GENERAL

Microprocessor controller, format 48x48
(1/16 DIN) manufactured using SMT.
The instruments provides a complete
operator interface, protected by a Lexan®
membrane that ensures level IP65
faceplate protection.
They have 4 keys, 4 digits display, 2
indicating LED’s for 400 model, 3
indicating LED’s for 401 model and a
further 3 LED’s bar-graph..
The main input for the process variable is
universal and provides the possibility to
connect many types of input sensor:

• Thermocouple type J, K, R, S, T, B, E, N

• Resistance thermometer PT100 3-wires

• Thermistor PTC

• Linear inputs 0...60mV, 12...60mV,

0...20mA, 4...20mA, 0...10V, 2...10V
The type of input is selected from the
faceplate keys and no external shunts or
adapter are required.
Model 401 can have an auxiliary input for
a 50mAac current transformer to monitor
the load current.
It is also possible to set an alarm point
related to the current transformer input in
order to check eventual load malfunction.
The instruments have 2 (3 for 401 model)
relay (5A/250 V a.c., cos

ϕ

=1) or static
(10 V d.c./30mA) outputs with Heat, Cool
or Heat/Cool and/or alarm function.

All the programming procedures of the
instruments are facilitated by the grouping
of the parameters in function blocks (CFG
for the control parameters, Inp for the
inputs, Out for the outputs, etc.) and by
the possibility of selecting a simplified
menu for entering the most frequently
used parameters.
To simplify the configuration even further,
a programming kit is available for PC,
which includes a menu driven
configuration program for Windows and
the necessary cable to connect the
instrument (see technical data code
GF_eXpress).
A configurable personal software
protection code (password protection)
can be used to restrict the levels of
editing and displaying the configuration
parameters.
