Description
Ics Triplex TC‑301‑02‑2M0
Technical Specifications Cable finished length 2.0 meters. Multi‑twisted‑pair internal signal conductors. Rated voltage 300V. Operating temperature ‑40°C to +70°C. Dual‑end metal‑shell industrial connectors. Full‑coverage copper braid shielding. Designed for static cabinet internal installation. Conforms to IEC 61508 safety‑system wiring specifications.
Functional Features Factory‑completed pin‑to‑pin termination removes manual wiring errors. Twisted‑pair layout optimizes differential signal anti‑interference performance. Reinforced strain‑relief prevents cable‑pin fatigue failure under cabinet vibration. Mechanical locking mechanism on connectors avoids loose connection. Standard wire color marking scheme for maintenance traceability. Shielding layer isolates high‑frequency noise from cabinet power components.
Application Scenarios SIS cabinet internal module‑FTA interconnection, emergency shutdown system signal link, burner safety control cabinet assembly, chemical‑plant safety instrumented cabinet wiring, turbine safety protection system cabinet wiring.
Performance Parameters Shield coverage rate ≥85%. Contact resistance per gold‑plated pin ≤9mΩ. Insulation resistance ≥1000MΩ. Signal crosstalk value stays within Trusted system allowable limits. Mechanical connector mating cycle rating reaches 500 insertion cycles.
Material Composition Tinned fine‑strand copper conductors, cross‑linked polyethylene insulation, copper braided shielding net, PUR wear‑resistant outer sheath, die‑cast zinc‑alloy metal connector housings, gold‑plated signal contact pins, injection‑molded strain‑relief rubber parts.
Structural Features Rectangular heavy‑duty metal shell connectors installed on both cable ends. Each differential signal adopts independent twisted‑pair grouping. Injection‑molded strain‑relief at cable‑connector transition area. Outer woven protective sleeve for cabinet routing section. Fixed pin mapping matches designated Trusted module and FTA combination.
Working Principle Transmits multi‑bit digital and analog safety signals between TMR I/O module and field termination unit. Twisted‑pair conductor layout offsets electromagnetic induction interference. Continuous shielding layer diverts external noise energy to cabinet protective earth ground. Fixed pin assignment guarantees correct signal routing without manual cross‑connection errors.
Installation Requirements Use exclusively inside climate‑controlled control cabinet. Keep minimum bending radius equal to 10 times cable outer diameter. Do not stretch cable under mechanical tension. Fully engage connector locking latches after plug‑in. Implement single‑end shielding grounding at cabinet ground bar. Maintain physical separation distance from high‑power AC wiring inside cabinet.
Usage Notes Do not apply pulling force directly onto connector shells during handling. Prevent sharp metal edges cutting outer sheath. Verify model compatibility before connecting to hardware ports. Do not cut, strip or re‑terminate factory‑built connectors. Visually inspect connector pins for bending or damage prior to system power‑on. Prevent contact with oil and corrosive chemical vapors.
