Single-loop microprocessor
controller, 96 x 96 (1/4 DIN) format, appropriate
for processes with high variation speed.
Thanks to its extended functions and configurable hardware
and software, it provides high applicative flexibility
in systems that control and monitor pressure, force,
temperature, and differential pressure, and can acquire
up to 4 variables.
It has two main analog inputs, configurable for strain
gauge / potentiometer / linear signal / TC / RTD (one
of which is optional) and two auxiliary analog inputs
for linear signals (for example, remote set point functions
and line speed reference input).
Two isolated analog outputs (one of which is optional)
are available for control.
The operator interface, with IP54 protection level
(IP65 with protective cover) is equipped with a 6-key
soft-touch keyboard, triple 5-digit display (one of
which is 2-color), and two bar graphs with configurable
function.
Controls and commands can be sent from the front panel
or via 4 digital inputs that can be assigned functions
such as reset, calibration, man/auto, loc/rem, hold,
raise/lower (motopotentiometer function), parameter
set selection, set point selection.
The instrument has 4 configurable relay outputs as
standard.
More extended configurations are available with the
following options:
- isolated analog output for retransmission of process,
peak, remote set, deviation, alarm set point, differential
values
- expansion with 4 I/O
- communication interface.
CONTROLLER
Self-adapting PI control or double-action
PID (heating/cooling), ratio controller, differential
pressure controller, selftuning, continuous or one-shot
autotuning, Auto/man, Loc/rem, set point gradient,
power gradient, dynamic power limits.
8 sets of selectable PID parameters based on set point
level.
ALARMS
3 completely configurable alarm set points.
Selectable “failsafe” function.
MATH FUNCTIONS
The 2500 controller lets you define two distinct
math relations between two analog inputs.
The results can be freely used as set points, alarm
set points, control output, etc...
DIGITAL COMMUNICATION
The instrument offers an optional RS485 2/4
wire / RS232 serial interface with MODBUS RTU protocol
for access to instrument parameters.
CONFIGURATION
The programming procedure is facilitated by
the menu structure, with various configuration levels
for quick and simple data search.
