Description
The AB 1756-IR6I is an Allen-Bradley ControlLogix Isolated RTD Input Module. It’s a component within the ControlLogix family of industrial programmable logic controllers (PLCs) manufactured by Rockwell Automation.
Product Description:
- The 1756-IR6I module is designed to receive and process analog signals from resistance temperature detectors (RTDs).
- RTDs are common sensors used in industrial applications to measure temperature.
- The module converts the RTD resistance values into usable temperature readings that the PLC can use for control and monitoring purposes.
Key Features:
- Six Isolated RTD Inputs: It can accommodate up to six individual RTD sensors.
- High Accuracy: Provides precise temperature measurements with an accuracy of ±0.1% of full scale.
- Wide Temperature Range: Supports a wide range of RTD temperature measurements, typically from -200°C to 800°C (-328°F to 1472°F).
- Fault Detection: Can detect and report faults in the RTD sensors or wiring.
- Easy Configuration: Configurable using Rockwell Automation’s RSLogix 5000 programming software.
Applications:
- Temperature Monitoring: Used in various industrial applications to monitor and control temperature, such as in heating and cooling systems, process control, and machinery monitoring.
- Data Acquisition: Acquiring temperature data from RTD sensors for logging, analysis, or supervisory control systems.
- Alarm Systems: Triggering alarms or warnings when temperature exceeds predefined limits.
Product Specifications (Refer to Allen-Bradley Datasheet for details):
- Input Range: Specific resistance range supported by the module for RTD sensors (e.g., Pt100, Cu100).
- Signal Resolution: The smallest change in temperature that the module can detect and represent.
- Update Rate: The frequency at which the module updates the temperature readings.
- Communication Protocol: The method by which the module communicates temperature data to the PLC (e.g., backplane communication).
