FP0 Thermocouple Input Expansion Units

Enable High Precision Tempera ture Control a t Low Cost

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.
