Overview

The Allen-Bradley 1771-IXE is an analog input/output module designed for use with Allen-Bradley PLC-5 programmable logic controllers (PLCs). It allows the PLC to interface with a wide range of analog signals, including voltage and current, and provides flexibility for process control applications. This module provides both input and output capabilities, making it useful in applications that require monitoring and control of analog signals.
