Allen-Bradley 1756-IT6I Thermocouple Isolated Input Module

The Allen-Bradley 1756-IT6I is a ControlLogix 6-channel isolated thermocouple input module (20-pin) designed for six independently isolated thermocouple inputs in a single slot. It accepts a wide range of thermocouples (B, E, J, K, R, S, T, N, C, D, L) and provides two input ranges (-12 to 78 mV standard, -12 to 30 mV high‑resolution) at 16-bit resolution (1.4 μV/bit standard, 0.7 μV/bit high‑resolution), with a single cold-junction compensation (CJC) channel. Electrical isolation is 250 V continuous between inputs and the backplane. As part of the 1756 IT6I family, firmware revision 1.12 is noted in Rockwell documentation, and the module was discontinued by Rockwell on March 31, 2017.
