FAQ

Q1. What is the IS200ATBAG1BAA1 board used for?
It serves as a terminal/interface board that links the control system backplane signals to external field wiring in the GE Mark VI turbine control system, allowing sensor and actuator connections.

Q2. Which control system does it support?
It is designed specifically for use in the GE Mark VI Speedtronic turbine control architecture.

Q3. How does this board connect to the control system?
It connects to the Control Assembly Backplane (CABP) through two male vertical pin connectors labeled J6 (36‑pin) and J7 (25‑pin).

Q4. What types of signals can be wired through it?
It routes various analog and discrete signals such as digital status inputs, analog measurements, tachometer inputs, SSR outputs, and fault strings.

Q5. Does this board have a terminal block?
Yes, it includes a 60‑position terminal block for external wiring termination.

Q6. Does the board come with multiple revisions?
Yes, there are at least three documented revisions of this board, though not all may be backward compatible.

Q7. Can it be used outside of GE Mark VI systems?
No, its design and pinouts are specific to the Mark VI control backplane and are not generally compatible with other platforms.

Q8. How should it be handled during installation?
Because it interfaces with sensitive backplane and field signals, static precautions and correct ribbon/connector orientation must be used when installing or servicing.
