Temperature Sensor Units
By mounting a Temperature Sensor Unit (CPM1A-TS001/TS002/TS101/TS102) to the PC, input can be obtained from a thermocou-
ple or platinum resistance thermometer,and temperature measurements can be converted to binary data (4-digit hexadecimal) and
stored in the input area of the CPU Unit. For details on the maximum number of connectable Units, refer to 7.
