The GE DS3800HUMB is a Universal Memory Card used in the GE Speedtronic Mark IV series of turbine and generator control systems. It’s a legacy component, no longer in production, and is designed to be a versatile storage solution for the control system.
Function and Purpose
A Universal Memory Card is a circuit board designed to be adaptable to various types of memory components, such as RAM (Random Access Memory) or ROM (Read-Only Memory), regardless of their specific format. This design approach was a forward-thinking way to accommodate different data storage needs within a standardized hardware platform.
The card’s key roles in the Mark IV system include:
- Data Storage: Providing memory capacity for various types of data, including control algorithms, real-time sensor readings, and system configurations.
- Compatibility: Its “universal” design allows it to be used with a wide range of turbine control system architectures, making it adaptable to different turbine models.
- Upgradability: The board’s design can support memory upgrades, allowing new control algorithms and features to be integrated without replacing the entire memory infrastructure.
- Reliability: Turbine control systems are critical components, and this card is engineered with robust components and error-checking mechanisms to ensure data integrity and system stability.
Technical and Design Features
The DS3800HUMB is a robust, industrial-grade circuit board designed to operate in a demanding environment.
- Legacy Part: The “DS3800” prefix indicates that it belongs to the legacy Mark IV series.
- Components: The board is populated with multiple erasable programmable read-only memory (EPROM) modules and 10 jumpers. EPROMs are a type of ROM that can be erased and reprogrammed, which allows for software updates.
- Reset Switch: It features a reset toggle switch that can be used by a qualified technician to address sporadic issues or situations where control signals become out of sequence.
- Physical Features: The card has a modular connector on one end and retention levers on the other for secure installation and removal. It also includes a red indicator LED for status updates.
