The FP0-TC4 and FP0-TC8 thermocouple units are suitable for user
friendly temperature acquisition using standard thermocouples with
high precision.
■ Up to three units can be added to each control unit, enabling
temperature control of up to 24 channels.
■ The temperature data obtained using the thermocouple is converted to
the digital value to be read into the FP0 control unit.
■ Standard types of thermocouples can be used: K, J, T and R
■ 3 temperature measurement ranges are available:
-100°C to +500°C (Thermocouple types: K and J)
-100°C to +400°C (Thermocouple type : T)
- 0°C to +1500°C (Thermocouple type : R)
■ The temperature data measured using the sensor is converted to
degrees Celsius or degrees Fahrenheit inside the Thermocouple Unit.
■ The converted data (°C or °F) is averaged, so that even unstable input
signals can be properly read.
■ Broken thermocouples can be detected.
