Allen Bradley 1492-ACABLE025UB ControlLogix Analog I/O Pre-Wired Cable

Product Overview

The Allen Bradley 1492-ACABLE025UB functions as a high-integrity, pre-wired cabling solution specifically engineered for the ControlLogix® 1756 platform. This 2.5-meter analog cable bridges the gap between 1756 Analog I/O modules—including RTD and Thermocouple inputs—and 1492 Interface Modules (IFMs). It eliminates the need for manual, point-to-point terminal block wiring, drastically reducing commissioning time. We supply this product as 100% brand new and original, ensuring optimal signal shielding and mechanical durability for your mission-critical process loops.

Technical Specifications

The 1492-ACABLE025UB utilizes industrial-grade conductors to maintain analog signal precision:

Engineering Advantages

• Elimination of Wiring Errors: The pre-terminated connectors on the 1492-ACABLE025UB ensure a 1-to-1 pin mapping between the PLC and the interface module. This architecture prevents costly cross-wiring mistakes common in manual field terminations.

• Superior EMI/RFI Shielding: Engineered specifically for sensitive analog signals, this cable utilizes advanced shielding techniques to mitigate electromagnetic interference. This ensures that RTD and Thermocouple data remains accurate and stable even in environments with high-frequency drive noise.

• Rapid System Deployment: Utilizing this 2.5m cable replaces hours of traditional hand-wiring. Engineers simply plug the cable into the 1756 module and the corresponding IFM, cutting labor costs and accelerating the overall panel build schedule.

• Industrial-Grade Strain Relief: The cable assembly features robust molded connectors that provide excellent strain relief. This design prevents conductor fatigue and loose connections caused by cabinet vibration or routine maintenance movements.

• Optimized Signal Integrity for Temperature Loops: Specifically rated for RTD and Thermocouple applications, the internal wire gauge and material properties minimize resistance errors, ensuring the PLC receives high-precision temperature data without signal degradation over the 2.5-meter run.

FAQs

• Does this cable support 1756-IF16 or 1756-IR6I modules?

  Yes. The 1492-ACABLE025UB belongs to the Bulletin 1492 wiring system specifically designed for the 1756 ControlLogix analog family, including high-density current/voltage, RTD, and thermocouple modules.

• Is this a 100% brand new Allen Bradley original part?

  Absolutely. We guarantee that every 1492-ACABLE025UB we ship is brand new and original in factory-sealed Allen Bradley packaging. We do not sell used, pulled, or third-party compatible cables.

• What is the benefit of the 2.5-meter length over shorter versions?

  The 2.5-meter length provides the necessary slack to route cables cleanly through wire ducts from upper PLC racks to lower terminal strips in standard 2000mm or 2200mm industrial enclosures, ensuring a professional and organized cabinet layout.

• Can I use this cable for digital 24V DC I/O?

  While physically possible, this cable is optimized for analog signal integrity. For digital I/O, we recommend using the standard 1492-CABLE series designed for higher current switching to ensure optimal performance across your control system.
