Allen-Bradley 1746-IB32 SLC 500 Digital DC Input Module

Quantity

Product Description

Description

The Allen-Bradley 1746-IB32 is a high-density current sinking DC input module designed specifically for the Allen-Bradley SLC 500 programmable logic controller platform. Ideal for applications where panel space is at a premium, this compact module provides a reliable interface for discrete 24V DC field signals while helping to optimize system footprint and overall cabinet wiring efficiency.

Engineered for industrial automation environments, the 1746-IB32 features multiple point commons to facilitate flexible wiring configurations. When integrated into an SLC 500 chassis, it delivers fast, dependable signal processing with robust optical isolation between the field side and the backplane, helping to protect sensitive control hardware from electrical transients.

Features

  • High-density design featuring 32 discrete DC input points in a single modular slot
  • Current sinking (Type B) input configuration compatible with various 24V DC sensors and switches
  • Six isolated common terminals organized across the input points for flexible circuit grouping
  • Nominal input voltage of 24V DC with an operating range suitable for standard industrial power supplies
  • Low backplane power consumption drawing 50 mA from the 5V rail and 0 mA from the 24V rail
  • Fast signal on and off delay times of 3 ms maximum for responsive machine and process control

Applications

  • Discrete manufacturing and assembly line control
  • Packaging and material handling systems
  • Machine tool automation and robotic cell integration
  • Process skids requiring high-density digital monitoring

Technical Specifications
