  • The ‘A’ revision brings improved LED brightness and contact material
  • Specialized variant designed for specific customer requirements or non-standard annunciation schemes
Working Principle:​ The board handles annunciator relay outputs with visual status LEDs, but in a non-standard layout designed for specific customer applications or non-standard channel configurations.
Application Scenarios:​ Special/custom annunciation schemes in Mark VIe Speedtronic turbine control systems.
Compatible Replacement Models:
  • Drop-in Replacement:​ IS200TRPAS1 — The base revision. Identical pinout, mounting, and software interface
  • Software Compatible:​ IS200TRPAH1A — Standard annunciator board. Different channel configuration and pinout—may not be a direct match
  • Software Compatible:​ IS200TREGH1A — Standard relay output board without annunciator-specific features
  • Hardware Incompatible:​ IS200TPROH1A — Triac output board with different application and switching characteristics
Important Notes:
  • If you’re replacing an existing ‘S1A’ board, match the suffix
  • If you’re substituting a standard TRPA board, verify compatibility—the pinout and channel mapping may differ significantly
  • The ‘S1’ indicates a specialized or custom configuration—not a standard density variant
  • The pinout and channel mapping may differ from standard TRPA boards
