Information About 1756-IT6I2 

The Allen Bradley 1756-IT6I2 ControlLogix Enhanced Isolated Thermocouple/Mv Input 6P is a temperature-measuring thermocouple/millivolt analog input module designed for ControlLogix systems. It features six individually isolated thermocouple inputs and two cold-junction sensors (CJS). The input range includes -12-78mV and -12-30mV, with a resolution of 16 bits. The module linearizes millivolt inputs into temperature values, which can be displayed in Celsius or Fahrenheit.

This module is equipped with 20-pin connectors for each thermocouple input. It supports a range of thermocouple types including B, C, D, E, J, K, L, N, R, S, and T. The input resolution of the module is 1.4 µV/bit for the -12-78mV range and 0.7 µV/bit for the -12-30mV range.

The Allen Bradley 1756-IT6I2 operates with a backplane current of 120 milliamps at 24 volts and 200 milliamps at 5 volts. It has a module scan time of 25 milliseconds for floating-point (millivolt) inputs, 50 milliseconds for floating-point (temperature) inputs, and 10 milliseconds for integer (millivolt) inputs.

The module supports data format in integer mode with left-justified, 2's complement IEEE 32-bit floating point. It is designed for use in ControlLogix systems and is part of the CompactLogix series.

In terms of power dissipation, the maximum power dissipation of the module is 4.6 Watts. It is equipped with removable terminal blocks, including 1756-TBNH and 1756-TBSH. The module's backplane current at 24 volts is 150 milliamps, and it consumes 2 milliamperes of current at 24 volts.
