Temperature Units
You can use the following temperature units with your module:
•
Celsius
•
Kelvin
•
Fahrenheit
•
Rankine
Each channel is individually configurable for its temperature units.
To see where to set the Temperature Units, see
.
Sensor Types
This module supports multiple sensor types with the available selections dictated
by the input type configuration.
To see where to set the Sensor Type, see
.
Sensor Type Temperature Limits
Determine sensor type temperature limits by your choice of Input Type, Sensor
Type, and Temperature Units.

IMPORTANT
For the 1756-IRT8I module, the
Scaling parameters are automatically set
on the Configuration tab of the Module Properties dialog box. The Scaling
parameters
cannot be changed
in the software when configured for a Sensor
Type that returns Temperature.
The Low Signal value equals the Low Engineering value. The High Signal value
equals the High Engineering value.
