GENERAL

Microprocessor based indicator in both
96x48 (1/8 DIN) formats manufactured
with SMT.
The instrument have a lexan
membrane faceplate (guaranteed to
IP65) which has 3 keys, a 3 / 4 digit
display .
The input signal can be selected from a
wide range of sensors:

• Thermocouples of type J, K, R, S, T,
B, E, N, L GOST, U, G, D, C

• Resistance thermometers Pt100,
JPt100; 2 / 3 wire

• PTC and NTC themistors

• Linear inputs 0 to 60/12 to 60mV,
0 to 20/4 to 20mA,
0 to 10/2 to 10/0 to 5/1 to 5/0 to 1/0,
2 to1V

The selection is made using the
faceplate keys and correct input
contact.
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 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
I

NPUTS

Accuracy 0,2% f.s. ±1digit.
Sampling time 120msec for temperatu­re sensors, configurable for linear
inputs down to a minimum of 15msec
with reduction of the resolution to 4000
steps.
Configurable decimal point position for
linear inputs, for TC, RTD, PTC and
NTC inputs, only one decimal digit is
allowed in the maximum display range
of -199.9 to 999.9 (4 digit display) and

-99.9 to 99.9 (3 digit display with sign)
with indication of open circuit thermo­couple or RTD, PTC or NTC in open or
short circuit, indication of over- and
under-range for linear inputs.
