3-2-2 CPM2C Temperature Sensor Units
With the CPM2C (including the CPM2C-S), up to four CPM2C-TS001/TS101
Temperature Sensor Units can be connected (up to three Units for the
CPM2C-S). Each Temperature Sensor Unit provides 2 input points meaning that
a total of 8 input points can be used. The inputs can be from thermocouples or
platinum resistance thermometers.
