Temperature Sensor Units Section 7-5
Main Specifications
Note Accuracy for a K-type sensor at −100°C or less is ±4°C ±1 digit max.
Using Temperature Sensor Units
Connecting Temperature
Sensor Units
A maximum of three CP1W-TS002 and CP1W-TS102 Temperature Sensor
Units can be connected, because each unit is allocated four words.
