Allen Bradley 1771-IE/1 — 8 bit Analog Input module.

The 1771-IE/1 is an 8-bit analog input module manufactured by Allen Bradley. This module is designed to convert analog signals into digital data for further processing and control within a compatible Allen Bradley programmable logic controller (PLC) system.

The 1771-IE/1 module offers support for up to eight analog input channels, allowing for the connection of various sensors and devices that generate analog signals. It utilizes a high-speed, successive approximation analog-to-digital converter (ADC) to provide accurate and reliable conversion of these signals.

With its 8-bit resolution, the 1771-IE/1 module can effectively convert analog signals into 256 digital values. This provides adequate granularity for most industrial applications where precise control and monitoring are required.

The module can accept a wide range of input signals, including voltage, current, and temperature. It features a configurable input range and supports both single-ended and differential input configurations.

The 1771-IE/1 module is designed for integration into the Allen Bradley 1771 I/O chassis. It communicates with the PLC system through the backplane, utilizing the common 1771 I/O communication protocol.
