Temperature Sensor Units
Section 7-5
Note
Fahrenheit temperature uses the following equation to convert the tempera-
ture unit from Celsius, but the temperature input range is different between
Fahrenheit and Celsius.
Fahrenheit temperature (°F) = Celsius temperature (°C) x 1.8 + 32
Connecting Temperature
Sensors
Thermocouples
Either K or J thermocouples can be connected, but all four thermocouples
must be the same type and the same input range. Only last two channels can
be used as analog inputs.
Note
When connecting a thermocouple input, observe the following precautions:
• Do not remove the cold junction compensator attached at the time of
delivery. If the cold junction compensator is removed, the Unit will not be
able to measure temperatures correctly.
