GE DS3815PDLB Memory Card w/PROMS HMHA

الوصف

The GE DS3815PDLB is a Universal Memory Card with PROMs for the GE Speedtronic Mark IV turbine control system. Its primary function is to provide the main processor with expanded memory, specifically for storing control programs and critical system data.

Function and Purpose

The DS3815PDLB is a support card, not a processor itself. It’s a key component in the system’s human-machine interface (HMI) boards, often labeled as HMHA cards. The “PROMs” in the name refer to Programmable Read-Only Memories. This means the card contains memory chips that can be programmed once with the turbine’s specific control logic, which is critical for safety and operational consistency. The “universal” designation indicates that the card is versatile and can be configured for different memory-related functions, such as data storage, program backup, or as working memory for the processor. By providing this expanded memory, the card allows the Mark IV system to execute complex control algorithms, store event logs, and manage the extensive data required for a turbine’s operation.

Related Components

As a memory card, the DS3815PDLB works in conjunction with other components of the Mark IV system:

• Processor Cards: The main CPU of the system, like the DS3800HCDA, uses the DS3815PDLB to access and execute control programs and to store critical data.
• Backplane Cards: The card plugs into the system’s backplane (e.g., the DS3800XCIB), which provides it with power and a data bus to communicate with other modules.
