GE IS200TTURH1BCC Turbine Terminal / Protection Input Board

FAQ

Q1. What is the IS200TTURH1BCC board?
It’s a turbine terminal and protection input board for GE Mark VI Speedtronic control systems used to process speed pickups, voltage and shaft signals and interface protection logic.

Q2. What types of inputs does this board accept?
It accepts 12 passive turbine speed pulse inputs and voltage signals from potential transformers for generator and bus monitoring.

Q3. What output does the board provide?
It provides a 125 V DC output to control the main breaker coil when protection relays are actuated.

Q4. How do the relays on the board function?
Relays K25, K25P, and K25A must all close to enable 125 V DC breaker coil power, coordinating protection logic.

Q5. Where is this board installed?
The board mounts inside the turbine control rack or cabinet and interfaces with the turbine I/O processor/backplane.

Q6. Is this board specific to a particular GE control series?
Yes — it is designed specifically for GE Mark VI Speedtronic turbine control systems.

Q7. What are the physical size and weight of this board?
It measures about 16 cm × 16 cm × 12 cm and weighs around 0.8 kg.

Q8. What happens if this board fails?
A failure can disrupt speed and voltage sensing and may prevent proper breaker control and protection logic from functioning within the turbine control system.
