Product Description

Description

The Allen-Bradley 1746-IV32 is a high-density sink/source DC input module designed for the Allen-Bradley SLC 500 modular hardware system. Engineered for applications where panel space is at a premium, this module provides 32 current-sourcing digital inputs operating within a 24VDC nominal voltage category. It is an ideal solution for industrial automation environments requiring reliable discrete signal monitoring across multiple channels.

This module features a 40-pin MIL-C-83503 type header designed to connect easily with removable wiring connectors or pre-wired Bulletin 1492 interface solutions. Its compact high-density architecture helps reduce overall enclosure footprints while maintaining robust performance standards across standard industrial temperature ranges.

Features

  • 32 digital input channels configured for 24VDC current-sourcing operation
  • High-density design engineered specifically for SLC 500 system racks
  • Equipped with a 40-pin MIL-C-83503 type header for flexible wiring options
  • Compatible with Bulletin 1492 pre-wired interface modules and cables
  • Low backplane current draw of 50mA at 5VDC
  • Fast signal response times with a maximum of 3ms for both ON and OFF transitions

Applications

  • Discrete manufacturing and assembly lines
  • Process control and monitoring systems
  • Machine tool automation
  • Material handling and conveyor systems

Connections / Interfaces

The 1746-IV32 module utilizes a front-access 40-pin MIL-C-83503 type header. Users can terminate field wiring using a removable wiring connector such as the 1746-N3, or deploy Bulletin 1492 interface modules with pre-wired cables to streamline panel installation and reduce wiring errors.

Installation Guidelines

This module slots directly into any available I/O slot of an SLC 500 chassis. Ensure that power to the chassis is removed before inserting or removing the module. Secure the module using the top and bottom chassis retaining screws. Verify all field wiring connections against electrical schematics before restoring power to the control system.
