PROFILE
The series 450 temperature controller,
measuring 48x48mm (1/16 DIN), offers
simplicity of use and high quality of control.
The input from temperature sensors is
“universal” and configurable with type J,
K, R, S, T, B, E, N thermocouples and
with 3-wire Rt100 resistance thermometers.
The user interface has a complete double
display with green LEDs, 4 keys, and two
red LEDs to signal active outputs.
The Lexan® membrane on the front
panel guarantees an IP65 protection level
for these products.
The controller outputs, freely configurable
as control output and alarm output, are
available in a 5A/250VAC relay version
or in a logic signal version to drive solid
state relays.
The input signal read speed (120msec)
and the tested PID control algorithm with
selftuning and autotuning parameter
functions guarantee accurate and stable
control even for rapid and discontinuous
heating systems.
Series 450 models are factory-configured
to satisfy most industrial heating applications (input for probe J, hot PID setting,
10 second cycle time) and can always be
modified from keyboard and from PC with
a few parameters grouped on intuitive
menus.
A programming kit for PC is available,
consisting of a cable and a user-friendly
program for Windows with Wizard pages,
oscilloscope for process analysis, saving
of parameter recipes, and ability to reset
factory parameters. A settable software
protection code (password-protected) lets
you limit access to internal parameters to
various levels, up to total protection.
