The Allen-Bradley 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. The operators of the Allen-Bradley 1756-IR6I can choose which temperature scale to use, Fahrenheit or Celsius. It comes in 4 different input ranges; 1 to 487 Ohms, 2 to 1000 Ohms, 4 to 2000 Ohms, and 8 to 4000 Ohms. The ranges stand for the minimum and maximum signals detected by the 1756-IR6I module. The 1756-IR6I comes with 6 separately isolated RTD inputs as well as 16 bits resolution and different ranges per bit: from 1 to 487 Ohms, it is 7.7 milliohms/bit, from 2 to 1000 Ohms, it is 15 milliohms/bit, from 4 to 2000 Ohms, it is 30 milliohms/bit, and then from 8 to 4020 Ohlms, it is 60 milliohms/bit.
The 1756-IR6I’s notch filter allows the user to get rid of line noise in the applications for every channel through the analog-to-digital converter (ADC). It is essential to choose a filter that best matches the expected noise frequency of the application. The digital filter fine-tunes the data noise transients on every input channel. The real-time sampling feature of the Allen-Bradley 1756-IR6I allows the module to multicast the data gathered after scanning all of its input channels. There is also an under-range/over-range detection feature that detects and informs when the temperature measuring input module starts to operate past the temperature limits set by the input range. The role of the process alarms is similar but it also signals when the module exceeds the set high/low limits in every channel. The wire-off detection feature goes off whenever a wire is disconnected from the module.

About 1756-IR6I
The Allen-Bradley 1756-IR6I module is a ControlLogix temperature-sensing analog input module. There are 6 individually isolated RTD inputs on the module. Four input ranges that are configurable are supported by the module and they are 1 to 487 Ohms, 2 to 1000 Ohms, 4 to 2000 Ohms, and 8 to 4000 Ohms. The resolution for each of the above-mentioned input ranges are 7.7 milliohms per bit, 15 milliohms per bit, 30 milliohms per bit, and 60 milliohms per bit. The 1756-IR6I module supports multiple sensors including 100, 200, 500, 1000-Ohms platinum sensors (alpha = 385), 100, 200, 500, and 1000-Ohms platinum sensors (alpha = 3916), 120-Ohms nickel (alpha = 672) sensors, and 10-Ohms copper sensors.
