CP1E CPU Unit Hardware User’s Manual(W479)
With the Temperature Sensor Unit’s DIP switch, set the input type (temperature or analog
input), the input thermocouple type (K or J) and the temperature unit (°C or °F).
Additional Information
Fahrenheit temperature uses the following equation to convert the temperature unit from Cel-
sius, but the temperature input range is different between Fahrenheit and Celsius.
Fahrenheit temperature (°F) = Celsius temperature (°C) x 1.8 + 32

Connect Temperature Sensors.
(1) 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.
