MDS8PT shown smaller than actual size.
The OMEGA® MDS8PT is a
1⁄8 DIN size (96 x 48 mm) digital
panel meter in a benchtop plastic
enclosure featuring the Pt Series
color-changing display.
The Pt Series meters feature
4 or 6 digit LED displays that can
be programmed to change color
between GREEN, AMBER, and
RED at any set-point or alarm
point. Other options include
isolated programmable analog
output, serial communications,
Modbus® and Ethernet.
The universal temperature and
process instrument handles 10
common types of thermocouples,
thermistors, multiple RTD’s, and
several process (DC) voltage and
current ranges.

General
Power: 90 to 240 Vac, 50 to 60 Hz
Note: Power cords for 120 Vac operation are
available. See “Accessories.”
The Pt Series 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 Pt Series,
which makes
operating and
programming
simpler and easier.
