• Do not touch the cold junction compensator. Doing so may result in incor-
rect temperature measurement.
Platinum Resistance Thermometers
CP1W-TS101
One or two Pt or JPt 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.
CP1W-TS102
Up to four Pt100 or JPt100 platinum resistance thermometers can be con-
nected, but all four of the thermometers must be of the same type and the
same input range must be used for each.
Note Do not connect anything to terminals not used for inputs.

Word Allocations
Temperature Sensor Units are allocated words in the same way as other CP-
series Expansion Units or Expansion I/O Units, in order of connection. A Tem-
perature Sensor Unit is allocated the next input words following the input
words of the CPU Unit or previous Expansion Unit or Expansion I/O Unit. Four
input words are allocated to the 2-input CP1W-TS001 or CP1W-TS101 and
four input words are allocated to the 4-input CP1W-TS002 or CP1W-TS102.
No output words are allocated.
