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.
Temperature input 0
Temperature input 1
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.
Temperature input 0
Temperature input 1
The temperature data will be stored in the input words allocated to the Tempera-
ture Sensor Unit in 4-digit hexadecimal.
CPM1A-TS001/TS101 and CPM2C-TS001/TS101
"m" is the last word allocated to the CPU Unit, Expansion I/O Unit, or Expansion
Unit connected immediately before the Temperature Sensor Unit.
Word
m + 1 Converted temperature data from input 0
m + 2 Converted temperature data from input 1
CPM1A-TS002/TS102
"m" is the last word allocated to the CPU Unit, Expansion I/O Unit, or Expansion
Unit connected immediately before the Temperature Sensor Unit.
Word
m + 1 Converted temperature data from input 0
m + 2 Converted temperature data from input 1
m + 3 Converted temperature data from input 2
m + 4 Converted temperature data from input 3
