Emerson Ovation 5A26155G48 Signal Interconnect Cable Assembly
5A26155G48 is an original factory prefabricated signal interconnection cable assembly dedicated to the Emerson Ovation DCS system. The suffix G48 refers to a customized and finalized hardware revision, which has passed a full set of factory quality inspections including continuity test, dielectric withstand test, shielding efficiency verification and pinout consistency check.
This cable establishes physical connection links among Ovation I/O modules, rack backplanes and cabinet signal transfer panels. It stably transmits analog acquisition signals, digital equipment status feedback signals and safety interlock control signals. Equipped with gold-plated locking precision connectors on both ends and a complete double-layer EMI/RFI shielding structure, it effectively restrains electromagnetic interference inside cabinets and eliminates common faults such as analog signal drift, accidental digital signal triggering and communication jitter. It is widely deployed for complete cabinet assembly, unit expansion & renovation, and spare part replacement in thermal power plants, petrochemical plants and other related industries.
Description
1. Product Description
This pre-terminated cable adopts industrial-grade shielded wire with fixed factory length, with matched locking connectors crimped precisely at both terminals. One connector plugs into the dedicated signal port of Ovation I/O cards or rack backplanes, and the other connects to cabinet terminal blocks or transfer panels, realizing point-to-point hard wiring connection between the control layer and field wiring terminals.
Each finished cable undergoes full outgoing inspection to rule out open circuits, short circuits, reversed pin assignments and poor crimping defects, perfectly fitting the 7×24-hour non-stop continuous operation and long-term vibration working conditions of industrial control cabinets.
2. Core Functional Features
2.1 Accurate Point-to-Point Signal Transmission
Designed exclusively for analog and digital signal loops inside Ovation cabinets. Strict one-to-one pin definition avoids crosstalk between wires and misconnection risks, ensuring precise collection of field process parameters and reliable delivery of interlock control commands.
2.2 Double-Layer Composite Anti-Interference Shielding Structure
It adopts a combined structure of overall braided copper mesh overall shielding plus independent separate shielding for each inner core wire. It isolates electromagnetic interference and radio frequency interference generated by cabinet contactors, frequency converters and cooling fans, greatly reducing measurement deviation and false switching actions induced by external noise.
2.3 Gold-Plated Locking Anti-Loose Precision Connectors
Gold-plated contacts lower contact resistance and resist oxidation and corrosion in humid cabinet environments. The integrated snap locking structure prevents poor contact caused by long-term equipment vibration and guarantees consistent long-term connection reliability.
2.4 Flame-Retardant, Oil-Resistant and Anti-Aging Outer Jacket
The 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 outstanding bending fatigue resistance, suitable for fixed routing and limited bending layout, with no insulation cracking or core wire fracture after repeated plugging and prolonged vibration.
2.5 Native Plug-and-Play Compatibility with the System
No adapters, on-site wiring modifications or secondary crimping are 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, troubleshooting and spare part replacement.
2.6 Standard Tagged Fixed-Length Finished Cable
Supplied as pre-assembled fixed-length cable with unified cable ID tags and pin number labels, facilitating cable sorting, identification and subsequent circuit maintenance inside cabinets, and significantly shortening on-site engineering wiring and commissioning cycles.
