The OMEGA® MDSi8 is a 1⁄8 DIN
size (96 x 48 mm) digital panel
meter in a rugged benchtop metal
enclosure 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 at any setpoint or alarm
point. Other options include isolated
programmable analog output, serial
communications, MODBUS and
Ethernet.
The universal temperature and
process instrument (model “i”)
handles 10 common types of
thermocouples, multiple RTD’s, and
several rocess (DC) voltage and
current ranges.

Totally Programmable
Color Displays
The OMEGA® i/8, i/16, and i/32 are
the first complete series of
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.
