Product Overview

The Emerson Ovation 5A26141G06 serves as a specialized factory-terminated communication link within the Ovation™ Distributed Control System. This 4.5-foot (1.37 m) coaxial cable facilitates high-speed data exchange between local I/O modules and the main controller. Specifically tuned for the 50 kHz carrier signal of the Ovation local bus, this 100% brand-new cable ensures transparent data flow in high-EMI environments like turbine decks and boiler rooms.

Engineering Advantages

Impedance-Matched Signal Integrity: The 75 Ω coaxial architecture prevents signal reflections that typically plague standard serial cables. This specific impedance ensures that the 50 kHz carrier frequency travels without attenuation or data corruption.
Superior Noise Immunity: The combination of braid and foil shielding provides 100% coverage against RFI and EMI. This protects the local I/O bus from the massive electromagnetic fields generated by large motors and switchgear in power generation facilities.
Optimized Propagation Delay: Emerson specifies the 4.5-foot length to match the timing requirements of the Ovation local bus. Using the factory-correct length prevents "ghost" signals and communication timeouts that often occur with unauthorized third-party cable lengths.
Robust Mechanical Locking: Standard DB9 screws secure the cable against high-vibration industrial environments. This mechanical lock prevents intermittent contact failures that could otherwise trigger false system trips or I/O communication loss.

FAQs

Can I use a standard DB9 serial cable instead of the 5A26141G06?

No. Standard serial cables lack the 75 Ω coaxial core required for the Ovation 50 kHz carrier signal. Using a non-coaxial cable will cause signal reflections, resulting in intermittent I/O communication errors or complete bus failure.
Why is the length fixed at 4.5 feet?

Emerson engineers the Ovation local bus around specific timing and capacitance parameters. The 4.5-foot length (G06) ensures the signal reaches its destination within the required microsecond window without reflecting back and interfering with subsequent data packets.
What are the best practices for grounding this cable?

Ground the cable shield at the controller side only. This "single-point" grounding strategy prevents circulating currents (ground loops) from interfering with the low-voltage communication signals between the controller and the I/O rack.
How does this cable handle oil or chemical exposure?

The 5A26141G06 features an industrial-grade PVC jacket. This material resists oil mist and common chemical vapors found in petrochemical and water treatment plants, preventing the jacket from cracking or becoming brittle over time.
