Product Overview

The Emerson Ovation 5A26137G03 functions as a high-performance, factory-terminated cable assembly specifically engineered for the Ovation™ Distributed Control System (DCS). This module-to-module interconnect facilitates both low-voltage power distribution and critical signal transmission between controllers and I/O modules. By utilizing a high-density shielded design, this 100% brand-new cable maintains signal purity in electrically noisy environments. It serves as a vital component in power generation and chemical processing facilities where data loss or power fluctuations cannot occur.

Technical Specifications

The 5A26137G03 utilizes industrial-grade materials to ensure long-term stability under continuous thermal and mechanical stress.

Engineering Advantages

• Superior Noise Rejection: The aluminum foil shield, combined with a dedicated drain wire, provides a comprehensive barrier against Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). This allows the cable to carry sensitive signals alongside power lines without data corruption.

• Optimized Power Delivery: The 18 AWG high-purity copper conductors minimize voltage drop across the cable length. This ensures that remote I/O modules receive the precise voltage required for accurate analog-to-digital conversion and logic processing.

• Industrial Durability: The flame-retardant PVC jacket resists oils, chemicals, and mechanical abrasion. This robust construction prevents jacket failure in the harsh environments of petrochemical refineries and power plant turbine decks.

• Plug-and-Play Integration: Factory-terminated connectors eliminate the need for field crimping, which often introduces high-resistance points. This ensures a low-impedance connection that matches the native electrical characteristics of the Ovation DCS backplane.

FAQs

• Can the 5A26137G03 carry 120VAC power?

  No. This cable is rated for 300V but is specifically designed for low-voltage signal and DC power distribution (typically 24VDC) within the Ovation rack. Using it for high-voltage AC mains may exceed the thermal limits of the insulation and jacket.

• What is the significance of the UL VW-1 and CSA FT4 flame ratings?

  These ratings certify that the cable jacket self-extinguishes within a specified time frame during a fire. This prevents the cable from spreading flames between control cabinets, meeting the strict safety requirements for nuclear and thermal power plants.

• Should I ground the shield at both ends?

  No. To prevent circulating currents or "ground loops" that introduce noise into your control signals, ground the shield at the designated end only (usually the controller or power supply side) as per Emerson installation standards.

• How does this cable handle tight cabinet bends?

  While the cable is flexible enough for panel wiring, you must maintain the minimum bend radius (typically 6 to 10 times the cable diameter) to avoid stressing the copper conductors and compromising the shielding effectiveness.
