The GE DS200TCPDG2B is a Power Distribution Module (PDM), also known as a Power Distribution Board. It is a critical component in the GE Mark V Series Gas and Steam Turbine Control Systems.
Functionality and Features
The primary function of this card is to manage and distribute 125 VDC power to various other boards and cores within the Mark V system, including the TCPS boards in the I/O cores and the main Control Engine. It is not a CPU card, but rather a robust power management board.
Key features of the DS200TCPDG2B include:
- Switches and Fuses: The board is equipped with multiple toggle switches and fuses. The switches allow technicians to individually power down specific cores for maintenance or troubleshooting without affecting the entire system. The fuses provide protection against over-current conditions, safeguarding the connected components.
- LED Indicators: It has a series of “OK” LEDs that provide a visual status for each fuse, making it easier to identify a blown fuse.
- Redundancy: The board is designed for high reliability and can be used in redundant system configurations, such as simplex, dual, or Triple Modular Redundancy (TMR), to ensure continuous and fault-tolerant operation of the turbine control system.
- No Software Configuration: This is a hardware-based board and does not require any software configuration.
In summary, the DS200TCPDG2B acts as the central hub for power distribution within the Mark V system, ensuring stable and protected power delivery to the control and I/O components.
