1794-IF2XOF2I | Allen-Bradley | FLEX I/O Isolated Analog Input/Output Module

Product Overview

The Allen-Bradley 1794-IF2XOF2I functions as a high-density analog combo module within the FLEX™ I/O platform. It provides two isolated inputs and two isolated outputs, allowing simultaneous signal acquisition and control within a single footprint. By utilizing Sigma Delta conversion technology, this module ensures superior signal integrity and noise rejection for critical process loops. We offer this unit as 100% Brand New and original factory equipment, guaranteeing the highest level of performance for your automated systems.

Technical Specifications

The following table details the high-performance hardware parameters of the 1794-IF2XOF2I module:

Engineering Advantages

• Channel-to-Channel Isolation: The 1794-IF2XOF2I features full galvanic isolation. This architecture prevents ground loops and protects your controller from high-voltage transients on the field side, significantly increasing system availability.

• Precision Signal Processing: The integrated Sigma Delta converters filter out high-frequency industrial noise. This ensures that the PLC receives clean, accurate data even in environments saturated with electromagnetic interference (EMI) from variable frequency drives (VFDs).

• FLEX™ System Scalability: This module mounts directly onto a 1794 terminal base. The design allows "Removal and Insertion Under Power" (RIUP), enabling technicians to replace modules without shutting down the entire backplane, thus minimizing production downtime.

• Rugged Environmental Tolerance: Built to meet IEC 60068-2-30 standards, the module maintains operational stability in humid (up to 95%) and high-vibration (5g) industrial settings, typical of heavy manufacturing and oil & gas applications.

FAQs

• Is this 1794-IF2XOF2I unit used or refurbished?

  No. We supply exclusively 100% Brand New units in original Allen-Bradley factory packaging to ensure full compliance with your facility's reliability standards.

• Do I need to calibrate the module before the first installation?

  The module arrives factory-calibrated for 150 Hz, 300 Hz, and 600 Hz. While it is ready for immediate deployment, you can perform field recalibration via the control software if your specific application requires custom offset adjustments.

• What is the significance of the Keyswitch Position 5?

  The keyswitch position ensures that you only plug the module into a correctly keyed terminal base. This mechanical safeguard prevents electronic damage caused by inserting an analog module into a base wired for digital or high-voltage signals.

• Can this module handle mixed signal types simultaneously?

  Yes, the 1794-IF2XOF2I manages both input (sensing) and output (commanding) tasks through its isolated channels, making it an ideal choice for PID loops where space on the DIN rail is limited.
