Functional Features

  1. 32 TMR Output Channels: Triple redundant signal paths with voting logic eliminate single-point failures for SIL 3 compliance.
  2. 120Vdc Field Device Control: Drives valves, pumps, and actuators with 1.0A continuous current per channel (2.0A peak).
  3. 2500Vrms Opto-Galvanic Isolation: Protects backplane from field-side transients and noise.
  4. Per-Channel Overcurrent Protection: Solid-state current limiting replaces fuses; auto-resets after fault clearance.
  5. Automatic Line Monitoring: Detects open circuits, short-to-bus, and short-to-ground; reports faults to controller in real time.
  6. Hot-Swap Capability: Enables module replacement without system shutdown, minimizing process disruption.
  7. SmartSlot Integration: Plug-and-play with T8100 chassis; auto-detected by Trusted Toolset for configuration.
  8. FTA Compatibility: Works with T8850C FTAs via TC-505 series cables for isolated field wiring.
  9. Continuous Self-Tests: Runs diagnostics on drivers, voters, and monitors; flags internal faults via front-panel LEDs and system alarms.
  10. UL 94 V-0 Flame Retardancy: Self-extinguishes quickly to reduce fire risk in control rooms.
  11. Front-Panel LED Indicators: Channel status (ON/OFF), module health, and fault alerts for quick troubleshooting.
  12. No Fuses Required: Solid-state overcurrent protection reduces maintenance and eliminates fuse replacement downtime.

Application Scenarios

  1. Oil & Gas Refinery ESD Valves: Controls 120Vdc emergency shutdown (ESD) valves via T8850C FTAs; uses TMR voting to prevent spurious trips and line monitoring to detect broken valve wiring.
  2. Chemical Plant Reactor Isolation: Drives 120Vdc isolation valves for batch reactor safety; hot-swap capability allows maintenance during non-critical phases without process shutdown.
  3. Power Generation Turbine Bypass Actuators: Controls 120Vdc bypass valves for turbine overspeed protection; 2500V isolation blocks generator-side transients from safety system backplane.
  4. Marine Offshore FPSO Fire & Gas (F&G) Actuation: Triggers 120Vdc fire suppression actuators and ventilation dampers; TMR logic ensures reliable response to gas detection alarms in harsh marine environments.
  5. Mining Hoist Brake Control: Operates 120Vdc hoist brake solenoids; per-channel overcurrent protection prevents damage from shorted coils while line monitoring detects broken wiring before critical failures.
  6. Pharmaceutical Batch Process Isolation: Controls 120Vdc drain valves for FDA-compliant batch systems; automatic fault reporting ensures validation-ready process data and minimal downtime.
