Advantages & Key Features

  • Absolute Maximum Channel Density: 48 isolated relay outputs in a single VME slot—the absolute highest channel density in the Mark VIe relay output terminal family, providing 50% more channels than IS200TRLYH1D (32 channels), double that of IS200TRLYH1C (24 channels), and triple that of IS200TRLYH1B (16 channels). Ideal for the largest turbine systems with extensive actuator control requirements.

  • High Contact Rating: 8A per channel with 15A inrush capability enables direct control of large solenoids, contactors, and valve actuators.

  • Extended Temperature Range: –40°C to +70°C operation makes IS200TRLYH1FAA suitable for extreme environments.

  • Enhanced Isolation: 2000 VAC isolation provides superior protection for the Mark VIe backplane.

  • Enhanced Suppression: Integrated flyback diodes, RC snubbers, and MOVs protect relay contacts and driver circuits.

  • Fast Response: < 8 ms energize and < 4 ms de-energize times ensure precise control.

  • Comprehensive Diagnostics: Coil open/short, welded contact, wear monitoring, and reference validation.

  • Ultra-High-Density Status Indication: 48 green/red LEDs enable rapid on-site troubleshooting.

  • ToolboxST Integration: Full configuration, monitoring, and diagnostics via GE ToolboxST.

  • Drop-In Replacement: Direct replacement for IS200TRLYH1F, IS200TRLYH1D, IS200TRLYH1C, and earlier relay output terminal boards.

Application Fields

  • Gas & Steam Turbines (GE Frame 6B/7EA/9E/HA): Fuel gas shut-off valves, emergency stop solenoids, alarm annunciators, lube oil pump starters, generator breaker trip coils, cooling fan starters, auxiliary system actuators, and comprehensive actuator control for the largest turbine systems.

  • Combined Cycle Plants: Steam turbine extraction valves, bypass actuators, HRSG damper controls, condensate pump starters.

  • Compressor Stations: Anti-surge valve solenoids, discharge blow-down valves, station shutdown relays.

  • Arctic & Desert Installations: Extreme-environment actuator control.

  • Nuclear Power Plants: Critical actuator control requiring documented diagnostics and reference validation.

Key Advantage: IS200TRLYH1FAA delivers 48 isolated relay outputs—the absolute highest channel density in the Mark VIe relay output terminal family—with 8A contact rating, 15A inrush capability, 2000 VAC isolation, extended –40°C to +70°C temperature range, and comprehensive diagnostics including reference validation—making it the ultimate solution for the largest turbine systems requiring maximum-density, high-current actuator control in extreme environments.

Selection Guidelines & Recommendations

  • Channel Count: 48 relay outputs per board—the absolute highest available.

  • Contact Rating: Confirm load requirements do not exceed 8A @ 250 VAC or 8A @ 30 VDC. For inductive loads, de-rate to 5A.

  • Inrush Capability: 15A for 50 ms—verify load inrush does not exceed this.

  • Load Protection: For highly inductive DC loads, add external varistors.

  • Diagnostic Configuration: Enable welded contact, wear monitoring, and reference validation for critical safety circuits.

  • Controller Firmware: Requires Mark VIe processor firmware v9.5 or later.

  • Spare Strategy: Keep one spare per turbine; lead times 8–14 weeks.

  • Retrofit: Direct replacement for IS200TRLYH1F, IS200TRLYH1D, IS200TRLYH1C, and IS200TRLYH1B—regenerate configuration in GE ToolboxST for 48-channel mapping.

Important Cautions

  1. No Hot-Swap: De-energize rack before insertion/removal.

  2. Wiring Polarity: For DC loads, observe correct polarity—reverse polarity shorts through the flyback diode.

  3. Contact Protection: For loads exceeding 8A, use external contactors.

  4. Grounding: Connect chassis ground at single star point.

  5. Shield Termination: Ground output cable shields only at cabinet end.

  6. ESD Handling: Use grounded wrist straps; field repair not possible.

  7. Temperature Rating: Verify cabinet ambient does not exceed +70°C or fall below –40°C.

  8. Reference Validation: Yellow LED indicates reference drift—schedule factory recalibration if illuminated.

  9. Welded Contact Detection: Refer to GE wiring diagram IS200TRLYH1FAA-DWG.

  10. Wear Monitoring: Set operational thresholds in GE ToolboxST for maintenance alerts.

  11. Power Supply: Ensure adequate current for all active outputs (40 mA × 48 = 1.92 A max).

  12. Channel Mapping: With 48 channels, verify field wiring maps to correct ToolboxST channel numbers.

  13. Wiring Density: With 48 relay outputs, ensure adequate cabinet space and cable management to maintain proper airflow.
