The GE DS200SHVIG1B DS200SHVIG1BGD turbine control RAM board provides memory expansion for Mark V systems. This board stores real-time data, diagnostic logs, and application variables. You will find this RAM board in Speedtronic Mark V turbine cabinets. Its high-speed memory supports deterministic control loop execution.
Memory Architecture
This RAM board uses 32 MB of high-speed SDRAM for data storage. Consequently, it handles large diagnostic logs and trend data efficiently. The GE DS200SHVIG1B DS200SHVIG1BGD also includes 8 MB of flash memory. Moreover, a dedicated memory controller manages all access timing. You can expand system memory without changing the main processor board.

High-Speed Memory and Data Storage
The unit includes 32 MB of SDRAM for real-time data processing. Therefore, it stores extensive trend logs and diagnostic buffers. This board replaces the DS200SHVIG1BGD version without any configuration changes. Simply remove the old board and install this one. GE designed this RAM board for single-slot installation. Hence, it fits directly into existing Mark V rack positions.
Six PCB layers separate high-speed memory traces from power lines. Three connectors handle all backplane, diagnostic, and status signals. The GE DS200SHVIG1B DS200SHVIG1BGD holds 470 µF of capacitance for stable operation. Accordingly, it maintains memory contents during minor power fluctuations. Eight status LEDs show memory activity and board health clearly.
Installation and Compatibility Guide
The board automatically configures itself for the host processor. No jumpers or switches require manual setting. The GE DS200SHVIG1B DS200SHVIG1BGD works with all GE Mark V processor boards. Always verify processor compatibility before installation. Proper seating of the board ensures reliable memory access.
The flash memory stores application code and configuration data. This non-volatile memory retains data after power loss. The GE DS200SHVIG1B DS200SHVIG1BGD expands turbine control memory capacity significantly. Installation requires careful handling of static-sensitive components. This board operates in non-condensing environments with adequate cooling.
