Product Details
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.

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.

Tech & Buying Guide
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
