7.8.11.6. Application of Logical channel in the Hardware input for TC8 modules
See also: Appendices 8.6. TC4, TC8, TC12 – THERMOCOUPLE SENSOR
MEASUREMENT MODULES and Chapter 7.8.6. Logical Channels - Math function mode.
Task:
In this example we calculate the mean value from logic channels 1÷8. In these channels
are values from thermocouple sensors that are located around the furnace.
Solution:
Before measuring temperature, user should configure the device as follows and then
connect the thermocouple sensors to the device. An example of the connection is shown in
Fig. 7.70
.

To configure logical channels for reading temperatures from 1÷8 inputs (names
Temperature 1
,
Temperature 2
, etc.) should follow the same way as in
7.8.11.2.
