Allen Bradley 1492-XIM2024-16RF 1492 Wiring System Expander Interface Module

Product Overview

The Allen Bradley 1492-XIM2024-16RF serves as a high-density expander interface module within the 1492 Digital Wiring System. It bridges the gap between PLC output modules and high-current field devices by providing 16 integrated relay channels. This module simplifies cabinet architecture by consolidating interposing relays into a single, compact DIN-rail footprint. We provide this unit as 100% Brand New original stock, ensuring factory-certified safety and performance for mission-critical switching applications.

Technical Specifications

The 1492-XIM2024-16RF utilizes a robust 20-pin connection to manage high-amperage loads across multiple relay pairs.

Engineering Advantages

• High-Amperage Capacity: This module handles a peak total current of 96 Amps across the unit. It manages high-inrush loads effectively, allowing engineers to switch heavy solenoids and motor starters without risking backplane damage or premature component failure.

• Hazardous Location Certification: The T3C temperature code rating permits installation in specific hazardous environments. This certification ensures the module maintains safe surface temperatures during continuous high-load operation, a critical requirement for oil, gas, and chemical processing facilities.

• Simplified Troubleshooting: Integrated indicator circuits draw only 2 mA while providing clear visual feedback of relay states. Technicians identify failed field-side components instantly without opening the logic circuit, which drastically reduces MTTR (Mean Time To Repair).

• Pre-Wired Efficiency: The 20-pin header interfaces directly with 1492-series pre-wired cables. This architecture eliminates point-to-point manual wiring, prevents cross-connection errors, and shrinks the total labor time required for control panel commissioning.

FAQs

• What is the primary function of the "Expander" designation for this module?

  The 1492-XIM2024-16RF functions as an expansion point for existing wiring systems. It allows the user to scale up the number of interposing relays available to a single PLC output card, utilizing the 20-pin header to distribute 24V DC control signals efficiently across 16 channels.

• Does this module support both AC and DC field loads?

  While the relay coils require 24V DC to energize, the mechanical relay contacts provide dry-contact switching. This allows you to control a variety of field-side voltages, provided the current does not exceed the 10A peak circuit limit or the 12A peak relay pair limit.

• How does the T3C rating impact panel ventilation requirements?

  The T3C code indicates that the module remains within safe temperature limits for specific combustible atmospheres. However, because the module handles up to 96A total current, you must ensure adequate cabinet airflow to prevent localized heat buildup, especially when switching multiple high-current loads simultaneously.

• Can I replace individual relays if a single channel fails?

  This specific 1492-XIM module features integrated relay components to maximize density and vibration resistance. If a channel fails, you generally replace the module to ensure the integrity of the factory-certified internal busbars and the T3C safety rating.
