Description

The Allen-Bradley 1746-IV32 is a high-density digital input module engineered for the SLC 500 programmable controller platform. It provides 32 discrete sourcing input points within a single-slot module, offering an efficient solution for applications requiring high I/O density in space-constrained chassis environments. This module is designed to interface with field devices that sink current to the common return, supporting flexible configuration across four isolated groups of eight points each.

Features

High Density: 32 sourcing inputs in a single-slot footprint.
Isolated Grouping: Four isolated groups of eight points allow for multiple power sources or voltage references.
Compatibility: Fully integrated with the Allen-Bradley SLC 500 system architecture.
Connectivity: Utilizes a 40-pin high-density connector for efficient field wiring via pre-wired cable assemblies or 1492 interface modules.

Applications

This module is widely used in industrial automation systems for monitoring discrete field signals such as proximity switches, pushbuttons, and limit switches. Its high-density design is particularly effective in large-scale control panels where chassis slot availability is limited.

Installation Guidelines

Power Down: Always disconnect backplane power before inserting or removing the module from the chassis.
ESD Handling: Use proper electrostatic discharge (ESD) grounding procedures when handling the module to prevent damage to internal circuitry.
Wiring: Ensure the use of appropriate 40-pin cable assemblies. Verify that the field device common return is correctly matched to the sourcing input requirements.
Environment: Install in an enclosure rated for the intended environment, ensuring adequate airflow to maintain operating temperatures within the specified 0-60 degC range.
Grounding: Ensure the SLC 500 chassis is properly grounded according to local electrical codes to minimize EMI interference.

FAQ

What type of field wiring is required for the 1746-IV32?

Because this is a high-density module, it does not use standard screw terminals. It requires a 40-pin high-density connector, typically interfaced using a pre-wired cable assembly or a 1492-style terminal block interface module.

Can I use different power sources for the inputs?

Yes. The 32 inputs are divided into four isolated groups of eight points each, allowing you to use different power sources or voltage references for each group, provided they remain within the 15-30V DC range.
