• Thermocouple input unit for FP3/FP10S
This unit converts temperature data from a thermocouple sensor into digital values for processing by an FP3 or
FP10S CPU.
• Supports K and J type thermocouples
Temperature sensors which may be used are the K and J types.
• Automatic zero point correction
With the zero point correction sensor, the measured value of thermocouple sensor is automatically converted to
Celsius. Therefore, no complex calculation is required for handling data in an FP3 or FP10S.
• Four selections for temperature measurement range
The following selections are available for the measurement range:
- 0 °C to 200 °C/32 °F to 392 °F (with a K or J type)
- 0 °C to 400 °C/32 °F to 752 °F (with a K or J type)
- 0 °C to 600 °C/32 °F to 1,112 °F (with a K or J type)
- 0 °C to 1000 °C/32 °F to 1,832 °F (with a K type)
• Two data styles available
In addition to converting the temperature data in normalized 0 to 4000 form, the unit can also express the data in
digital Celsius data. (The Celsius data is expressed up to the 0.1 degree accuracy by multiplying 10 and the Celsius
value together.)
• Offset settings possible for Celsius data
An offset value can be set to correct the Celsius data when the data given differs from those of other measuring
instruments due to measurement error.
• Averaging function available for regular and Celsius data
The unit also has function for averaging normalized and Celsius data. This enables an FP3 or FP10S to handle
unstable data.
• Easy-to-use self-diagnostic functions
The unit can detect the disconnection or the broke of thermocouple sensor and temperature range abnormality.
• Shared memory based communication between an FP3/FP10S CPU and a thermocouple input unit
Data exchanges between the FP3/FP10S CPU and a thermocouple input unit can be performed using the shared
memory of the unit. By executing the F150 (READ)/P150 (PREAD) and F151 (WRT)/P151 (PWRT), CPU can
read various digital data, such as normalized, Celsius and their averaging data, its self-diagnostic condition etc. and
can write offset enable flags and offset values.
