ORDERING INFORMATION
MODEL NO. DESCRIPTION PART NUMBER
ITMA Intelligent Thermocouple Module ITMA3035
APPLICATION
The temperature of certain industrial plastics is critical for melt flow of
an injection molding process. Different plastic grades and the complexity
of the mold determine required temperatures for efficient material flow.
The master control room monitors the temperature of the melt flow of
each injection mold machine. They will determine whether the operator
may start the process on his machine or override the injection molding
process. The injection molding machines are located throughout the plant,
posing a thermocouple signal loss problem from long cable runs. The
ITMA DC powered unit is mounted at the machine and uses the local 24
VDC for power. The signal loss problem is solved using the 4 to 20 mA
analog output for the long cable run to the master control room.

G Rail Installation
To install the ITMA on
a “G” style DIN rail,
angle the module so that
the upper groove of the
“foot” catches under the
lip of the top rail. Push
the module toward the
rail until it snaps into
place. To remove a
module from the rail,
push up on the bottom of
the module while pulling
out away from the rail.
T Rail Installation
To install the ITMA on a
“T” style rail, angle the
module so that the top groove
of the “foot” is located over
the lip of the top rail. Push
the module toward the rail
until it snaps into place. To
remove a module from the
rail, insert a screwdriver into
the slot on the bottom of the
“foot”, and pry upwards on
the module until it releases
from the rail.
INSTALLATION
The unit is equipped with a universal mounting foot for attachment to standard DIN style mounting rails,
including G profile rail according to EN50035 - G32 , and top hat (T) profile rail according to EN50022 - 35 x 7.5
and 35 x 15. The unit should be installed in a location that does not exceed the maximum operating temperature
and provides good air circulation. Placing the unit near devices that generate excessive heat should be avoided.
