1769 Compact I/O | Allen-Bradley | 1769-IT6 ser A Thermocouple Mv Input Module 6chnl AB

Product Description:
The Allen-Bradley 1769-IT6 is a 6-channel thermocouple and millivolt input module designed for use with CompactLogix or MicroLogix 1500 systems. It provides high-resolution temperature input for thermocouples or low-voltage millivolt sensors. The module includes integrated cold junction compensation (CJC) and supports a wide range of thermocouple types, making it suitable for process and temperature monitoring applications.

Key Features:

• 6 differential input channels

• Supports thermocouple types: J, K, T, E, R, S, B, N

• Also accepts low-level analog signals (±50 mV, ±100 mV)

• Built-in cold junction compensation (CJC)

• 16-bit resolution

• Configurable input filtering and scaling

• Diagnostic capabilities for open thermocouple detection

• Compatible with CompactLogix and MicroLogix 1500 controllers

• Uses RSLogix 5000 or Studio 5000 for configuration
