This cable builds a dedicated physical signal transmission link between 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 dual-end gold-plated lockable precision connectors and complete double-layer EMI/RFI shielding structure, it effectively suppresses electromagnetic interference inside control cabinets and eliminates common problems including analog signal drift, accidental digital signal triggering and communication jitter. It is widely used for complete cabinet assembly, on-site unit renovation and spare parts inventory supplement in thermal power, petrochemical and other continuous process industries.

This prefabricated cable assembly adopts industrial-grade shielded cable with factory preset fixed length, with precisely crimped matched locking connectors mounted on 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, realizing point-to-point hard wiring connection between the control layer and field wiring terminals.

Each finished cable undergoes strict outgoing quality inspection to rule out open circuits, short circuits, miswiring, insufficient crimping and other hidden defects, fully adapting to the 24/7 non-stop continuous operation and long-term vibration working conditions of industrial control cabinets.

Custom-designed for analog and digital signal loops inside Ovation control cabinets. Strict one-to-one pin mapping eliminates signal crosstalk and misconnection risks, ensuring accurate collection of field process parameters and reliable delivery of safety interlock control commands.

It adopts a composite structure of overall braided copper mesh shielding plus independent shielding for each individual core wire. This 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.

Both ends are fitted with industrial gold-plated connectors integrated with snap locking latches. Gold-plated pins lower contact resistance and resist oxidation and corrosion in humid cabinet environments. The locking structure prevents poor contact caused by long-term equipment vibration and ensures long-term stable connection reliability.

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 is suitable for fixed routing and limited bending layout; no insulation cracking or core wire breakage occurs after repeated plugging and long-term vibration.

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.

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.
