GENERAL
Microprocessor setpoint programmer and
controller in 48x96 / 96x96mm format
(1/8 DIN -1/4 DIN).
Manufactured using SMT, the 3500 provides a complete operator interface with
IP54 level of protection (IP65 with faceplate cover).
The faceplate has a membrane keypad
with 6 keys, a backlit LCD display that is
available also with large dimensions
(model 4500) that displays the process
variable, setpoint, bargraphs of the percentage output power and the deviation
and indication of the alarm and controller
states.
The main input for the control variable is
universal and gives the possibility to connect a wide range of sensors such as
thermocouples, resistance thermometers
or mV signals even with custom linearisation.
A second optional auxiliary analogue
input is available for remote setpoint
linear signal, potentiometer valve position
feedback or input from a current transformer.
With a digital input it is possible to select
between two preset setpoints or switch
between local and remote setpoint.
With three isolated digital inputs, it is possible to supply a start, stop and reset
signal.
The model 4500 offers the possibility of a
further eight isolated programmable digital inputs for enabling and stepping the
programme. The instrument has up to
four outputs, each one factory configured,
according to the order code, as relay, isolated logic, isolated analogue or interface
for MD81 expansion unit output.
The output functions are configurable
from the faceplate.
Apart from the control outputs, that can
be heat-cool with independent PID, and
the alarm outputs, outputs can be dedicated to the open/close control of a motorised valve (with or without position feedback potentiometer), retransmission
signal of the measured variable, the setpoint, the deviation or the control of the
MD8 expansion unit for an extra 8 alarm
or programmable event outputs.
The model 4500 gives the possibility of
an extra eight isolated digital outputs
freely programmable for each step of the
programme..
The 3500/4500 series programmer-controllers can use up to 100 steps (100
ramps and 100 holds), grouped in 50 different programmes.
The programmer can have a cyclic function, a time base configurable from
seconds to days, software alarms for the
control of the response of the controlled
system and four different modes of restart
after a power out.
The serial communication option can be
for Current Loop, RS232 or RS422/485,
with selectable CENCAL or MODBUS
protocol, and it is possible to read and
write any of the instrument’s parameters.
The programming procedure is simplified
by the menu guide structure with different
configuration levels for a rapid and easy
access to the data.
