GE Mark VI Turbine Control System IS200WROBH1AAA Printed Circuit Board (PCB)

The technical specifications for the IS200WROBH1A board:

• Functional Acronym/Abbreviation: WROB
• Fuse Value: 3.15 A
• Redundancy Mode: Simplex, Redundant, or TMR (Triple-Modular Redundant)
• Relay: TRLY
• Terminal Board Compatibility (In TMR): TDBTH2, TDBTH4, TDBTH6
• Weight: 0.2 kg

The IS200WROBH1A is a Power Distribution Board from the Mark VI series, part of GE's Speedtronic line. It offers scalable redundancy levels for enhanced reliability and fault tolerance.

• Redundancy Levels:

  • Single (basic) controller with simplex I/O and a single network.
  • Dual system with two controllers, single or fanned TMR I/O, and dual networks for improved dependability and online repairs.
  • Triple-Modular Redundant (TMR) system with three controllers, solitary or fanned TMR I/O, three networks, and state voting among controllers for maximum fault detection and availability.

• Mounting and Compatibility:

  • Mounts on the TDBT board in TMR applications, providing terminal board functionality along with a contact input terminal board (TBCI).
  • Provides a similar potential to the IS20TRLYH1B board when connected to the TDBS board's relay part.

• Power Management:

  • Core distribution system and branch circuit elements are separate types responsible for primary power management in a cabinet or series of cabinets.

• Technical Details:

  • The card features twelve fuses, each rated for 500VAC/400VDC with a 3.15 A rating.
