GE DS200UPLAG1B LAN Power Supply Card

الوصف

The GE DS200UPLAG1B LAN Power Supply Card is a critical component used in the General Electric Mark V Speedtronic Turbine Control System.¹

Its function is essential for the communication and fault-tolerant architecture of the turbine controls.²

⚙️ Function and Series Context

• Core Function (³$\text{UPLA}$): ⁴$\text{UPLA}$ stands for LAN Power Supply Circuit.⁵ This board is responsible for generating and regulating the specific ⁶$\text{DC}$ voltages required to power the Local Area Network (⁷$\text{LAN}$) communication components (like ⁸$\text{ARCNET}$ or ⁹$\text{DLAN}$ chips and transceivers) on the main controller boards.¹⁰
• Application: It is used in control systems for large industrial equipment, primarily gas and steam turbines, and sometimes in ¹¹$\text{GE}$ Drive Systems (e.g., ¹²$\text{EX2000}$ Excitation Control Systems).¹³
• Criticality: By ensuring a clean and stable power supply to the ¹⁴$\text{LAN}$ communication bus, the ¹⁵$\text{DS200UPLAG1B}$ maintains the integrity of the data exchange between the redundant ¹⁶$\text{R}$, ¹⁷$\text{S}$, and ¹⁸$\text{T}$ control processors, which is vital for the system’s fault-tolerant operation (¹⁹$\text{TMR}$).²⁰

🔍 Part Number and Revision Breakdown

The abbreviated part number ²¹$\text{DS200UPLAG1B}$ is a base part number that specifies the function and a major revision:²²

When you see a card in a panel, it will typically have minor revisions appended to this base number, such as $\text{DS200UPLAG1BAA}$ or $\text{DS200UPLAG1BDA}$.

Replacement Note

The ²³$\text{UPLA}$ card is often populated with ²⁴$\text{DIP}$ switches or jumpers that must be precisely configured to match the old board’s settings.²⁵ These settings define the board’s operational mode for the specific turbine application. Always refer to the system documentation or copy the settings from the card being replaced.
