1746-IV32 Allen-Bradley SLC 500 24VDC Input Module 32 Points

Product Overview

The Allen-Bradley 1746-IV32 is a high-density input module for the SLC 500 platform. It provides 32 discrete input points. These points operate on 24VDC source signals. The module organizes inputs into 4 isolated groups. Each group has 8 inputs. This design simplifies wiring and troubleshooting. The module supports a wide input voltage range. It works from 15 to 30VDC at 50°C. At 60°C, the range is 15 to 26.4VDC. The minimum on-state voltage is 15.0VDC. The maximum off-state voltage is 5.0VDC. This ensures clear signal distinction. Signal delays are fast. The turn-on delay is 3 ms. The turn-off delay is 8 ms. This module is ideal for monitoring sensors and switches. It is a key component for automation systems.

Application Scenarios

This module works in many industrial settings. Use it in manufacturing plants. It monitors limit switches and push buttons. It reads sensor outputs from proximity detectors. It works well in packaging machines. It fits into conveyor control systems. The module suits material handling applications. It is common in automotive assembly lines. It also works in food and beverage processing. The 32-point density saves rack space. The group isolation adds safety. It is perfect for distributed control systems.

Technical Specifications

The 1746-IV32 has specific electrical ratings. It draws 0.050 Amperes from the 5VDC backplane. Total heat dissipation is 0.25W. Each point dissipates a maximum of 0.2W. The module provides channel isolation from the backplane. This isolation is 1500 Volts AC for one minute. The input current is 5.1 mA at 24VDC. The off-state current is a maximum of 1.5 mA. The module operates in temperatures from 0°C to +60°C. Storage temperature ranges from -40°C to +85°C. It handles relative humidity from 5% to 95% without condensation. The module holds several agency certifications. These include UL, C-UL, CE, and C-Tick marks. It is rated for Class I, Division 2 hazardous locations.

Installation & Maintenance Guide

Install the module into any SLC 500 chassis slot. Ensure the backplane power is off. Align the module with the card guides. Push firmly until it seats. Tighten the top and bottom screws. Connect field wiring to the removable terminal block. Follow the wiring diagram for your group. Use copper wire rated for 75°C. Torque terminals to 0.8 Nm. Check all connections before powering up. Perform a visual inspection regularly. Keep the module free from dust and moisture. Do not remove the module while the system is live.
