Description
GE IS200RAPAG1BCA (often referenced under the RAPA series) is a specialized Rack Power Supply printed circuit board assembly engineered specifically for the General Electric Mark VI Speedtronic gas and steam turbine control systems. Designed to mount directly into an Innovation Series board rack, this module distributes regulated DC operating voltages to other cards within the rack via its P1 backplane connector.

Operating Guidelines and Usage Methods
Proper integration and handling of the rack power supply board require strict adherence to electronic safety and standard industrial handling protocols.
- ESD Precautions: Always utilize a certified grounded electrostatic discharge (ESD) wrist strap when handling the printed circuit board to safeguard sensitive internal microcircuits and onboard 1024-bit serial memory chips from static damage.
- Rack Placement: The RAPA board slides directly into designated slots within the Innovation Series rack, interfacing securely through its P1 backplane connector (featuring three rows of 32 pins).
- Environmental Control: Operate the host control cabinet within a clean, climate-controlled environment shielded from excessive humidity, airborne dust, and severe temperature fluctuations.
Power-On and Power-Off Sequence
Adhering to correct energization protocols prevents electrical transients and protects internal rack backplane components.
- Power-On Sequence:
- Confirm that the IS200RAPAG1BCA board is securely seated in its designated rack slot and backplane pins are fully engaged.
- Switch on the primary cabinet power distribution feeds supplying the Mark VI control racks.
- Monitor front-panel diagnostic LED indicators (IPOK and MPOK) to verify normal power distribution and operational status.
- Power-Off Sequence:
- Safely take the turbine control rack offline via the operator workstation software if required.
- Power down the main electrical feeds supplying the system control racks.
- Allow adequate time for internal filter capacitors and heat sinks to completely discharge and cool down before servicing or extracting the board.
Product Instructions
The RAPA board manages internal power conversion and supplies regulated voltage rails (such as +5 VDC, \pm15 VDC, and unregulated bulk lines) to companion control and communication cards in the rack. The front panel features a reset push button, two status LEDs, and four test points (N15, P5, P15, and DCOM) for live diagnostic measurement. Keep cabinet ventilation clear to maintain optimal thermal stability.
Frequently Asked Questions (Q&A)
- Q: What system utilizes the IS200RAPAG1BCA board?
- A: It is deployed as a core rack power supply within the GE Mark VI Speedtronic turbine control and Innovation Series rack architecture.
- Q: What do the front-panel LED indicators represent?
- A: The IPOK and MPOK LEDs provide visual feedback indicating internal power rail health and system microprocessor operation.
- Q: What should I check first if the rack cards fail to power up?
- A: Verify the 1 Amp input fuse on the board, check the physical seating of the P1 backplane connector, and observe whether the IPOK/MPOK LEDs are illuminated.
