The Allen-Bradley 1756-IT6I2 is an enhanced isolated thermocouple input module designed for the ControlLogix platform. This module provides six isolated input channels, specifically engineered to interface with various thermocouple types for high-precision temperature monitoring in industrial control environments.

Features

• Six isolated input channels for thermocouple temperature sensing.
• High-resolution 16-bit analog-to-digital conversion.
• Enhanced isolation to minimize signal noise and ground loop interference.
• Configurable input ranges including -12 to 78 mV and -12 to 30 mV.
• Compatible with standard ControlLogix backplane power requirements.

Technical Specifications

Installation Guidelines

• Ensure the ControlLogix chassis power is disconnected before installing or removing the module.
• Use a compatible Removable Terminal Block (RTB) such as the 1756-TBNH or 1756-TBSH for secure field wiring.
• Maintain proper grounding practices to protect against EMI; use shielded thermocouple cabling where necessary.
• Ensure adequate airflow within the enclosure to accommodate the 4.6W maximum power dissipation.
• Verify that the module is fully seated in the chassis slot and the locking latch is engaged.
