Allen-Bradley 1771-NT1 PLC5 Analog Input Module

Product Overview

The Allen-Bradley 1771-NT1 is a high-resolution PLC5 analog input module engineered for precise industrial temperature and voltage measurements. It provides eight input channels compatible with thermocouples B, E, J, K, T, R, S, and millivolt signals up to ±105 mV.

This module integrates seamlessly into any 1771 I/O chassis and works with 1771 processors supporting Block Transfer instructions, allowing efficient data transfer to the controller’s memory. Users can configure multiple register blocks simultaneously for optimized performance.

Designed for critical temperature applications, the 1771-NT1 ensures accurate readings with input resolution down to 0.1°C per bit for specific thermocouples. Cold junction compensation and linearization follow IPTS-68 and NBS MN-125 standards for precise measurement.

Its robust construction supports industrial operating conditions while maintaining minimal backplane current consumption. Rack-mountable design and standard Allen-Bradley diagnostic procedures simplify installation, setup, and maintenance.
