Allen-Bradley 1771-NR Analog High Resolution Isolated PLC-5 Module

Allen-Bradley 1771-NR is an eight-channel, high-resolution, isolated analog input module for the PLC-5 family. It provides eight RTD/resistance-input channels (1 to 650 ohms) that feed isolated analog signals to the PLC-5 backplane, helping protect the controller from field voltage transients and common-mode noise. This module delivers 16-bit resolution on its inputs, is designed for installation in 1771 I/O racks within PLC-5 systems, and, as part of the PLC-5 high-resolution analog I/O family, typically completes a conversion in about 25 ms per module, making it suitable for temperature monitoring and other precise process measurements in industrial environments.
