• Illumination Condition: LED glows when VME rack accesses the DS200SIOBH1ABA board.
• Status Meaning: Indicates normal functional status. Confirms board communication with Mark V system.
• Troubleshooting Aid: Quick visual confirmation. No software needed for basic operational check.

VME Rack Integration

• Mounting Location: Installs in VME rack assembly. Connects to VME P1 connector.
• Slot Occupation: Occupies one full VME slot. Standard Mark V form factor.
• Rack Compatibility: Functions alongside other VME modules in Speedtronic control system.
• Physical Retention: Secures with mounting screws. Two-hand removal required.

Product Lineage & Revision Status

• Parent Board: Derived from DS200SIOBH1. The ABA variant includes three functional revisions.
• Revision Impact: Altered performance specifications. Dimensions may differ from original H1 documentation.
• Documentation Note: Original manuals describe parent board. ABA revision supersedes those specifications.
• Legacy Status: Mark V series discontinued. This board remains a critical spare for active turbine installations.
• Speedtronic Heritage: Uses patented GE technology dating from Mark I (1960s) through Mark V.

Installation Procedure

• Old Board Removal: Remove mounting screws. Use two hands. Avoid contact with other drive components.
• ESD Protection: Flatten static protective bag on clean dry surface. Place old board on bag.
• New Board Handling: Slide replacement from sealed bag. Carry with two hands. Place adjacent to old board.
• Jumper Matching: Compare jumper positions. Set new board jumpers to match old board exactly.
• Switch Matching: Configure all three switch blocks. Match each of the 18 switch positions.
• Verification: Board will behave identically. Drive performance remains consistent after replacement.

Frequently Asked Questions (FAQ)

1. What is the difference between DS200SIOBH1 and DS200SIOBH1ABA?

The ABA variant carries three total revisions. The parent H1 board is the original SC2000 VME I/O Board. The ABA version includes updated performance specifications. Always verify jumper mappings, as ABA revisions may differ from H1 documentation.

2. How do I determine the correct jumper settings if I lost the old board?

You need the original GE manual for your specific turbine application. Factory defaults are preset on the board. However, drive performance may require specific non-default positions. Contact technical support with your Mark V model number for guidance.

3. Which jumpers cannot be changed?

GE does not publish a universal list. Some jumpers have only one supported position. Attempting to move these jumpers damages the board or causes unreliable operation. Always assume any jumper not mentioned in your manual is fixed.

4. Does the LED indicate board failure if it turns off?

No. The LED only glows during VME access. It is not a continuous power indicator. The LED may turn on and off during normal operation. Absence of light does not automatically mean board failure.

5. Can I install this board in a Mark VI VME rack?

No. GE designed the DS200SIOBH1ABA specifically for Mark V systems. Mark VI uses different backplane architecture and I/O packs. Physical fit may differ. Electrical compatibility is not guaranteed.

6. How do I confirm conformal coating presence on this board?

Inspect under bright light. The coating appears as a thin transparent gloss. It covers traces and component bodies. The Group 1 designation in the product number confirms factory-applied coating. No field application required.

7. Buying advice: Should I choose the ABA revision over available H1 stock?

Yes. The DS200SIOBH1ABA includes three revisions absent from the original H1. GE released these revisions to resolve field issues. The ABA variant is the most mature SIOB board for Mark V systems. For legacy turbine support, ABA is the preferred spare.

8. Why does the installation procedure emphasize two-handed handling?

VME boards are long and component-heavy. One-handed carry risks flexing the PCB. Flexing cracks solder joints and damages surface mount components. Two hands distribute support evenly. This rule prevents hidden mechanical damage.
