PROFILE

Microprocessor controllers, 48x96
(1/8DIN) format for 1200 and 96x96
(1/4DIN) format for 1300, built with SMT
technology. Complete operator interface,
protected by Lexan membrane to
guarantee an IP65 faceplate protection
level. Composed of 4 keys, double 4-digit
green LED display, 4 red signal LEDs for
the 4 relay/logic outputs and 3 additional
LEDs with programmable function to
signal the instrument’s various function
states.
The main input for the variable to be
controlled is universal, and allows
connection of a wide variety of signals:
thermocouples, resistance thermometers,
thermistors, normalized linear inputs, all
with possibility of custom linearization set
from the faceplate.
Input type is selected entirely from the
faceplate and requires no external
adapter shunts/dividers.
A second auxiliary analog input from
current transformer is available. You can
select one of the two presettable
setpoints, select Manual-Automatic mode,
reset the alarm memory, or enable the
hold function by means of the digital
input.
The instrument provides up to 4 outputs:
relay (5A, 250VAC/30VDC cos

ϕ

= 1) or

logic (24V ± 10% (10Vmin a 20mA).

An analog output in voltage or in current
is also available.
The functions of each output are freely
configurable from the faceplate.
In addition to the control and alarm
outputs, you can also have outputs that
repeat the state of the digital or
retransmission input by process variable,
setpoint, deviation, alarm trip points and
values acquired via serial line. An
additional output (24VDC, 30mA max.) is
available to power outside transmitters.
The serial communication option can be
in Current Loop or RS485, with MODBUS
RTU protocol and maximum speed of
19200 baud (485).
The instrument’s entire programming
procedure is made easier by grouping the
parameters in function blocks (CFG for
control parameters, Inp for inputs, Out for
outputs, etc.).
The instrument can also select the
parameters to be displayed based on its
hardware configuration, which
automatically hides irrelevant parameters.
The instrument is supplied with an
“EASY” configuration calling for just a few
parameters (only those pertaining to the
model ordered and essential to the
controller’s operation).
In this way, you just have to set the
setpoint and the alarm, then launch self­tuning with the specific button.

For even simpler configuration, you can
use a PC programming kit consisting of a
cable and a guided program for Windows
environment (see Technical Data code
WINSTRUM).
