ICS Triplex TC-303

ICS Triplex TC-303

Product Introduction: The TC-303 is a triple modular redundant remote expansion cable specifically engineered for the ICS Triplex Trusted T8000 safety instrumented system. This cable establishes the critical electrical backend link within a Trusted remote expansion pathway, connecting the T8314 Fiber Optic Transceiver to the T8310 Expander Processor. It enables high-speed, fault-tolerant communication alongside power distribution between remote I/O expansion chassis and the main controller cabinet.

Functional Features:

  • Triple-channel communication redundancy ensures continuous operation during single-point failures
  • Individual pair shielding combined with overall shielding provides exceptional electromagnetic and radio frequency interference immunity
  • Keyed connectors prevent mis-wiring during installation
  • Hot-swap compatible design allows replacement without system shutdown
  • Flame retardant properties meeting IEC 60332-1 standards

Application Scenarios:

  • Safety instrumented systems in oil and gas production facilities
  • Chemical processing plants requiring remote I/O expansion
  • Power generation stations with distributed control architectures
  • Pharmaceutical manufacturing with extended I/O requirements

Performance Parameters:

  • Operating temperature range from -40°C to +70°C
  • Storage temperature range from -40°C to +85°C
  • Humidity tolerance from 5% to 95% relative humidity non-condensing
  • Pollution degree PD2 classification

Material Composition:

  • PVC outer jacket for general-purpose indoor applications
  • Tinned copper conductors for corrosion resistance
  • Aluminum foil and copper braid shielding layers

Structural Characteristics:

  • 96-pin Type C connector at T8310 end with double-wide hood
  • Three 4-core LEMO-style plugs at T8314 end
  • Black PVC outer jacket for cabinet and raceway installations

Working Principle: The cable transmits three independent differential communication channels simultaneously while carrying 24 VDC power. The TMR architecture ensures that even if one communication channel experiences a fault, the remaining two channels maintain data integrity through majority voting.

Installation Requirements:

  • Minimum bend radius of 120 mm must be observed
  • Suitable for cabinet interior and raceway routing
  • Proper connector alignment using keyed interfaces mandatory

Usage Precautions:

  • Avoid sharp bends that exceed minimum radius specifications
  • Ensure connectors are fully seated and locked
  • Verify polarity before energizing power conductors
  • Inspect shielding continuity during installation
