*Move on up to our newest line of PID Controller, the CNPT Platinum Series controllers with Modbus connectivity, expanded ramp and soak programs, universal inputs, and simple PC programming.*
The OMEGA™ iSeries is a family of
microprocessor-based instruments
offered in three true DIN sizes with
NEMA 4 (IP65) rated front bezels.
All of the instruments share the same
set-up and configuration menu and
method of operation, a tremendous
time saver for integration of a large
system. The iSeries family includes
extremely accurate digital panel
meters "DPi" and single loop PID
controllers "CNi" that are simple to
configure and use, while providing
tremendous versatility and a wealth
of powerful features.
The CNi Series covers a broad
selection of transducer and
transmitter inputs with 2 input
models.
The universal temperature and
process instrument (CNi models)
handles 10 common types of
thermocouples, 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
(CNiS models) measure inputs from
load cells, pressure transducers,
and most any strain gage sensor as
well as process voltage and current
ranges. The CNiS 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
CNiS model supports 4- and 6-wire
bridge communications, ratiometric
measurements. The CNiS 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.
Programmable
Color Display
The iSeries are 1/8, 1/16 and 1/32 DIN
controllers featuring the big
iSeries color-changing display. The
digits are twice the size of typical
1/8 DIN panel meters. The iSeries
meters feature the only LED displays
that can be programmed to change
color between GREEN, AMBER, and RED.
Embedded Internet and Serial
Communications
Featuring optional
"embedded Internet" (specify "-EIT"
option) the iSeries are the first
instruments of their kind that connect
directly to an Ethernet network and
transmit data in standard TCP/
IP packets, or even serve Web
pages over a LAN or the Internet.
The iSeries are also available with
serial communications. With the
"-C24" option, the user can select
from the pushbutton menu between
RS232, RS422, and RS485, with
straightforward ASCII commands. If Modbus is required, we recommend our latest Platinum controllers - CNPT Series.
