Emerson Ovation 5A26161G12 Signal Interconnect Cable Assembly
5A26161G12 is an original factory pre-terminated dedicated interconnection cable assembly designed for Emerson Ovation DCS distributed control systems. The suffix G12 stands for a verified and fixed hardware revision, which has passed a complete set of factory outgoing tests including continuity detection, dielectric withstand test, shielding efficiency inspection and pinout consistency verification.
This cable serves as a dedicated physical signal transmission link connecting Ovation I/O modules, rack backplanes and cabinet signal transfer panels. It stably transmits analog process sampling signals, digital equipment status feedback signals and safety interlock control signals. Equipped with gold-plated lockable precision connectors at both ends and a full multi-layer EMI/RFI shielding structure, it effectively suppresses electromagnetic interference inside control cabinets and avoids problems such as analog signal drift, false triggering of digital signals and communication jitter. It is widely applied to new cabinet assembly, on-site unit renovation and spare parts stocking in thermal power, petrochemical and other process industries.
Description
Detailed Product Description
This prefabricated cable assembly adopts industrial-grade shielded cable with a fixed length set at the factory, with precisely crimped matched locking connectors installed at both terminals. One connector plugs into the dedicated signal interface of Ovation I/O modules or rack backplane ports, while the other connects to cabinet terminal blocks or signal transfer panels, achieving point-to-point hard wiring connection between the control layer and field wiring terminals.
Each finished cable undergoes strict outgoing quality inspection to eliminate defects including open circuits, short circuits, miswiring and insufficient crimping, fully adapting to the 24/7 non-stop continuous operation and long-term vibration working conditions of industrial control cabinets.
Core Functional Features
1. Point-to-Point Accurate Signal Transmission
Customized for analog and digital signal loops inside Ovation control cabinets. Strict one-to-one pin mapping eliminates risks of signal crosstalk and misconnection, ensuring accurate collection of field process parameters and reliable issuance of safety interlock control commands.
2. Dual-Layer Integrated Anti-Interference Shielding Structure
It adopts a composite structure of overall braided copper mesh shielding plus independent shielding for each single core wire. The structure isolates EMI and RFI interference generated by cabinet contactors, variable frequency drives and cooling fans, greatly reducing analog measurement deviation and accidental digital signal triggering caused by external noise.
3. Gold-Plated Anti-Loose Lockable Precision Connectors
Both ends are fitted with industrial gold-plated connectors integrated with snap locking latches. Gold-plated pins reduce contact resistance and resist oxidation and corrosion in humid cabinet environments. The locking structure prevents poor contact resulting from long-term equipment vibration and delivers long-term stable connection reliability.
4. Flame-Retardant, Oil-Resistant & Anti-Aging Outer Jacket
The outer sheath is made of high-tensile flexible flame-retardant insulating material, resistant to oil mist, dust and cyclic temperature fluctuations inside power plant cabinets. It features excellent bending fatigue resistance and fits fixed routing and limited bending layout; no insulation cracking or core wire breakage occurs after repeated plugging and long-term vibration.
5. Native Plug-and-Play System Compatibility
No adapters, on-site wiring modification or secondary crimping work is required. It directly mates with standard interfaces of full-series Ovation I/O modules, rack backplanes and transfer panels, perfectly matching the Ovation distributed control platform and simplifying on-site installation, fault troubleshooting and spare part replacement work.
6. Standard Tagged Fixed-Length Prefabricated Cable
Supplied as pre-assembled fixed-length finished cable with unified cable ID tags and pin number labels, facilitating cable sorting, identification and subsequent circuit maintenance inside cabinets, and significantly shortening the on-site engineering wiring and commissioning cycle.
