Technical Specifications Multi‑core shielded bus cable assembly. Operating temperature ‑20 ℃ to +70 ℃, storage temperature ‑40 ℃ to +85 ℃. Flame‑retardant outer sheath. Equipped with dedicated molded bus connectors on two ends. Multiple optional standard length versions.
Functional Features Transmits high‑speed system bus data between ABB control hardware units. Integrated shielding structure improves anti‑interference performance. Pre‑assembled connectors lower on‑site wiring workload and wiring fault risk. Supports quick replacement during maintenance work.
Application Scenarios Applied for internal bus connection of DCS and distributed I/O system. Used for cabinet assembly, field modification and spare‑part replacement.
Performance Parameters Maintains stable high‑speed bus signal transmission. Shielding structure suppresses cabinet electromagnetic noise. Connector contact keeps stable under mechanical vibration.
Material Composition Tinned copper multi‑core conductors. Polyethylene insulation. Copper‑braided overall shielding layer. Flame‑retardant outer sheath. High‑strength molded plastic plug‑in connectors.
Structural Characteristics Flexible finished cable assembly. Two‑end equipped with dedicated bus connectors matched with ABB hardware interfaces. Weight varies according to selected cable length.
Working Principle System bus differential data signal transmits through internal conductor pairs. Outer shielding layer isolates external electromagnetic interference. Dedicated connectors ensure correct pin‑to‑pin signal mapping between connected hardware units.
Installation Requirements Lay cable inside cabinet, keep separation distance from high‑voltage power cables. Fully insert two‑end connectors into corresponding bus interfaces. Fix cable with cable ties to avoid pulling stress on connectors. Connect shielding ground to cabinet protective grounding bar.
Usage Notes Prohibit sharp bending, scratching and stretching of cable. Do not disassemble molded connectors. Check connector insertion status during equipment overhaul. Replace cable immediately if sheath damage occurs.
