Emerson Ovation 5A26159G18 Signal Interconnect Cable Assembly
5A26159G18 is an original factory-terminated dedicated interconnection cable assembly for Emerson Ovation DCS distributed control systems. The suffix G18 stands for a validated, locked hardware revision, which has passed full factory outgoing inspections including continuity test, dielectric withstand test, shielding efficiency test and pinout one-to-one matching verification.
This cable acts as a dedicated physical signal transmission medium linking Ovation I/O modules, rack backplanes and cabinet signal transfer panels. It reliably transmits analog process sampling signals, digital equipment status feedback signals and safety interlock control signals. Equipped with dual-end gold-plated lockable precision connectors and complete multi-layer EMI/RFI shielding structure, it effectively suppresses electromagnetic interference inside control cabinets and avoids analog signal drift, accidental digital signal triggering and communication jitter. It is widely used for new cabinet assembly, on-site unit retrofitting and spare parts stocking in thermal power, petrochemical and other process industries.
Description
Product Description
This fixed-length factory cable uses industrial shielded wire, with precision crimped mating locking connectors fitted on both ends. One connector plugs into the dedicated signal port of Ovation I/O cards or rack backplane interfaces, while the other connects to cabinet terminal blocks or transition panels, establishing point-to-point hard wiring between the control layer and field wiring terminals.
Every finished cable undergoes strict final quality inspection to eliminate open circuits, short circuits, reversed pin assignment and insufficient crimping defects, fully adapting to 24/7 continuous operation and long-term vibration working conditions of industrial control cabinets.
Core Performance Features
1. Point-to-Point Accurate Signal Transmission
Custom-designed for internal analog and digital signal loops inside Ovation cabinets. Strict one-to-one pin mapping eliminates crosstalk and misconnection risks, ensuring accurate collection of field process parameters and reliable delivery of safety interlock control instructions.
2. Dual-Layer Anti-Interference Shielding Structure
Adopts overall braided copper mesh shielding plus independent individual core shielding. It isolates EMI and RFI noise generated by cabinet contactors, variable frequency drives and cooling fans, greatly reducing measurement deviation and accidental switching actions induced by external interference.
3. Gold-Plated Locking Anti-Loose Connectors
Both ends are equipped with industrial gold-plated connectors with built-in snap locking latches. Gold-plated contacts lower contact resistance and resist oxidation and corrosion in humid cabinet environments; the locking mechanism prevents poor contact caused by long-term equipment vibration and guarantees consistent long-term connection reliability.
4. Flame-Retardant, Oil-Resistant and Anti-Aging Outer Jacket
The cable outer sheath is made of high-tensile flexible flame-retardant insulation material, resistant to oil mist, dust and cyclic temperature changes inside power plant cabinets. It delivers superior bending fatigue resistance, suitable for fixed routing and limited bending layout, with no insulation cracking or conductor breakage after repeated plugging and long-term vibration.
5. Plug-and-Play Native System Compatibility
No adapters, on-site wiring modification or secondary crimping is required. It directly mates with standard interfaces of full-series Ovation I/O modules, rack backplanes and transition panels, perfectly matching the Ovation DCS platform and simplifying on-site installation, troubleshooting and spare part replacement.
6. Tagged Fixed-Length Finished Cable
Supplied pre-assembled with unified cable ID tags and pin number labels, facilitating cable sorting, identification and subsequent circuit maintenance inside cabinets, and significantly shortening on-site wiring and commissioning cycles.
