Allen-Bradley 1756-IT16 ControlLogix 16-Point Thermocouple Input Module (B/C/E/J/K/N/R/S/T Type)
The Allen-Bradley 1756-IT16 is a ControlLogix 16-point thermocouple input module supporting thermocouple types B, C, E, J, K, N, R, S and T. It provides 16 non-isolated channels with a -100…+100 mV input range, 24-bit resolution (0.01 µV/count) and dual cold junction compensation (CJC). Ideal for high-density temperature monitoring in process control and machine applications. Technical data sourced directly from the official Rockwell Automation 1756-IT16 product page and ControlLogix system catalog. Supplied by SHLY-PLC, an independent industrial automation distributor; each unit undergoes visual inspection and functional testing before shipment. Contact our team for compatibility verification.
