GENERAL
Microprocessor based indicator in both
96x48 (1/8 DIN) formats manufactured
with SMT. The instruments have a lexan
membrane faceplate (guaranteed to IP65)
which has 3 keys, a 5 digit display and 4
indicating LED’s for the output statuses.
The input signal can be selected from a
wide range of sensors:
• Potentiometer (minimum 100Ω)
• Load cell with sensitivity autoranging
between 1,5 and 3,3mV/V.
• Strain-gauge pressure sensor
• Magnetostrictive position sensors
The selection is made using the faceplate
keys.
A digital input (24Vdc/5mA) is available
for resetting, hold, flash, peak handling or
releasing latch.
The instruments have a maximum of 4
outputs that can be mechanical relays or
logic outputs.
One output of 0/4 to 20mA (max. 500Ω) is
available for retransmitting the measured
input signal.
The retransmission output, the digital
input and the third output are options
available contemporaneously.
Finally, a triac can be fitted to drive
resistive loads up to a maximum of 1A at
240V.
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 (data sheet cod.WINSTRUM).
A configurable personal software
protection code (password protection)
can be used to restrict the levels of
editing and displaying the configuration
parameters.
