IS200TSVOH1BBB GE Mark VI Servo Terminal Board – TMR & Simplex

IS200TSVOH1BBB Servo I/O Terminal Board – GE Mark VI

IS200TSVOH1BBB is a servo terminal board from General Electric. It belongs to the Mark VI Speedtronic series. The board interfaces with electro-hydraulic servo valves for steam and fuel valve actuation. It supports both Simplex and TMR (Triple Modular Redundancy) signals. This design ensures fault tolerance and high system reliability.

The TSVO board provides continuous current monitoring and feedback validation. It integrates external trip inputs via JD1/JD2 connectors. The board uses surface-mount technology and operates in harsh industrial environments.
