The 1756-IT6I2 is an analog I/O module. This module is an enhanced thermocouple analog input module. That features Six (6) individually isolated thermocouple inputs and 2 CJC inputs. Thermocouple types compatible for this module are B, E, J, K, R, S, T, N, C, D, and L (TXK/XK). This module is installed to any ControlLogix chassis. It requires a Removable Terminal Block for wiring of signal wiring, specifically, only the 1756-TBNH is compatible for this module. The operating input ranges and resolutions of the 1756-IT6I2 module are -12 to 78 microvolts (1.4 microvolts per bit) and -12 to 30 mV (0.7microvolts per bit for the highest resolution range) and 16-bit resolution respectively. It has an input impedance of more than 10MOhms and a maximum overvoltage protection of 120 Volts AC/DC. Both the total backplane power and maximum power dissipation are 4.6Watts. Its thermocouple linearization is ITS-90 and offset drift is 0.5 microvolts per Degree Celsius. It also has a settling time of greater than 80 milliseconds to 5% of full scale and a channel bandwidth of 15 Hertz. Thermal dissipation is 15.7 BTU/hour. The 1756-IT6I2 has an open circuit detection time with a positive full-scale reading of 2 seconds. The integrated noise rejection in normal mode, is 60 dB at 60 Hertz while in common mode, it is a minimum of 160 dB, tested at 600 Volts AC/60 Hertz applied with 100 Ohms differential resistance. This module allows data format selection such as integer mode or a floating-point mode. Other features of the 1756-IT6I2 module include cold junction compensation, multiple input ranges, temperature units, notch filter, sensor type, real-time sampling, wire off detection, under-range/over-range detection, 10 ohms offset, a digital filter (only available in applications using floating point mode), rate alarm, and process alarms.

The 1756-IT6I2 is a ControlLogix analog input module. This module is an enhanced Thermocouple Input module that is used for Temperature measurements. It supports a wide variety of Temperature range that varies according to the thermocouple type configured. This module supports stand-alone ControlLogix implementation or Distributed I/O technology.

It is compatible for use with ControlLogix processors and communications modules. The installation limit for this module depends on the processor memory and the available slot of a specific chassis.

The 1756-ITI2 is compatible for Thermocouple sensor types such as B, E, J, K, R, S, T, N, C, D, L (TXK/XK). It features 16-Bit resolution with an analog to digital conversion method of Sigma-Delta. Configuration used for this module is RSLogix 5000 or Studio 5000 Logix designer. Selection of software depends on the firmware revision to where the module will be installed or the feature it requires. This module supports ControlFlash utility for upgrading or downgrading the firmware.

This module crates data tables that is directly accessible with the use of the programming software. The data tables are used to store the signal processed by the module, the diagnostic state and configuration parameters. Depending on the parameter, a certain bit or registers may be read, written or both.

The information within the data table is capable of being mapped to a computer-based control system for providing a readout. They may also be used in specific parts of the user program for implementation of comparison instructions to be used in dynamically configurable process alarms, arithmetic instructions and control algorithms.
