1756-IT6I2 Functional Description    

The Allen-Bradley 1756-IT6I2 is a high-performance analog input module designed for precise temperature measurement in industrial environments. This module supports up to six individually isolated thermocouple inputs and two cold junction compensation (CJC) inputs, compatible with thermocouple types B, E, J, K, R, S, T, N, C, D, and L (TXK/XK). Installed within a ControlLogix chassis, it requires a 1756-TBNH Removable Terminal Block for proper wiring.

The 1756-IT6I2 ControlLogix Analog Input Module provides exceptional accuracy with input ranges of -12 to 78 microvolts (1.4 microvolts per bit) and -12 to 30 mV (0.7 microvolts per bit), featuring a 16-bit resolution. With a high input impedance exceeding 10 MOhms and overvoltage protection up to 120 Volts AC/DC, it ensures robust and reliable operation. It also boasts ITS-90 thermocouple linearization, 0.5 microvolts/°C offset drift, and a settling time of over 80 milliseconds.

Additional features of the Allen-Bradley controllogix 1756-IT6I2 include cold junction compensation, real-time sampling, open circuit detection, and support for multiple data formats like integer and floating-point modes. Its advanced diagnostics enable under-range/over-range detection, rate alarms, process alarms, and noise rejection of 60 dB (normal mode) or 160 dB (common mode).

Compatible with standalone or distributed ControlLogix systems, the 1756-IT6I2 Digital Sourcing I/O Module supports seamless integration into computer-based control setups. By leveraging its data table mapping capabilities, users can implement dynamic process control algorithms, alarms, and real-time monitoring. This module ensures reliable and efficient temperature data acquisition in demanding applications.
