (as an alter­native to the other two relay

outputs) to drive resistive loads up to a
maximum of 2,5A at 220V.
The programming of the instrument is
made easy by grouping the parameters
in function blocks (CFG for the alarm
hysteresis, Inp for the inputs, Out for
the outputs...) 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 technical data cod. 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

± 1 digit with f.s. fixed
Main input from:

• voltage free mechanical contact
configurable in opening/closing,
100Hz filter settable from
configuration

• voltage logic command with 0,5 to
30Vdc, 6mA max. range, for
inductive or capacitive proximity
switch, encoder or NAMUR 2 or 3
wires

• 30 to 500Vac, 1mA max. alternating
command
10KHz max. input signal frequency with
50% duty cycle (prescaler set to 1, 2, 4,
10, 20, 40, 100).
Frequency meter with automatic deci­mal point autoranging for 9,999; 99,99;
999,9; 9999Hz frequency values with
0,1% full scale accuracy.
Freely settable decimal point position,
with fixed full scale.
Frequency evaluation modality with set­table sampling time, useful for defining
a max. interceptions delay time.
Transformation in engineering units is
possible through the insert of a multi­plier, a divisor and a scale offset (i.e.

for visualisation, RPM interception).

Digital input

to peak).
