ALLEN BRADLEY 1769-IF8 Used Working CompactLogix Analog Input

Product Overview

This lot includes two (2) Allen-Bradley 1769-IF8 Series A high-density Analog Input Modules. These modules are designed for use with CompactLogix controllers or as distributed I/O in MicroLogix 1500 systems. Each module provides 8 high-resolution differential or single-ended inputs, allowing for the precise measurement of voltage and current signals from field transmitters. As a Used Working lot, these modules are an excellent solution for system expansions or as ready-to-install spares for critical process control loops in manufacturing and water treatment applications.

Key Features

• High-Density 8-Channel Design: Each module supports 8 analog inputs, significantly reducing the hardware footprint and rack space required for multi-sensor setups.
• Flexible Input Ranges: Individually configurable for multiple voltage (±10V, 0-10V, 0-5V, 1-5V) and current (0-20mA, 4-20mA) ranges.
• High-Resolution Accuracy: Features 16-bit unipolar or 15-bit plus sign bipolar resolution, ensuring high-fidelity data for sensitive PID control loops.
• Differential/Single-Ended Support: Can be wired for differential signals to minimize electrical noise or single-ended signals to maximize channel count.
• Series A Hardware: Reliable original hardware revision compatible with standard 1769 backplane architectures and RSLogix 500/5000 software.
• Removal Under Power (RIUP): Allows for the replacement of modules while the system is powered (with proper safety considerations), reducing system downtime.
• Digital Filtering: Built-in selectable filters help stabilize readings from noisy industrial environments.

Item Condition (Used Working)

• Functional Status: Used Working. Both modules in this lot have been professionally bench-tested. Every input channel has been verified for accuracy using a signal generator.
• Physical State: Clean industrial condition. The bus connectors are clean and free of oxidation. Both modules include their removable terminal blocks.
• Technical Integrity: No "Module Fault" or "I/O Error" status was detected during backplane communication tests. The units have been cleared of previous configuration data.
• Note: Professional installation is recommended. Ensure the 1769-IF8 modules are placed within the power supply distance rating of your CompactLogix rack to ensure stable operation.
