The CSi32 Series is the newest
in Omega’s line of benchtop
controllers. They feature a 1⁄32 DIN
size (96 x 48 mm) digital panel
controller in a rugged benchtop
metal enclosure. The controller
used is Omega’s award winning and
patented iSeries with color-changing
display. 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. Other options include, serial
communications. These
controllers can be purchased
factory configured for one of
10 common types of
thermocouples, multiple
RTD types, or process (DC)
voltage and current. They
are ideal for laboratory use
and applications requiring

portable temperature and process
control. Pre-wired input and output
receptacles in the rear of the case
enable quick and easy connections
to power, input, power output and
digital communications.
The iSeries are full PID controllers
with Autotune and can also be
programmed for On/Off control via
the front panel or through
the use of a PC and the
free configuration software.
The iSeries configuration
software is designed to
interface with the any of
the iSeries controllers and
the CSi32 Series benchtop
controllers with optional
communication hardware.

9-segment LED
The iSeries displays feature unique
9-segment LED characters, which
greatly improve 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 easier.
