FP0 Thermocouple Input Expansion Units
Enable High Precision Tempera ture Control a t Low Cost
The
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:
- 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.
