1. Product Description
This prefabricated cordset cable adopts industrial-grade multi-layer shielded communication cable with factory fixed customized length, fitted with precisely crimped matched locking connectors on both terminals. One connector plugs into the AUI communication interface of Ovation remote I/O modules, and the other connects to the main control rack backplane or controller communication port, realizing point-to-point dedicated hard wiring between remote I/O field stations and central control layer. Every finished cable undergoes strict outgoing quality inspection to eliminate open circuits, short circuits, miswiring and poor crimping faults, fully adapting to 24/7 non-stop continuous operation and long-term vibration environment of industrial control cabinets.
2. Core Functional Features
2.1 High-Speed AUI Bus Point-to-Point Signal Transmission
Specially customized for Ovation AUI remote I/O bus architecture, strictly one-to-one pin mapping ensures high-speed, low-latency transmission of I/O acquisition data, control commands and status feedback signals between remote stations and main controllers, no signal crosstalk or data packet loss occurs.
2.2 Dual-Layer Integrated Full Shielding Anti-Interference Structure
Adopts overall braided copper mesh shielding plus independent individual core wire shielding dual-layer design, effectively isolates EMI & RFI interference generated by cabinet contactors, variable frequency drives, cooling fans and high-power field equipment, greatly improves signal integrity and avoids communication jitter, frame error or link disconnection.
2.3 Gold-Plated Anti-Loose Lockable Precision Connectors
Both ends use industrial gold-plated connectors with built-in buckle locking mechanism; gold-plated pins reduce contact resistance and resist oxidation and corrosion in humid cabinet environment, the locking structure prevents loose contact caused by long-term equipment vibration, guaranteeing stable long-term connection reliability.
2.4 Flame-Retardant, Oil-Resistant & Anti-Aging Outer Jacket
The outer sheath is made of high-tensile flexible flame-retardant PVC material, resistant to oil mist, dust and temperature fluctuation inside power plant cabinets; excellent bending fatigue resistance, suitable for fixed routing and limited bending layout, no insulation cracking or core wire fracture after repeated plugging and long-term vibration.
2.5 Native Plug-and-Play System Compatibility
No adapters, wiring modification or on-site secondary crimping required; directly mates with standard AUI ports of full series Ovation remote I/O modules, rack backplanes and DPU controllers, perfectly compatible with Ovation distributed control platform, simplifies field wiring construction, troubleshooting and spare part replacement work.
2.6 Standard Labeled Fixed-Length Finished Cable
Delivered as pre-assembled finished cable with unified cable ID tags and pin number labels, convenient for internal cabinet cable sorting, identification and later circuit inspection and maintenance, significantly shortens on-site engineering wiring and debugging cycle.
