Allen-Bradley 1756-IRT8I Input Module

The Allen-Bradley 1756-IRT8I is an 8-channel input module for the ControlLogix 5560 series Programmable Automation Controllers (PACs) by Rockwell Automation. It functions as a versatile interface for acquiring temperature, resistance, and voltage measurements from various sensors.

Overview:
Supported Input Types:
Resistance Temperature Detectors (RTDs)
Thermocouples
Resistance measurements (2-wire and 4-wire)
Millivolt measurements
Number of Channels: 8, individually configurable
Isolation: Each channel is electrically isolated from each other and the backplane, preventing ground loops and noise interference.
Communication: Connects to the ControlLogix PAC through the backplane

Key Features:
Wide range of supported sensors: Accommodates various temperature, resistance, and voltage sensing needs.
Individual channel configuration: Each channel can be independently set for different sensor types, input ranges, and filtering options, providing flexibility for diverse applications.
High accuracy: Delivers accurate and reliable measurement data.
Cold junction compensation: Ensures accurate temperature readings for thermocouple measurements.
Linearization: Linearizes non-linear sensor outputs for easier data interpretation.
LED indicators: Provide visual status for each channel, including power, sensor type, and open/short circuit conditions.

Applications:
Temperature monitoring and control: Used in various industrial processes, HVAC systems, power generation, and scientific research to monitor and control temperature.
Resistance measurement: Applied in applications like level measurement, strain gauge monitoring, and motor winding resistance testing.
Millivolt measurement: Used for measuring battery voltage, pressure transducers, and other low-voltage signals.
