ALLEN BRADLEY 1794-IB32 Used Working FLEX I/O Digital Input

Product Overview

The Allen-Bradley 1794-IB32 (FLEX I/O) is a high-density 32-Point Digital Input Module designed to provide extensive monitoring capabilities in a compact, modular footprint. As part of the versatile FLEX I/O family, this module allows for the distributed collection of 24V DC signals from sensors, pushbuttons, and limit switches without the need for long, expensive home-run wiring to the main PLC. As a Used Working unit, it is an ideal solution for expanding existing ControlLogix, CompactLogix, or PLC-5 systems, offering a massive I/O count while occupying the same rack space as standard 8 or 16-point modules.

Key Features

• High-Density 32-Point Design: Provides 32 discrete input points in a single module, significantly reducing the required number of Flex I/O base units and backplane space.
• 24V DC Sink Inputs: Optimized for standard industrial 24V DC sourcing sensors (PNP), ensuring broad compatibility with modern field devices.
• Flexible Communication Integration: Compatible with various FLEX I/O adapters, including EtherNet/IP (1794-AENT), ControlNet (1794-ACN), and PROFIBUS (1794-APB).
• Input Filtering: Features integrated digital filtering to eliminate electrical noise and contact bounce, ensuring stable signal logic for the controller.
• Modular "Removal Under Power" (RIUP): Supports RIUP functionality, allowing the module to be replaced while the rest of the system remains operational, minimizing downtime.
• Grouped I/O Architecture: Organized into two groups of 16 inputs, simplifying common-terminal wiring and power distribution within the terminal base.
• Status Visualization: Equipped with 32 individual front-panel LED indicators for instantaneous visual confirmation of each input's logic state.

Item Condition (Used Working)

• Functional Status: Used Working. This module has been professionally bench-tested using a 1794-ASB adapter. All 32 input points have been toggled and verified for consistent logic reporting to the controller.
• Physical State: Clean industrial condition. The gold backplane pins are straight and free of oxidation. The plastic locking tabs are secure and functional.
• Technical Integrity: No "Module Fault" or "I/O Communication" errors were detected during the hardware handshake. The unit has been handled in an ESD-safe environment and cleared of industrial dust.
• Note: Professional installation is recommended. This module requires a compatible 1794 terminal base (e.g., 1794-TB32 or 1794-TB32S) for operation.
