CPM2C Temperature Sensor Units
CPM2C-TS001 (Thermocouples)
Either K or J thermocouples can be connected, but both of the thermocouples
must be of the same type and the same input range must be used for each.

Note
When using a Temperature Sensor Unit with a thermocouple input, observe the
following precautions:
•
Do not touch the cold junction compensator. Doing so may result in incor-
rect temperature measurement.
CPM2C-TS101 (Platinum Resistance Thermometers)
Either Pt100 or JPt100 platinum resistance thermometers can be connected,
but both of the thermometers must be of the same type and the same input range
must be used for each.

The temperature data will be stored in the input words allocated to the Tempera-
ture Sensor Unit in 4-digit hexadecimal.

“m” is the last word allocated to the CPU Unit, Expansion I/O Unit, or Expansion
Unit connected immediately before the Temperature Sensor Unit.
