The OMEGA® CNi8 is a 18 DIN size
[96 x 48 mm (3.7 x 1.9")] digital
panel meter featuring the big
iSeries color-changing display. The
digits are twice the size of typical
18 DIN panel
meters. The iSeries
meters feature the only LED displays
that can be programmed to change
color between GREEN, AMBER,
and RED at any setpoint or alarm
point. The “CNi8” model is available
as an extremely accurate
programmable digital panel meter
with no outputs or with dual outputs
for controlling or alarming functions.
Other options include isolated
programmable analog output, serial
communications, MODBUS and
Ethernet. The user can easily program
the CNi8 for any control or alarming
requirement from simple on/off to
full autotune PID with a choice of
form C SPDT relays, solid state
relays, DC pulse, and analog
(voltage and current) outputs.
Fully isolated analog output for
retransmission of the process value
is available in addition to the control
and alarm relays (specify model
CNi8A33).
The CNi8 covers a broad selection
of transducer and transmitter inputs
with 2 input models:
The universal temperature and
process instrument (model “i”)
handles 10 common types of
thermocouples, multiple RTD’s, 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 instrument
(model “iS”) measures 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 “iS”
model supports 4- and 6-wire bridge
configurations, ratiometric and nonratiometric
measurements. The “iS”
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.
