1794-IB16XT FLEX I/O Extended Temperature Digital Input Module | Allen-Bradley

Product Overview

The Allen-Bradley 1794-IB16XT serves as a high-performance, 16-point digital DC input module specifically engineered for the FLEX I/O platform. The "XT" designation signifies its Extended Temperature capability, allowing the module to operate reliably in extreme thermal conditions that would cause standard industrial hardware to fail. It interfaces 24V DC field-side signals—such as sensors, switches, and encoders—directly to the distributed I/O network. We supply this unit as 100% Brand New and Original, ensuring your critical infrastructure benefits from the full ruggedized lifespan of the XT series.

Part Number Breakdown

The 1794-IB16XT follows a specific nomenclature for the FLEX I/O line:

• 1794: Identifies the FLEX I/O Product Family.

• IB: Indicates a Digital DC Sinking Input Module.

• 16: Specifies the number of input channels (16 Points).

• XT: Denotes Extended Temperature and ruggedized coating for harsh environments.

Technical Specifications

The 1794-IB16XT thrives in demanding environments while maintaining precise logic detection:

Engineering Advantages

The 1794-IB16XT provides specific solutions for high-stakes industrial applications:

• Thermal Resilience: Standard modules often fail at 55°C. The XT hardware utilizes high-grade components and specialized heat dissipation to maintain logic integrity up to 70°C, making it ideal for outdoor enclosures or desert-climate installations.

• Conformal Coating Protection: These modules frequently include a protective coating that resists chemical contaminants, humidity, and airborne particulates. This prevents corrosion on the PCB and ensures the 16 input channels remain stable over years of service.

• Compact High-Density I/O: The module packs 16 points into a small 7.1cm footprint. This density allows for significantly smaller control cabinets, reducing the overall cost of the enclosure and cooling hardware.

• Simplified Troubleshooting: Bright status indicators on the front panel provide real-time feedback for each input channel. Technicians can identify field-side wiring faults instantly without opening a laptop or accessing the PLC software.

FAQs

Can I use the 1794-IB16XT in a standard FLEX I/O rack?

Yes. The 1794-IB16XT maintains full physical and electrical compatibility with standard 1794 terminal bases and adapters. However, to benefit from the extended temperature rating, you must ensure the surrounding components (terminal base and adapter) also carry an XT rating.

What terminal bases are compatible with this module?

This module typically installs onto 1794-TB3, 1794-TB3S, or 1794-TBN bases. For harsh environments, we recommend utilizing the XT-rated versions of these terminal bases to match the module’s environmental specifications.

How does this module handle vibration?

The 1794-IB16XT meets rigorous industrial vibration and shock standards. The internal components are secured with additional bonding to prevent mechanical fatigue in applications involving heavy machinery or mobile equipment.

Is this a "New-Old-Stock" (NOS) item or current production?

We sell this unit as 100% Brand New, recently manufactured original stock. Unlike refurbished units, our brand-new XT modules ensure that the internal electrolytic capacitors and sensitive semiconductors have zero prior thermal stress.
