Thermocouple
unit
-
Features
1. Highly accurate temperature control
Overall accuracy of ±0.8°C (K, J, T range)
enables highly accurate temperature control.
2. Temperature control up to 24 channels
Four and eight channel units are available to make
temperature control up to 24 channels possible.
3. Easy multi-stage temperature control
By combining with PID instruction, temperature
profiling control is realized.
4. Support K, J, T and R thermocouples to
cover all major applications
K and J (-100 to 500°C)
T (-100 to 400°C)
R (0 to 1500°C)

Notes
1) The measurement range available for degree
Celsius is not available for degree Fahrenheit, of which the
upper-limit measurement is set lower than degree Celsius, since
the digital value (temperature value displayed) for degree
Fahrenheit is bigger than that for degree Celsius.
2) When the thermocouple is broken, the digital
value will become K8000 or K16000 within 70 seconds since broken.
Practice in the ladder program a process for avoiding a risk,
would be resulting from a broken thermocouple, and exchange the
thermocouple.
3) Until the conversion data will be ready after
the initial startup was made, the digital value shows K8001 or
K16001. Those are not a temperature data. Create a ladder program,
so that they are not acquired as a temperature data.
4) The settings of the input channel selection
switch.
5) Conversion values for 6-time measurements (6
from the latest 8 measurements, excluding the max. and min.) are
averaged, so that it takes time for the digital value to be
displayed due to the rapid temperature change.
6) The control unit reads the data for 2 channels
per 1 scan by the control unit. Read data by utilizing the sample
program given in the product specifications and manual.
