Description
Product Description
The 1756-IT6I is a multi-channel thermocouple and millivolt analog input module designed for the Allen-Bradley ControlLogix platform. This module features six individually isolated input channels and integrated cold junction compensation (CJC), enabling precise temperature acquisition in demanding industrial environments.
Designed for high-accuracy thermal process monitoring, the Allen-Bradley 1756-IT6I supports a broad range of industry-standard thermocouple sensors including B, C, D, E, J, K, L, N, R, S, and T types. The module also accepts low-level millivolt signals for specialized measurement applications.
With 16-bit resolution, isolated channel architecture, and flexible floating-point or integer data processing, the module is suitable for critical temperature monitoring systems where signal integrity and electrical noise immunity are essential.
