1756-IT6I Analog thermocouple module Supports installation to any ControlLogix chassis

Manufacturer Rockwell Automation
Brand Allen Bradley
Part Number/Catalog number 1756-IT6I
Series ControlLogix
Module Type Analog thermocouple module
The Allen-Bradley 1756-IT6I is a ControlLogix analog input module. The input module is specially designed for thermocouple and millivolt input for temperature measurement. The module supports installation into any ControlLogix chassis, whether local or remote I/O racks. It is compatible with any CotnrolLogix processor and communication module.

The module is compatible with B, E, J, K, R, S, T, N, C, D, L (TXK/XK) type thermocouples. For the high resolution range, the module has a valid input range of -12 to 78 mV and -12 to 30 mV. The module has a resolution of 16 bits, 1.4? V/ bit (typical value) for -12... 78 mV and 0.7? V/bit high resolution range for -12... 30 millivolts besides, for -12... The 30 mV, low signal and user counts are 15.80323 mV and -32768 counts, while the high signal and user counts are 31.396 mV and 32767 counts. For -12... The 78 mV, low signal and user counts were -15.15836 mV and -32768 counts, while the high signal and user counts were 79.241 mV and 32767 counts.

Module scan times are relatively fast and vary depending on data format and signal type. For millivolt inputs, the floating point scan time is a 25 ms minimum, while the integer scan time is a 10 ms minimum. For floating-point format, the scan time is more than 50 milliseconds,

Compatible data formats are integer mode, left-justified, 2s complement, and IEEE 32-bit floating point.

Allen-Bradley 1756-IT6I is a temperature detection simulation module. It has one six (6) individually isolated thermocouple input channels. It requires 1756-TBNH or 1756-TBSH detachable Terminal (RTB) for signal wiring. For local CJC, it has an accuracy of +/-0.3 to 3.2 degrees Celsius, depending on the channel, and for remote CJC, it has an accuracy of +/-0.3 degrees Celsius.
