The iSeries displays feature unique 9‑segment LED characters, which greatly
improves alphanumeric representations. The 7‑segment LED characters found
on most instruments are adequate for presenting numbers, but not letters.
Words are easier to read with the unique
9‑segment LED characters on the iSeries,
which makes operating and programming
simpler and easier.

The OMEGATM CNi32 is the iSeries
controller in the extremely compact
and increasingly popular 1⁄32 DIN size
(22.5 x 45 mm cutout). The CNi32 is
the most sophisticated and accurate
instrument available in the small
1⁄32 DIN package, yet is still easy
to configure.
The CNi32 handles more
thermocouple, RTD, process
voltage and current inputs than
any other 1⁄32 DIN controller.
The CNi32 is the first 1⁄32 DIN
controller with built‑in excitation
for transmitters or other devices,
24 Vdc @ 25 mA.
The CNiS32 has built‑in excitation
for bridge transducers, 5 Vdc @
40 mA or 10 Vdc @ 60 mA. When
communications options are
installed, external excitation may
be used and ratiometric operation
maintained by connecting the
external excitation to the sense
leads. Both 4‑ or 6‑wire bridge
configurations are supported for
internal or external excitation.
Non‑ratiometric operation is supported
for voltage and current transducers
and is also valuable in measuring
offset and millivolt output of bridge
devices during manufacturing and
calibration. This model also features
10‑point linearization which allows
the user to linearize the signal
input from extremely nonlinear
transducers of all kinds.
The CNi32 introduces a number of
unique features not yet found on any
other 1⁄32 DIN instrument. The CNi32
is the first 1⁄32 DIN controller with a
totally programmable display that
can change color between GREEN,
AMBER, and RED at any setpoint
or alarm point.The unique 9‑segment
LED characters greatly improves
alphanumeric representations.
The CNi32 is the first 1⁄32 DIN
controller offering 2 SPDT Form C
relays, instead of the single throw
relays on typical 1⁄32 DIN controllers.
The CNi32 is the first to offer
both RS232 and RS422/485 serial
communications in 1 instrument
(C24 option). The ASCII protocol is
selectable from the menu.
