1. Product Introduction
This prefabricated cable assembly adopts industrial-grade shielded cable with factory fixed length, furnished with precisely crimped mating connectors at both terminals. One connector plugs into the communication port of Ovation DPU controllers or rack backplanes, while the other connects to cabinet signal transfer panels, realizing point-to-point hard wiring interconnection between the control layer and field wiring layer. Each finished cable undergoes strict outgoing quality checks to eliminate open circuits, short circuits and miswiring issues, fully adapting to the 24/7 non-stop operation conditions of industrial control cabinets.
2. Core Functional Features
2.1 Point-to-Point Precise Signal Transmission
It is specially engineered to transmit internal system bus communication signals and digital control signals between Ovation DPUs and transfer panels. Strict one-to-one pin mapping eliminates signal crosstalk and misconnection risks, ensuring real-time and accurate data interaction between master controllers and field signal terminals.
2.2 Dual-Layer Full Shielding Anti-Interference Design
It features a combined structure of overall braided shielding plus independent shielding for each core wire, which effectively resists EMI and RFI interference generated by cabinet contactors, variable frequency drives and cooling fans. Signal integrity is greatly enhanced to avoid distortion, jitter or loss of communication signals.
2.3 Gold-Plated Lockable Precision Connectors
Both ends adopt industrial gold-plated connectors with integrated anti-loose latches, preventing poor contact triggered by long-term cabinet vibration. Gold-plated pins lower contact resistance and maintain consistent electrical performance throughout the entire service life.
2.4 Flame-Retardant & Abrasion-Resistant Outer Jacket
The cable outer sheath is made of high-tensile, oil-resistant and flame-retardant flexible material, suitable for fixed routing and limited bending layout inside control cabinets. It withstands repeated plugging and long-term vibration without core wire fracture or insulation damage.
2.5 Native Plug-and-Play System Compatibility
No adapters or on-site wiring modifications are needed. It directly mates with standard communication interfaces of Ovation DPUs, rack backplanes and transfer panels, and is compatible with the full series of Ovation I/O modules and standard control cabinets, simplifying field construction, troubleshooting and spare part replacement work.
2.6 Standard Tagged Fixed-Length Finished Cable
Delivered as pre-assembled fixed-length cable with unified cable tags and pin labels, facilitating cable sorting, identification and subsequent circuit inspection inside cabinets, and significantly shortening the on-site engineering wiring cycle.
