Temperature Sensor Units
Section 7-5
Platinum Resistance Thermometers
CPM1A-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.
CPM1A-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.

Program Word Allocations
Temperature Sensor Units are allocated words in the same way as CPM1A
Expansion Units or Expansion I/O Units, in order of connection. A Tempera-
ture 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 is to the 2-input CPM1A-TS001 or CPM1A-TS101 and
four input words are allocated to the 4-input CPM1A-TS002 or CPM1A-
TS102. No output words are allocated.
