Description

The Allen-Bradley 1746-IM16 is a 16-point digital AC input module designed for use with the SLC 500 programmable logic controller system. This module provides a reliable interface for high-voltage AC field devices, converting 200-240V AC input signals into logic-level signals compatible with the SLC 500 processor. It is engineered for industrial environments requiring robust signal monitoring and high-density I/O configurations.

Features

  • 16 isolated input points for flexible wiring configurations.
  • Compatible with 200-240V AC nominal input voltage ranges.
  • Designed for integration within the standard SLC 500 chassis.
  • Includes status indicators for each input channel for simplified diagnostics.
  • Optical isolation between the field-side and the backplane for enhanced system protection.

Applications

This module is widely utilized in industrial automation systems for monitoring high-voltage AC limit switches, pushbuttons, and auxiliary contacts. It is standard in manufacturing, process control, and material handling applications where SLC 500 controllers are deployed to manage AC-powered field instrumentation.

Installation Guidelines

  • Ensure the SLC 500 chassis power is disconnected before installing or removing the module to prevent electrical damage.
  • Slide the module into the desired slot in the chassis and secure it using the integrated locking tab.
  • Use appropriate shielded cabling for input signals to minimize electromagnetic interference (EMI) in high-noise environments.
  • Verify that field wiring matches the terminal assignment diagram provided in the SLC 500 installation manual.
  • Maintain adequate clearance around the module to ensure proper ventilation and cooling within the control cabinet.
  • Follow standard ESD (Electrostatic Discharge) precautions when handling the module to protect internal components.

FAQ

What is the primary function of the 1746-IM16?

The 1746-IM16 is an AC input module that detects 200-240V AC signals from field devices and transmits that status to the SLC 500 processor for logic execution.

Is this module compatible with other SLC 500 series modules?

Yes, the 1746-IM16 is designed to be installed in any available slot of an SLC 500 I/O chassis, provided the power supply capacity is sufficient for the total system load.
