Description

Product Overview

The Allen-Bradley 1794-IV32 is a high-density 32-channel discrete input module for the Flex I/O platform. It accepts 24V DC nominal sourcing inputs across a 19.2-31.2V DC range. With configurable filter times and 32 yellow status indicators, it delivers reliable signal acquisition for distributed I/O systems.

Core Functionality

The 1794-IV32 interfaces discrete field devices such as switches, auxiliary contacts, and sensors with PLC controllers. It draws 40mA at 5V DC from the FlexBus and communicates via a Flex I/O adapter. The module offers eight configurable input filter times from 0.25ms to 32ms, eliminating false activation from noise or contact bounce. The default filter time is 0.25ms.

Installation Guide

Align the module keyswitch with the 1794 mounting base and turn until pins align with base connectors. Use the alignment bar and groove for proper positioning. Press the module until the latching mechanism locks in place. Connect 24V DC sourcing field devices. Select appropriate filter time (0.25-32ms) based on signal characteristics. Ground the module through the zinc-plated DIN rail to chassis ground. Install indoors only, at altitudes up to 6562 feet.

Engineering Advantages

This module delivers 32 input channels in a compact 3.7 x 3.7 x 2.7 inch form factor for high-density installations. Eight configurable filter times adapt to different signal environments. 40mA FlexBus current draw minimizes power consumption. Compatibility with PLC5, SLC 500, CompactLogix, and ControlLogix controllers ensures broad system integration. Pollution Degree 2 and Overvoltage Category II ratings support industrial environments.
