Cost-effective controllers family
The new Gefran family of PID controllers,
including the models, has numerous
integrated functions which reduce the
number of devices installed on a machine
and simplify configuration.
Thanks to accurate control, numerous options and exclusive
functions, the PID controllers by Gefran (which is
available with three models, 850/1650/1850) the system
regulating and controlling a production process can be simplified,
installing one single device instead of several (double
regulator, PLC and HMI, timer).
This means the perfect word to describe the new range is “costeffective”,
as it delivers significantly lower purchase, installation
and operating costs with high precision, stable measurement
and PID regulation combined with logical and mathematical
functions.
These features make the Performance series the ideal solution
for regulated processes such as heat treatment of metals,
laboratory equipment, and pharmaceutical and medical
sterilisation processes requiring particularly precise, accurate
measurement.
Il modello 1650: la serie condivide molte
caratteristiche della famiglia precedente.
The 1650 series shares many of the
exclusive features of the previous family.
Tutte queste caratteristiche rendono la serie Performance
ideale per processi regolati come il trattamento termico
di metalli, apparecchiature di laboratorio, processi di
sterilizzazione nel settore farmaceutico e medicale, che
richiedono alta precisione di misura e accuratezza.
Alle caratteristiche esclusive
si aggiungono funzioni integrate
I nuovi regolatori lanciati da Gefran sono l’evoluzione
della famiglia 650/1250/1350, premiata lo scorso anno
da Frost & Sullivan come miglior regolatore PID dell’anno
per la sua categoria, e continuano il processo di ampliamento
della gamma. La serie 850/ 1650/ 1850, disponibile
in tre formati (1/16, 1/8 e ¼ DIN), condivide molte
Numerous integrated functions
are addeed to the exclusive features
The new controllers continue the process of expanding the
range and represent the evolution of the 650/1250/1350 family,
which Frost & Sullivan named PID regulator of the year in its
category last year. The 850/ 1650/ 1850 series, available in
three sizes (1/16, 1/8 and ¼ DIN), shares many of the exclusive
features of the previous family, and offers even more.
A series of features remain unaltered, such as the customisable
display, bright lighting and high resolution for easy reading by
the operator, easy configuration with a software tool, multilingual
messages, functions for planning preventive maintenance and
constant monitoring of energy consumption.
In addition, the new series offers numerous integrated functions
permitting reduction of the number of devices installed on a
machine, simplifying configuration: two independent control
loops to replace two controllers with one and save on wiring
and structural work; 32 integrated timers, a single regulator in
place of a timer + regulator; 32 logical blocks, 8 mathematical
blocks and additional I/Os: there is no need of a PLC to perform
simple control functions such as checking authorisations,
machine start/stop commands and alarms, counting pieces
produced, making comparisons, etc. And there is no need
for an experienced programmer or for complex programming
software, the free configuration tool is sufficient.
