Emerson Ovation 5A26141G12 Interconnect Cable Assembly
5A26141G12 is an original factory-terminated dedicated interconnection cable assembly for Emerson Ovation DCS. The suffix G12 represents a fixed hardware revision that has passed continuity testing, dielectric withstand testing, shielding performance testing and pinout verification at the factory. It serves as a dedicated physical transmission path linking Ovation DPU controllers, I/O racks and signal transfer panels, reliably carrying system internal bus signals and digital control signals. Fitted with dual-end gold-plated precision locking connectors and full EMI/RFI shielding structure, it effectively suppresses cabinet internal electromagnetic interference and delivers long-term stable signal transmission. It is widely used for new cabinet assembly, remote I/O expansion and spare part replacement during unit retrofits in thermal power, petrochemical and other process industries.
Description
1. Product Description
This pre-assembled cable adopts industrial shielded cable with factory-set fixed length, with precision crimped mating connectors on both ends. One connector plugs into the communication port of Ovation DPUs or rack backplanes, and the other connects to cabinet signal transfer panels, implementing point-to-point hard wiring interconnection between control layer and field wiring layer. Every finished cable undergoes strict outgoing inspection to eliminate open circuits, short circuits and miswiring, fully adapting to 24/7 continuous operation conditions of industrial control cabinets.
2. Core Features
2.1 Point-to-Point Accurate Signal Transmission
Specially used for transmitting internal system bus communication signals and digital control signals between Ovation DPUs and transfer panels. Strict one-to-one pin assignment avoids crosstalk and misconnection risks, ensuring real-time accurate data interaction between main controllers and field signal terminals.
2.2 Double-Layer Full Shielding Anti-Interference Design
It adopts overall braided shielding plus individual core shielding structure, which effectively resists EMI and RFI interference generated by cabinet contactors, variable frequency drives and cooling fans. Signal integrity is greatly improved to prevent communication signal distortion, jitter or loss.
2.3 Gold-Plated Lockable Precision Connectors
Both ends are equipped with industrial gold-plated connectors with built-in anti-loosening latches, preventing poor contact caused by long-term cabinet vibration. Gold-plated pins reduce contact resistance and maintain stable electrical performance throughout the service life.
2.4 Flame Retardant and Wear Resistant Outer Jacket
The cable sheath is made of high-tensile, oil-resistant, flame-retardant flexible material, suitable for fixed wiring and limited bending layout inside control cabinets. It withstands repeated plugging and long-term vibration without core breakage or insulation damage.
2.5 Native Plug-and-Play Compatibility
No adapters or on-site wiring modification required. It directly mates with standard communication interfaces of Ovation DPUs, rack backplanes and transfer panels, compatible with full-series Ovation I/O modules and standard control cabinets, simplifying field construction, troubleshooting and spare parts replacement.
2.6 Standard Labeled Fixed-Length Finished Cable
Delivered as prefabricated fixed-length cable with unified tags and pin labels, facilitating internal cabinet cable sorting, identification and subsequent circuit inspection, greatly shortening on-site engineering wiring cycle.
