The Rockwell 1756-IR6I is as an analog module for measuring temperature. It is an analog RTD and a thermocouple module which is compatible with the ControlLogix system. The 1756-IR6I module enables users to choose from the 2 data formats (the integer mode or the floating point mode). When the integer mode is enabled, the 1756-IR6I module has these features for operators to use: a notch filter, multiple input ranges, and real-time sampling. When the floating mode is enabled, it also has all the aforementioned features, in addition to the process alarms, temperature linearization, digital filtering, and rate alarms.
