Allen-Bradley 1771-IR RTD Input Module Detailed Explanation
Product Overview
Allen-Bradley 1771-IR is an RTD(thermal resistor)input module designed for PLC-5 series controllers.It is used to convert the resistance value measured by the RTD sensor into a standardized digital signal for processing by the PLC,thereby realizing temperature measurement and control.
Main Functions
RTD Signal Acquisition:Acquires resistance signals from RTD sensors.
Signal Conversion:Converts analog resistance signals into digital signals.
Signal Processing:Linearizes the acquired signals and provides output in multiple temperature units.
Communication with PLC:Data transmission and control are achieved by connecting to the PLC-5 series controller.
Core Features
High Accuracy:Provides high-precision temperature measurement.
Flexibility:Supports multiple RTD types and temperature units.
Reliability:Industrial-grade design ensures long-term stable operation.
Easy to configure:Module parameters can be easily configured through programming software.
Application Scenarios
Temperature Control:Used in industrial process control systems to measure and control temperature.
Environmental monitoring:used to monitor the ambient temperature.
Equipment protection:used to monitor the temperature of the equipment to prevent overheating.
