CSi8DH shown
smaller than
actual size.

The OMEGA® CSi8D is a 1⁄8 DIN size
(96 x 48 mm) digital panel controller
in a rugged benchtop metal enclosure
featuring the big iSeries
color-changing display. The digits
are twice the size of those 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 at any setpoint or

alarm point. Other options include,
serial communications, MODBUS®,
and Ethernet.

The universal temperature and
process instrument (model “i”)
handles 10 common types of
thermocouples, multiple RTDs,
and several process (DC) voltage
and current ranges. Units can be
reconfigured in the field.

PATENTED

At Any

Setpoint

Totally Programmable
Color Displays

The OMEGA® i/8, i/16, and i/32 are
the first complete series of 1⁄8, 1⁄16, and

1

⁄32 DIN process control instruments
with totally programmable color
displays.The
display can be
programmed to
change color at
any setpoint or
alarm point.
