1492-IFM40F-F24AD-4 | Allen Bradley | 1492 Wiring System Fusible Interface Module

Product Overview

The Allen Bradley 1492-IFM40F-F24AD-4 serves as a high-density pre-wired solution for industrial I/O interfacing. This module simplifies the connection between field devices and PLC I/O cards by integrating fusing and terminal blocks into a single DIN-rail mounted footprint. We supply this unit as 100% Brand New and Factory Original, ensuring peak electrical conductivity and circuit protection for your critical control systems.

Technical Specifications

The 1492-IFM40F-F24AD-4 manages high-density wiring through the following technical parameters:

Engineering Advantages

• Advanced Diagnostics with Low Leakage: The integrated LED circuit identifies blown fuses instantly without triggering false "ON" states in high-impedance PLC inputs. The ultra-low leakage current (0.05 mA) prevents the common industrial issue where indicator lights keep digital inputs active even after a fuse failure.

• Reduced Wiring Errors: The 40-pin header allows for a direct, keyed cable connection to the PLC I/O module. This "plug-and-play" architecture eliminates point-to-point wiring mistakes, slashing commissioning time and reducing labor costs during panel assembly.

• Group Isolation Flexibility: By organizing the 40 pins into 4 isolated groups, this module allows engineers to mix different power sources or voltage potentials on a single interface. This prevents ground loops and improves total system noise immunity.

• Field-Side Fusing Efficiency: Individual fusing for each channel protects sensitive PLC output and input circuits from field-side short circuits or overcurrent events. This localized protection ensures that a single field fault does not disable an entire I/O card.

FAQs

• Is this 1492-IFM40F-F24AD-4 unit genuinely new?

  Yes. We guarantee that every unit is 100% Brand New and arrives in its original factory packaging. It has never been installed, wired, or used in a live environment.

• What type of fuses does this module require?

  The module typically utilizes standard glass or ceramic small-dimension fuses. You must select the fuse amperage based on your specific load requirements and the maximum current rating of the 1492 wiring system cable you are using.

• Can the LEDs operate on AC control circuits?

  No. This specific model features a 24V DC LED circuit. Applying AC voltage to the indicator circuit will damage the LEDs. Always verify your control voltage polarity before energizing the module.

• Does the unit include the pre-wired cable?

  This part number refers to the Interface Module only. You must purchase the 1492-CABLE series (40-pin) separately, selecting the length and connector type that matches your specific Allen Bradley PLC I/O card.
