A-B 1756-IRT8I
The Allen-Bradley 1756-IRT8I module is a high-resolution analog input module from the Allen-Bradley brand of Rockwell Automation. It belongs to the ControlLogix series and is mainly used to convert external high-precision analog signals (such as RTD, thermocouple, millivolt, etc.) into digital signals for PLC accurate measurement and control. The module is particularly suitable for applications where high precision temperature measurement is required.
Main function
High resolution analog input: Provides 8 independent high resolution analog input channels for accurate measurement of various types of temperature sensor signals.
Signal conditioning: Built-in signal conditioning circuit, can be directly connected to RTD, thermocouple, millivolt and other sensors, no peripheral circuit.
Flexible configuration: Software can be used for flexible configuration, including input range, filtering, and fault detection.
Redundancy design: Redundant modules are available to improve system reliability.
