Product Introduction
GE DS200SIOBH1AAA is a SC2000 VME I/O board for the GE Speedtronic Mark V control system family. It is designed to provide configurable input/output interface functions for industrial and turbine control applications within the Mark V platform.
The board is identified as a SC2000 VME I/O board in GE and Mark V documentation, and it is intended to be installed in a VME rack assembly using a VME P1 connector, occupying one full VME slot.
Hardware features include 20 jumpers, 3 switch blocks with 6 switches each (18 switches total), 1 status LED, and a 40-pin connector. The jumpers on the original board are set to factory defaults, and alternate jumper settings may change board operation.
The status LED indicates the processing activity of the board and provides an initial troubleshooting reference when the drive or control system is powered. Because public documentation for the exact DS200SIOBH1AAA suffix is limited, the detailed I/O channel assignment, signal types, jumper map, switch block functions, and 40-pin connector pinout should be verified from the physical board label and GE Mark V manuals before installation.

Note: The SC2000 VME I/O function, VME P1 mounting, 20 jumpers, 3 switch blocks, 1 LED, and 40-pin connector are documented for the DS200SIOBH1 family. The exact I/O channel assignment, signal types, jumper map, switch block functions, and AAA-specific configuration should be verified from the physical board label and GE Mark V manuals.
Quality Control Process (DYNAMIC GENERATION)
- Visual and label inspection. We check the part number, suffix, PCB surface, connectors, jumpers, switch blocks, LED, and mounting hardware for damage or corrosion.
- SIOB function verification. We confirm the board matches the DS200SIOBH1 SC2000 VME I/O description and is not mislabeled as a different Mark V board type.
- Jumper and switch block check. All 20 jumpers and 3 switch blocks are recorded and compared against the original board or system documentation.
- Connector and continuity check. The 40-pin connector and VME P1 interface are verified for correct pin continuity and no short circuits.
- Final packaging. After passing inspection, the board is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Confirm SIOB function before installation. DS200SIOBH1AAA is a SC2000 VME I/O board; do not substitute it with TCQA, SDCC, SDCI, SHVM, or other Mark V I/O boards without verification.
❗ Copy jumper and switch settings from the original board. The 20 jumpers and 18 switches affect board operation; do not change them without verification.
❗ Label all connectors before removal. Miswiring the 40-pin connector or VME P1 interface can cause incorrect I/O behavior or system faults.
❗ Record LED status before removal. Document LED behavior for troubleshooting reference after replacement.
❗ Verify VME rack compatibility. Confirm the board is installed in the correct VME slot and rack configuration before replacement.
❗ Observe ESD safety. The board contains sensitive I/O and logic circuitry; always use anti-static wrist straps and handling procedures.
❗ Handle as ESD-sensitive equipment. Always use anti-static wrist straps and handling procedures during removal, installation, and storage.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| GE | GE | Direct | Same part number; verify jumper map, switch settings, and VME slot assignment. |
| GE | GE DS200SIOBH1 variants | Needs Adaptation | Same SIOB family; suffix differences may affect revision or configuration. |
| GE | GE DS200SIOBH1ABA | Needs Adaptation | Same SIOB family; verify jumper, switch, and I/O configuration before substitution. |
| GE | GE DS200TCQA / DS200SI0CG1AEA | Not Compatible | TCQA is an RST analog I/O board for turbine cores; not a direct replacement. |
| GE | Mark VIe / IS200/IS220 modules | Not Compatible | Different platform and architecture; not a direct replacement. |
Benchmark highlights
