ICS Triplex T8310

Product Overview The T8310 is a specialized expander processor module developed for the ICS Triplex Trusted Triple Modular Redundancy system. It serves as the primary communication bridge between the main controller and additional expansion chassis, extending the Inter-Module Bus across multiple racks using Unshielded Twisted Pair cabling. This enables horizontal scaling of I/O capacity without compromising system speed or safety integrity.

Working Principle The T8310 inhabits the dedicated processor slot of an expansion chassis, managing data traffic between the main controller and expansion I/O modules. It extends the Inter-Module Bus across multiple racks using triplicated UTP cable links. The 3-2-0 voting logic processes data from three independent paths, isolating faults within the bus, chassis, or module to prevent system-wide failures. The dual ARM processors execute fault containment protocols ensuring localized failures do not propagate.

Installation Requirements

  • Install in processor slot of expansion chassis only
  • Connect to main controller via UTP expansion bus cables
  • Configure chassis ID using onboard switches, controller chassis set to ID 1, expander chassis from 2 to 8
  • Provide dual redundant 24 VDC power supplies
  • Ensure proper cable shielding and termination

Operating Precautions

  • Verify chassis ID configuration is unique within the system
  • Monitor Active and Standby LED indicators for proper operation
  • Do not remove module while actively processing safety-critical I/O without verifying redundancy status
  • Maintain UTP cable integrity, checking for damage or loose connections regularly
  • Replace faulted modules promptly to restore full TMR capability
