1492-ACABLE080UB | Allen Bradley | 1492 Wiring System Pre-Wired Cable

Product Overview

The Allen Bradley 1492-ACABLE080UB functions as a high-performance, pre-terminated wiring solution designed to link 1756 ControlLogix I/O modules to 1492 Interface Modules (IFMs). This 8.0-meter cable assembly eliminates manual point-to-point wiring, ensuring a secure and error-free connection between the controller and field-side terminations. We supply this cable as 100% Brand New and Factory Original, providing a reliable, long-reach solution for complex control cabinet architectures.

Technical Specifications

The 1492-ACABLE080UB utilizes industrial-grade conductors and molded connectors to maintain signal fidelity across its entire length:

Engineering Advantages

• Elimination of Termination Errors: The 1492-ACABLE080UB features factory-molded and keyed connectors. This hardware design prevents incorrect pin alignment and eliminates the common failure point of loose manual terminations at the PLC swing-arm.

• Optimized for Large-Scale Enclosures: The 8-meter length solves the challenge of connecting PLC racks to remote interface modules in wide control suites. It allows engineers to centralize the Logix chassis while distributing the 1492-IFM blocks closer to the machine entry points.

• Rapid Commissioning: By utilizing a pre-wired harness, electrical technicians reduce installation time by up to 75% compared to traditional wire-and-ferrule methods. This speed is critical during high-pressure system retrofits and plant-wide upgrades.

• Superior Signal Continuity: Every conductor undergoes factory continuity testing. The factory-crimped terminals resist the oxidation and vibration-induced loosening that often plague field-wired terminal blocks over years of operation.

FAQs

• Is this 1492-ACABLE080UB cable genuinely brand new?

  Yes. We guarantee this product is 100% Brand New and arrives in its original factory-sealed coil. We do not supply used or "pull-off" cables, ensuring the internal conductors have no fatigue from previous installations.

• What does the "UB" suffix signify in the part number?

  The "UB" suffix identifies the specific wiring pinout mapping between the 40-pin PLC connector and the IFM connector. You must match this suffix to the specific 1492-IFM module and 1756 I/O card combination listed in the Allen Bradley wiring system selection guide to ensure proper signal routing.

• Can I cut this cable to a shorter length if needed?

  While technically possible, we strongly advise against it. The cable features factory-terminated connectors on both ends. Cutting the cable voids the warranty and destroys the integrity of the molded connection. If you require a shorter run, please select the 1492-ACABLE010UB (1.0m) or 025UB (2.5m) models.

• Does this cable require a specific 1756 Removable Terminal Block (RTB)?

  No. This cable replaces the standard RTB. The 40-pin connector on the 1492-ACABLE080UB snaps directly onto the front of the 1756 I/O module, acting as the interface itself.
