Description
ICS Triplex TC‑201‑01‑4M5
Technical Specifications Finished length: 4.5 m; rated voltage: 300 V; operating temperature range: ‑40 °C ~ +70 °C; triplicated‑bus differential twisted‑pair conductors; integral copper‑braided shielding; metal‑shell locking‑type connectors; intended exclusively for cabinet‑internal static routing.
Functional Features Original‑factory pre‑crimped connectors with fixed pin mapping; multi‑group differential twisted‑pairs suppress high‑speed‑bus crosstalk; reinforced strain‑relief structure improves anti‑vibration performance; mechanical locking latches prevent vibration‑caused loosening; full‑shielding design rejects cabinet‑internal electromagnetic interference; standardized wire‑color marking supports maintenance inspection.
Application Scenarios Hot‑link interconnection between Trusted main controller chassis and T8300 expander chassis; multi‑expander‑chassis cascading for large‑point‑count SIS systems; ESD emergency‑shutdown‑system inter‑chassis communication wiring; petrochemical plant safety‑instrument‑system cabinet assembly.
Performance Parameters Shield coverage ratio greater than 85 %; gold‑plated‑pin contact resistance below 9 mΩ; insulation resistance above 1000 MΩ; connector mating life 500 cycles; signal transmission latency less than 1 ms; meets SIL 3 safety‑system‑cabling standards.
Material Composition Tinned stranded copper conductors, cross‑linked polyethylene insulation, copper‑braided shielding mesh, abrasion‑resistant PUR outer jacket, zinc‑alloy die‑cast metal connector housings, gold‑plated signal pins, injection‑molded rubber strain‑relief components.
Structural Characteristics Heavy‑duty rectangular metal‑shell connectors fitted at both cable ends; triplicated‑bus signal groups implemented with independent twisted‑pairs; injection‑molded strain‑relief treatment at cable‑connector transition sections; pin‑out strictly matches Trusted hot‑link‑bus hardware definitions.
Working Principle Transmits triplicated high‑speed Inter‑Module‑Bus signals between main‑chassis and expander‑chassis interface adapters. Twisted‑pair‑differential‑signal technology offsets electromagnetic‑induction noise. Continuous shielding diverts external interference to cabinet protective‑ground bar. Factory‑fixed pin‑assignment eliminates field‑wiring‑caused bus‑signal faults.
Installation Requirements Only for static installation inside temperature‑controlled control cabinets; static minimum bending radius equals ten times cable outer diameter; maintain slack reserve without tensile stress on cable; fasten mechanical locking latches after connector insertion; cable‑shield layer single‑end connects to cabinet protective‑ground bar; keep sufficient physical separation from high‑power power‑cable bundles.
Usage Notes Never pull cables by connector housings during handling; prevent cabinet sharp metal edges from damaging outer jacket; verify full‑model matching before connector insertion; forbid cutting or re‑processing factory‑terminated connectors; inspect pins for bending or deformation before power‑on; avoid cabinet‑internal zones with oil mist and corrosive‑gas accumulation.
