Description
The Allen-Bradley 1756-IT6I is an isolated thermocouple input module designed for the ControlLogix platform. This module provides six high-precision, isolated input channels specifically engineered for temperature monitoring applications. By utilizing isolated inputs, the module ensures enhanced noise immunity and protection against ground loops, making it suitable for demanding industrial environments where signal integrity is critical.
Features
- Six isolated thermocouple input channels for reliable temperature sensing.
- Supports a wide range of thermocouple types including B, C, E, J, K, N, R, S, and T.
- Includes one Cold Junction Compensation (CJC) sensor for accurate thermal measurement.
- Compatible with 1756-TBNH and 1756-TBSH removable terminal blocks for efficient field wiring.
- Optimized power consumption with a maximum dissipation of 4.3 Watts.

Installation Guidelines
- Ensure the ControlLogix chassis power is removed before inserting or removing the module to prevent electrical damage.
- The module should be seated firmly into the chassis slot; secure using the integrated locking mechanism.
- Use shielded thermocouple extension wire to minimize electromagnetic interference (EMI) and maintain signal accuracy.
- Proper grounding of the shield at the module end is recommended to reduce noise.
- Verify that the chosen terminal block (1756-TBNH or 1756-TBSH) is correctly wired according to the specific thermocouple polarity before applying power.
