IDR & ISDR models have been discontinued. As a possible substitute, please check out the CS Series or DRST Series for details.
The OMEGA™ iDR DIN rail iSeries
is a family of microprocessor-based
instruments offered in 3 sizes. The
instruments have a similar setup and
configuration menu and method of
operation, which is a tremendous time
saver for integration of a large system.
The iDR instruments offer a broad
selection of signal inputs. The choices
are easily selected from the remote
programmer menu with 4 front-panel
pushbuttons, or by serial or Ethernet
communications.
The iDR handles 10 common types
of thermocouple, multiple RTDs
and several process (DC) voltage
and current ranges. This model also
features built-in excitation, 24 Vdc @
25 mA. With its wide choice of signal
inputs, this model is an excellent
choice for measuring or controlling
temperature with a thermocouple,
RTD, or 4 to 20 mA transmitter.
The strain and process instruments
(iSDR models) measure inputs from
load cells, pressure transducers,
and most any strain gage sensor as
well as process voltage and current
ranges. The iS has built-in
5 or 10 Vdc excitation for bridge
transducers, 5 Vdc @ 40 mA or
10 Vdc @ 60 mA (any excitation
voltage between 5 and 24 Vdc is
available by special order). This
model supports 4- and 6-wire
bridge communications, ratiometric
measurements.
The iSDR features fast and easy “in
process” calibration/ scaling of the
signal inputs to any engineering units.
This model also features 10-point
linearization which allows the user
to linearize the signal input from
extremely nonlinear transducers of
all kinds.
The iDR offers either simple
manual on/off operation or full
autotune PID control (selectable
preset tune, adaptive tune, PID, PI,
PD control modes). The dual control
outputs can be configured for a
variety of independent control and
alarm applications, such as
heat/heat, heat/cool, heat/alarm,
cool/cool, cool/alarm, or
alarm/alarm. The ramp-to-setpoint
feature allows the user to define the
rate of rise to setpoint, minimizing
thermal shock to the load is during
start-up. For those who only need
simplified menus and no PID control, a
limit alarm (-AL) option is available.
Users have a choice of 2 control or
alarm outputs in almost any
combination: solid state relays
(SSRs) form “C” SPDT relays and
pulsed 10 Vdc output for use with
an external SSR.
The optional analog output can be
programmed within a range of
0 to 10 Vdc or 0 to 20 mA. It is
selectable as either a control output
or as a calibrated retransmission of
the process value—a unique feature
among controllers.
The remote programmer/display
can be programmed to change color
at any setpoint or alarm point. For
example, the instrument can be
programmed to display the process
value in GREEN during warm-up,
in AMBER to signal the normal
operating range, and in RED to
signal an alarm condition.
Embedded Web Server option allows
you to connect directly to an Ethernet
network and transmit data in standard
TCP/IP packets, or serve Web
pages over a LAN or the Internet.
With the serial communication
option, the user can select from
the pushbutton menu between
RS232, RS422, and RS485, with
straightforward ASCII commands
or MODBUS.
