Allen-Bradley 1492-AIFM16-F-3 Analog Interface Module

Description

The Allen-Bradley 1492-AIFM16-F-3 is a fusible 16-channel analog input interface module designed for programmable controller wiring systems. It features integrated 24V DC blown fuse indicators and provides 3 terminals per channel for field-side signal termination. The module incorporates fuse holders for channel protection and DIP switches that allow unused inputs to be jumpered to module common on compatible analog modules.

Features

• Fusible 16-channel input architecture with 3 terminals per channel.
• Integrated 24V DC blown fuse indicators for rapid diagnostic field status.
• Configurable DIP switches to jumper unused inputs to module common in the closed (ON) position.
• Eighteen field-side shield terminals jumpered together internally and tied to the D-shell housing.
• On-board fuse holders accommodating $5\times20\text{ mm}$ fuses.

Applications

• Analog signal termination and channel protection for programmable controller I/O systems.
• Field sensor wiring integration requiring individual channel fusing and blown fuse indication.

Technical Specifications

Installation Guidelines

• Compatibility: Ensure field signal voltage and current ratings do not exceed the module specifications.
• Fusing: Install 5 × 20 mmfuses into the integrated fuse holders before commissioning; do not exceed 2 A per input channel or 12 A total for the entire module.
• Power Source Isolation: Note that fuse clips and blown fuse indicators connect internally to a single power source field-side terminal; all connected inputs must reference the same power source.
• Unused Inputs Configuration: For analog modules supporting unused input jumpering, set the corresponding DIP switches to the ON position to connect unused inputs to module common.
• Shielding: Connect cable shields to the designated field terminals to utilize the internal ground loop to the D-shell housing.
