Chapter 2 ControlLogix Isolated Analog I/O Module Features
Calibration The ControlLogix isolated analog modules are calibrated via the
following methods:
• Factory calibration when the modules are built.
• User-executed calibration as described in Chapter 8 , Calibrate the
ControlLogix Isolated Analog I/O Modules on page 137 .
User-executed calibration is optional.
• 1756-IRT8I module only - Channels configured for Thermocouple
inputs perform a lead resistance self-calibration when the module power
is cycled.
Calibrated Accuracy The Calibrated Accuracy specification represents the module’s accuracy when
its ambient temperature is the same as the temperature at which the module
was calibrated.
The following specifications are related to Calibrated Accuracy:
• Calibrated Accuracy at 25 °C (77 °F)
• Module Error over Full Temperature Range
Calibrated Accuracy at 25 °C (77 °F)
This specification matches the temperature at which the module was calibrated
in the factory during manufacturing.
The module’s accuracy when operating in 25 °C (77 °F) conditions = 0.05%.
